Remembering Loafy

Loafy
Loafy, June 2021

It’s probably sad to say that a cat is your best friend. But, for better or worse, Loafy was my best friend. He’d been through a few different family members before I agreed to take him when I bought my first home late in 2009. I didn’t realize the blessing I was about to receive.

I’ve had a few cats that have had a lot of personality and Loafy was definitely one of them. When he was younger he used to tear up and down the length of my house chirping, for lack of a better word. He would come running from anywhere when he heard me open a can of food or a bag of treats. And like Mugsy he just seemed to know my mood, especially when I was down and would always try to cheer me up.

Because he’d gone through several homes I wasn’t always exactly sure when his birthday was. I was pretty sure it was in 2004 but was told June and March at different times. Regardless, last year he celebrated his 19th birthday. During the pandemic I had almost lost him. He started losing a ton of weight and being extremely tired. I found out he had hyperthyroidism and knowing that he hated pills or anything of the sort, and being blessed with resources, I decided to get him radiation treatment.

I was terrified. The only other time he’d been in surgery of any sort he’d had a really bad reaction to the anesthesia. Plus being so frail I was convinced I was about to lose him. Thankfully he pulled through, although I do think I annoyed the vets with how often I called to check on him. Unfortunately through the sickness and everything else he’d lost his hearing but other than that he was in pretty good shape for a teenage cat. Plus he now had a new quirk where he didn’t realize how loud he was and would scream. It used to drive me nuts. I’d give anything for it now.

Just before Christmas he started to be very tired and lose weight again. I knew something was up. I took him to the vet multiple times and they’d treated him for cold like symptoms. His kidneys had started to go a few years ago but had stabilized at stage 2 as I adjusted his diet. But just after I got back from visiting my family for Christmas he’d started to get real bad. They had done bloodwork only a few months before but I got him retested and that’s when they told me it’d progressed to stage 4 and he probably had a few weeks left at best.

I was devastated. I had prayed and begged God or the Universe or anyone that would listen for him to go peacefully in his sleep when his time came. But now I knew I’d have to once again make that difficult call all pet caretakers dread. His last weekend was the most difficult. I knew I wanted to use my vet but they were only open half days on Saturday and closed on Sunday. On Friday he was doing really bad but he rallied on Saturday and stayed stable until Monday morning.

But Monday I could tell it was time. He could barely hold himself up. He had lost all interest in food or treats. It was just time, as much as I didn’t want it to be. Life is cruel in making us choose to have our family put down, even if it may be a kindness in saving them from suffering.

It was January 22, 2024 and I had lost my best friend. Now it’s been just over 7 months and while I’m still so thankful that I got him in my Life and for so long, I do miss him so much.

The one consolation is back when Loafy was around 9 I decided he needed a buddy. So I had gotten a kitten named Grizzly. He’s about to celebrate his 11th birthday on Halloween and we both miss our best friend. Neither of us is as close to each other as we were to Loafy, but at least we still have each other.

The problems I’m excited to solve

I’ve recently been told that as someone who has passed 40, I should not talk about my age because that may hurt future chances of employment. I disagree with this for two reasons. 

One, ageism is one of the many “isms” people face in employment. It’s also one that seems to get less sympathy which is fair – with age usually comes resources, power, etc that cause this to be far, far less of a challenge than sexism or racism. And I am not trying to dispute or change that assumption. But I am someone with a lot of privilege, so I think I have an obligation to use that to talk about it since I can assume more risk.

Two, I think aging is a benefit. I am far more kind, empathetic, thoughtful than I was in my 20s and even 30s. I’ve suffered loss and experienced deep grief. I’ve not had my own children but I’ve helped in the raising of my niece and nephew as well as trying to be a good role model and source of advice for my younger cousins, of which I have many. I’ve gained a lot of perspective and patience that I didn’t have early in my career. I think that’s led me to be a better person and colleague, hopefully.

All that to say as I’m about to turn 45 in a few months and I reflect back on a programming career that, depending on whether you count personally or professionally is somewhere between 18-25 years, I’ve been thinking about what problems still excite me to solve. What kinds of opportunities or challenges still are processing in the deep recesses of my mind even as I’ve gotten better about shutting off once I step away from my keyboard. Because, like most programmers, even if I’m not actively thinking about some technical problems my mind is often running them on a thread somewhere.

At my current job at MassMutual I’ve worked on several teams, often concurrently. I worked on the relaunch team for the anniversary when I started, helping to build a new brand and site. On a “robo advisor” team, offering financial advice to our customers. On the authentication team handling login and signup. On the calculators team offering a suite of tools to determine how much of different types of protection our customers might need. Finally on a team that builds a tool that allows advisors to service their book of business and customers, handling common transactions, and providing policy details. Also a few other teams here or there to help and, again, I was often working on two or more of these teams concurrently.

With the exception of all but the first these are what I’d refer to as application teams – ones building a specific application for a purpose. But for the last several years, since before even the pandemic I believe I’ve honestly lost track, I’ve also worked on our design library team. Building what one of my colleagues described as “Blueprint Design System is MassMutual’s design system that includes reusable styles and components that are consistent, accessible, and responsive”.

Aside, this got further confusing as there already was a blueprint CSS framework which only I was aware of and hadn’t been updated in around a decade when I brought it up, again showing my age. Also MassMutual later acquired a company with Blueprint in the name adding internal confusion at times.

My point is that this last team has been one of the great joys of my career for multiple reasons. 

First, on most previous teams I’d worked with I’d been the sole “UX Developer” type. Which is to say I was the one that did most, if not all, of the HTML and CSS / SASS development usually with only cursory review by the rest of my team. This was the first time I could actually both give and receive constructive criticism from other developers that had an interest and skill set very similar to mine. As a result my skills in both writing and evaluating code grew immensely. And I learned a great deal about what I should comment on and the tone it should carry, through a lot of mistakes.

Second, the team was a mix of developers and designers working together to provide patterns in Figma, HTML / CSS, and React depending on the user’s need. Which is to say if someone was a designer they could use Figma components to build designs for the applications they worked with. If someone was a developer and used React they could use our React components and if they used some other JavaScript library they could use our CSS file and HTML patterns to build their own components. But to my first note here being able to collaborate with people in design was very rewarding as it caused me to rethink problems and challenged many assumptions I had, causing me to grow to be less rigid as it was less of design “throwing something over the wall” and more of a collective effort. We both grew more invested in each other’s success by this partnership. Plus I was fortunate to work on a team just loaded with lovely and talented people, which is always a bonus.

Third, approaching problems from a library versus an application perspective causes you to think differently about solutions. It goes back to that description from my colleague – reusable and consistent. How do you make something that is useful to teams – managing that slider between specific and generic? How do you offer some variants while also constraining them so it’s not just a soup of helper classes and multiple components that all solve similar problems only slightly differently so that it’s confusing what teams should use and the product cohesion suffers? Because, again, the goal is to provide a library in which multiple teams are using so that the site looks more like it’s built by one team instead of dozens each building small sections of it.

We built this on top of the bootstrap library, something which several jobs and multiple freelance gigs I’ve worked with have used so I had a ton of familiarity with. I’d also grown to understand its problems – by trying to be everything to everyone it suffers. Internally we took several measures to limit this like not including almost all of the utilities and helpers but also being mindful of the examples we used – trying to limit the variants we talked about in our internal documentation even if someone familiar with the underlying framework could understand more options might be available, although potentially not branded.

This also gave us some unique challenges with branding and cohesion. Often we would want something to look a certain way, say like an H2, but we would not know where in the code it may appear semantically. In the bootstrap model you’d use some helper classes. But where we had so many consumers we wanted to make it simple if something changed – like if a card header suddenly went from looking like an H2 to an H3 – so they’d have minimal code changes beyond ticking up the version, if we could help it. One of my colleagues started playing with SASS placeholders and it’s something we ended up using extensively.

This would allow us to build a bunch of typographic styles and instead of having them assign a class we’d use a placeholder so we could do something like .card .title { @extend %h2; }, moving the helper classes from the HTML to the SASS basically. Which means if later on it should be %h3 or %h4 we’d simply change the SASS, tick up the version, and they’d update – no further code changes.

Maybe this is a simple thing and everyone is doing it. I know in the bootstrap SASS they do something similar, though often through mixins instead. But it just was something I found exciting and powerful, enabling me to solve problems in a much cleaner way. And that was many of the things I found on this team – when I had to think about how to build a library to help other people, what concessions and trade offs did I have to make in order to make their lives as easy as possible? That was interesting and kindled my passion for my craft and work.

I think the library has brought a lot of value. Many of the teams at MassMutual use it, meaning they don’t have to write their own CSS, patterns, or components – saving them untold amounts of time. The company benefits as it’s more consistent in design and branding, as well as being responsive and accessible since that’s built into the library components. And those of us working on it enjoy working with each other to solve problems as well as the reward of hearing feedback from other developers who benefitted.

So to answer my original question – these are the types of problems I’m excited to solve. Using my skills and experience to provide library components that save my colleagues time and effort while also providing the company I work for with multiple types of value. Finding unique and interesting ways to solve those problems and manage the tradeoffs that are inherent in anything we do. Using my skills and talents to help people in whatever way I can, even if it might not change the world.

I hope I can continue to be blessed with opportunities to solve problems like this for however long the rest of my career is.

Hiring a Senior Developer

A few years ago I took part in a working group for a large company I was working for. In a highly competitive market, especially at the time, identifying senior developers – specifically talented ones – was a big problem. Even more so for a company that while profitable and stable wasn’t exactly the first one developers thought of.

There are many common ways to evaluate a developer. Often coding exercises are employed but those are more often for people just starting out so you can evaluate that they have the basic skills for the position. Puzzles, like the ones Google has used, can help to discern how someone thinks about and approaches a problem – “how many X can you fit in Y” for example. 

My argument at the time was that if you’re trying to find a senior developer, maybe this wasn’t the right path. While it is possible to have say 8+ years of experience and still not be a very good developer, I didn’t think a coding exercise was going to help us here. Especially if you’re looking for a strong, skilled developer. There was a real risk that if we asked too much of them or bored them, they’d walk away because they had so many options. So how do you balance that trade off – not pushing away desirable candidates but finding out enough to feel confident in your hiring decision?

So we started with the question: what are we really looking for when we say a senior developer? For example imagine you have 3 levels – beginning, intermediate, and advanced then how do you define when someone crosses over from one to the next? While years of experience is important, it’s not the best metric. I’ve met developers with 2 years of experience that I trust much more than some with 20 years of experience. So we started to tease out what we really meant and came up with several metrics.

  1. Experience. While it’s not the most important, it is important. Mainly in that over time you see different ways to solve problems, more importantly the wrong ways to solve them. You learn from mistakes, not successes. Often one thing that makes me trust a developer more is when they are presented with a problem their first instinct is not “how do I solve this?” but “should I solve this / what is the real problem we’re trying to solve?”. 
  2. Identifying complexity. This is important in grooming to make sure you have tickets that are of reasonable size. But also in understanding that everything is a trade off – so are we making the best one available? It’s also spotting those things that seem simple at first glance, until you start to pick them apart. Something that builds trust with me is when someone asks probing questions that cause others to think beyond the surface and go something like “oh, that’s interesting, yeah what about X? Or what do you expect when Y happens?”
  3. Communication. Think Reddit’s “explain it like I’m 5”. Can they break down complex, technical problems and solutions into something digestible to non-technical folks? Can they ask the right questions to make sure we both understand and actually address the problem? Can they tease out expectations? Can they mentor and level up other developers through pairing and code review – guiding them to solutions and not solving it for them?
  4. Technical review. Can they help non-technical people list out technical requirements for tickets? Can they understand dependencies on other libraries or teams? Can they spike on a new library, plugin, etc to understand the solutions and drawbacks it offers?
  5. Humility. Can they take accountability when they make a mistake or bug? Can they show grace to others when they do the same? Can they keep their ego in check – like using a library that does most of what we want instead of just immediately writing a new one themselves? Can they solve only the problem at hand, not future problems we may never get to and which will only add complexity to the code base?

With all that in mind one of my favorite suggestions was that instead of presenting a candidate with a coding exercise we give them code to review instead. This would allow us to see what they focus on and ignore. Whether they identify problems we expect, or ones we didn’t think about. Give us an idea of the tone and how constructive the feedback they might provide is. It’s more like an essay question instead of a multiple choice. As I said before, can they guide instead of tell? 

An article I read that stuck with me talked about something along the lines of “it’s not about making every review be an A+, it’s about improvement. Making a B into a B+, making a C into a B. Etc.” That really struck me as someone who can be a bit of a perfectionist and have unreasonable expectations of myself – it’s important to not push that on others, only to help, to teach, to foster learning, and most of all to be kind.

We’ll always find ways to improve on the code past us wrote as one of my favorite webcomics lays out expertly. “Perfect is the enemy of good” after all.

Finally, on hiring in general I saw something interesting on Hubspot that they do some version of near the bottom of most of the developer positions I saw there. “We know the confidence gap and imposter syndrome can get in the way of meeting spectacular candidates, so please don’t hesitate to apply — we’d love to hear from you.” with links to articles about what they mean by “confidence gap” and “impostor syndrome”. But I thought that was a really interesting way not to drive away quality candidates and be inclusive.
