The abbreviation MVP usually stands for Minimal Viable Product, at least if
you’re working in the field of software engineering. But today I want to
talk about a different kind of MVP: The Most Valuable Programmer.

Just like the Minimal Viable Product, the Most Valuable Programmer isn’t a
concrete concept. Rather, it’s a goal that you strive towards. Also, it’s
not about being the most valuable among your peers. Instead, it’s about
becoming the best version of yourself. Let me elaborate…

A Younger Me

The other day I was reminded of a conversation I had with a senior developer
probably close to 15 years ago. I don’t remember exactly what had gotten
into my head, but I had taken it upon myself to micro-optimize a few large
PHP files. And this was in the days before we used op-caching, so files were
parsed over and over for every request. In order to optimize this I changed
all the double-quoted strings to be single-quoted instead, because I had
read somewhere that parsing those was 11% faster (or something to that
effect) due to the lack of escape sequences.

All of this had resulted in a diff that was rather huge and chock-full of
tedious changes. And it was this senior developer who had been given the
pleasure of reviewing those. He gave me a bit of a scolding for creating
such a large diff without prior discussion, which had caused him quite the
headache, but he was surprisingly polite about it. It might have been my
saving grace that he assumed that I had used an automated formatter on the
code, because as he mentioned, nobody in their right mind would spend the
time to do such a thing by hand. I agreed.

But this was also before the days that automated formatters were really
commonplace and I had in fact done everything by hand. Oh silly me. I knew
very well that it was not in my best interest to admit it at the time, but
I had absolutely been stupid enough to have wasted several hours replacing
string quotes and making other tedious changes, and in turn had wasted my
senior’s time reviewing all of that.

There might even be some interesting pedagogical aspect to how this lesson
was taught. Had he really assumed I was using an auto-formatter, or was he
just giving me the benefit of the doubt? Had the lesson stuck precisely
because his polite snark had brought shame upon myself? Regardless,
the lesson was learned and it helped me take one of those many steps towards
becoming a better programmer. A more valuable programmer, if you will.

Code versus Value

I have been coding for about 28 years now and I used to take great pride in
my code. I would love to draw diagrams of architecture, I had a rigid coding
style, followed meticulous interface guidelines, and always had performance
on the top of my mind. It’s really no wonder I was proud of my code, because
it truly was a thing of beauty. Or so I thought.

I suppose it might have been a luxury that was afforded to me because I
started programming even before high school. It allowed me to perfect my art
without any pressure from employment, and frankly without any consideration
for what really matters. I learned immensely from those early years of
programming, but I think my appreciation of the code itself might have been
something that held me back for many years after.

If you ever want to become a better programmer, please take this advice:
Don’t even try to become the best programmer. Nobody will
agree what it means to be the best programmer anyway, so it’s a futile goal.
Chasing of wind. Instead, try to become the most valuable programmer.
Value is still a rather abstract concept, but at least it can be tied to
more concrete goals, such as business value.

I think one of my biggest mistakes was an abstract idea that I believed in
for many years: The idea that code is valuable. It’s not. Code is a
Once code is written it needs to be reviewed, it needs to
be maintained, it may need to be debugged, or rewritten, or even thrown
away. But once it’s there, it becomes a time sink. There is no value in
code. There is only value in value. That may be a tautology, but it’s so
fundamental that it bears repeating: You gain value from solving the
problems that your code solves, not from the code itself. The less code you
need to solve your problem, the better.

Consider this: If you’re an engineer you get hired to solve problems. Code
may be your weapon of choice, but you don’t get paid to deliver code. You
get paid to solve problems. The more problems you solve, the more value you
deliver. The more code you deliver, the more of a burden you become…

So how do you avoid becoming a burden, and how do you become a valuable
programmer that solves many problems? Prioritize. And a good trick to
teach yourself to prioritize is a change of mindset: You’re not trying to
become a valuable programmer. You are a valuable programmer.
You are your own most valuable asset. And what are your scarcest resources?
Time and energy. There’s only so many hours in a day, and there’s only so
much energy you can muster. Don’t waste it on code formatting, but help out
solving the problems the business or your project needs solving most.

Code Style

I suppose I could have stopped there, but I had all these topics in mind and
I’m not going to waste them. And since they’re all topics that most
programmers should answer for themselves at some point, we might as well get
on with it. We already touched on the subject of code style, so it’s a
natural place to start. It’s also a good one to highlight a fundamental
contradiction in all of this: Many things are simultaneously important, and
they all deserve our attention. Prioritization isn’t merely picking up
what’s most important and dropping everything else. It’s about finding a
balance that ensures your basic needs are met so that you can spend most of
your time focusing on the things that matter most.

Code style is important for many reasons. We want our code to be readable so
our peers can review it and so that we ourselves can still understand it if
we have to dive back in later. If everyone in a team follows their own style
it tends to distract from what the code is trying to achieve. Code written
in a different style from what you’re used to is harder to read because it
goes against your expectations. Compare it two people speaking in different
dialects: They might both be speaking English, but it becomes harder to
focus on the message.

But ultimately, it doesn’t matter so much which dialect you speak, so long as
everyone speaks the same. For software, that means agreeing on a code style
and staying consistent. There are countless debates to be found on all the
minutiae so I’m not going to repeat them here. Make a choice that makes you
happy as a team and stick with it.

And make sure you use automation to verify your style. No better way to avoid
wasting other people’s time on nitpicking than to let the machines do it.


Oh, the joys of correctness. Both of utmost importance, for obvious reasons,
and a potentially endless timesink, for much more subtle ones. Making sure
your code is correct is one of the primary responsibilities of a programmer.
Bugs may bite your users, and that’s not good for business. Not to mention
that haunting them down is also a nasty time-consuming job that nobody likes
to do. Better to avoid them in the first place.

So our code should always be correct, right? Well, it depends.

For example, let’s assume you’re writing a script to handle some automation
within a repository. Maybe the script wouldn’t be able to handle file names
that are not valid UTF8. That’s a bummer, and you can argue that’s not very
correct. But if none of the files in your repository would cause it any
trouble, it’s certainly correct enough.

That’s a very different story from when you’re building a client application
that you distribute to end users and which needs to be able to handle
arbitrary paths on their machines. People may use all kinds of locales, and
sooner or later you might run into someone with file names that aren’t valid
UTF8. The threshold for correctness may differ very much per situation.

In general, I think it makes sense to say that the programs we write should
produce correct results for all the inputs that may be reasonably expected.
Maybe you work in an industry where bugs can create life-threatening
situations, in which case you probably have a very strict interpretation
of what may be “reasonably expected”. But going beyond the requirements for
your problem domain is often a recipe for writing lots of code with little
value. Small chance anyone will thank you for it.


DRY stands for Don’t Repeat Yourself. Rather than copy-pasting code and
modifying tiny bits to fit different use cases, it’s usually better to write
code that’s a bit more reusable and can be used for both use cases. But this
by itself presents another trap that junior programmers may fall into.

Mantras, when taken to any extreme, usually lead to them being applied to
situations where they backfire. DRY was invented to ease maintainability.
After all, if you later need to update the code, you likely only need to
update it in one place instead of hunting down all the places it was copied
to and possibly missing some. That’s great and all, but if you keep on
extending a single function with various options and branches to make it
cover an increasing amount of use cases, that function itself will become a
hazard to maintainability.

In this specific case, it would probably be better to split a large function
into smaller ones. Then you can compose them back into larger,
use-case-specific ones, even if that introduces a bit of boilerplate. But in
the more general sense, always try to question what the purpose is for a
given guideline. Following guidelines isn’t bad, but learn to recognize when
it’s a good time to step away from them.


Many a programmer’s darling. If nobody appreciates the beauty of your code,
at least you can revel in how many allocations you saved. I know — I
once replaced hundreds of quotes because supposedly that made parsing them
11% faster on code that was never a bottleneck in the first place.

Just realize, that unless you work on the Linux kernel or some special
embedded domain, obsessing about performance is wasting your own energy and
not delivering any real kind of value.

That’s not to say that performance isn’t important (all of these topics are),
but delivering good performance is again very much about picking your
battles. Optimize your critical path, if you have any. Batch requests
instead of bombarding your API or database with dozens or hundreds of
requests. But you don’t add any value trying to optimize things that are
fast enough anyway.

Adding Value

We’ve covered plenty of examples to show that restraint is good. Don’t go
overboard and you’re halfway there on your path to becoming a valuable
programmer. But where should you focus your energy? How do you
add value?

Here is a random list of ideas that’s by no means authorative…

  • Try to understand the business’ motivation for functional requirements.
    Once you understand the problem domain well, you may be able to offer
    simpler alternatives that take less effort to implement.
  • Identify unaddressed problem areas. These can be technical such as
    common causes for bugs, but may as well be process-related or
    organizational, such as causes for reduced velocity or team morale.
    Do your research, then propose solutions. Offer yourself as willing to
    address them. Many times you’ll find you’re not the first to notice
    them, but it may just take someone willing to put in the effort.
  • Take your time reviewing your co-worker’s code. When looking at a pull
    request try to understand what problem they are trying to solve, and
    whether their solution makes sense in that context. Can you think of
    anything they might have missed? This is also a great opportunity for
    knowledge sharing. Don’t just point out what they missed, but if it’s
    a system you’re familiar with, you may also be able to offer some
    background as to why things are the way they are. You might even think
    of ways to improve the maintainability so the next person won’t miss the
    same thing.
  • Communicate. Make sure others know what you’re working on, and have some
    sense of what others are doing. If others are unaware of your work, they
    also cannot offer advise. You might think you have a good idea and want
    to surprise your peers with a working solution. But in an organization,
    surprises are rarely good, and you don’t want your good idea to
    interfere with someone else’s.

Don’t Forget Yourself

Thanks for making it this far. Hopefully I can offer you one last gem, as for
some this might be the most important advice of this piece: Don’t forget

I mentioned before that time and energy are your scarcest resources. I also
mentioned that prioritization is about finding a balance that ensures your
basic needs are met. If you run out of time, you might miss a deadline and
that’s not good for business. If you run out of energy, you may risk a
burnout and that’s not good for anyone, least of all you.

But before you run out of either, you usually enter a negative spiral that
can be recognized. If you have little time, it causes stress that can cause
you to burn energy faster. If you’re low on energy, you start to lack
motivation and you start taking more time to complete basic tasks. If you
notice these signs, it’s a very clear indication your basic needs are not
met and you need to speak up. If your manager has to ask why a
deadline was missed it’s too late. And if you have to take sick leave to
recover from burnout it is definitely too late.

There are many ways to prevent this negative spiral or to step out of it once
you notice the early signs. First of all, don’t over-promise as it’s a
surefire way of taking on more work than you can handle. But also if you
notice a particular task is draining your motivation, ask your peers for
help, or put it on the backburner instead of forcing yourself to finish it
at once. And if you feel a deadline is unreasonable, tell your manager well
in advance. Don’t beat yourself up if you cannot make it.

Make sure you take time for yourself, your family and/or your hobbies. For me
personally, reading up on and experimenting with technology used to be very
much of a pastime, though nowadays I often find myself writing
fiction[1] instead. I
love spending time with my wife and my son, and I can be perfectly content
not thinking about work or programming at all.

None of that compromises the idea of being a valuable programmer. You need to
relax and stay healthy to be happy. Only then can you keep up the energy to
keep improving yourself. Happy programmers tend to be more

And after all, you are your own most valuable programmer, so take care of

Love, Arend.
