Lars van Teeffelen

Curious by nature, backend by choice.

I'm Lars, a backend developer from Noord-Brabant, in the south of the Netherlands. It all started in 2018 with Minecraft: I wanted the game to do things it couldn't, so I taught myself Java and began writing my own plugins. What started as a hobby quickly became the thing I couldn't stop doing.

That curiosity turned into a career choice. I studied ICT Software Development on the accelerated track, which let me skip the final year entirely. Along the way I picked up PHP, got my first taste of real-world development as an intern, and was asked back afterwards to keep building on what I'd made.

Today I'm a backend developer at an internet agency, where I started as an intern and worked my way into the team. I build platforms with Pimcore and Symfony that bring together product information, master data, digital assets and content. I like code that's clean and readable, databases that are designed rather than accumulated, and systems that are easy for the next person to pick up. See my full experience.

How I work

  1. Clarity over cleverness

    Code is read far more often than it is written. I aim for solutions the next developer understands at a glance, and that includes future me.

  2. Data deserves design

    Most problems start in the data model. A well-designed schema makes features easier, queries faster and bugs rarer.

  3. Always learning

    The web never stands still, so neither do I. I keep up with the PHP and Symfony ecosystems and enjoy picking up new tools along the way.

Hobbies

More than a programmer.

When I'm not writing code, you'll usually find me doing one of these two things. Both, it turns out, have a lot in common with building software.

Video games

Gaming is how I switch off after a day of code. Good games are masterclasses in systems design: every mechanic, rule and reward is logic someone carefully tuned. It's hard not to notice that as a developer.

Music production

I make music in FL Studio. Producing a track feels surprisingly similar to building software: you layer small, well-defined parts, like a kick, a bassline or a melody, until they work together as a whole.

Got something in mind?

Let's build something solid.
