Hi there, I'm

Tom
Grootjans

Runner, lifter and padel enthusiast from Zoetermeer. By day I build software at Valicare, the rest of the time you'll probably find me outside, chasing a new personal best.

About me

Nice to meet you.

I'm Tom, a Zoetermeer local who likes things that are simple, honest and built to last. That goes for the software I write and for my training schedule.

I've spent most of my working life building the engine room of websites and platforms. I enjoy small teams, helping colleagues grow and keeping things calm when deadlines aren't.

Outside of work you'll find me on the padel court, in the gym or out on a run, usually with a new goal on the horizon.

Projects

Things I've made, and things I'm making.

A mix of work I'm proud of and personal projects, on and off the track.
  • PersonalNuxtTailwind CSSTypeScript

    This website

    A calm little home on the internet. Designed from scratch and built with Nuxt on top of my own design system.

  • PersonalNuxtTypeScriptShip24

    Package tracker

    One overview for all my parcels: tracking codes, orders that arrive in several shipments, status, expected delivery and pickup point.

  • SportRunning

    Next big goal

    Placeholder: a race or challenge I am training towards. Swap this for the real thing.
