Marcel Tuinstra / Dronten / software / side quests

Code, brain dumps and side quests. Sometimes with sand in my shoes.

I build software, tinker with side projects and write down things I do not want to rediscover next month. Work-work lives at tuinstra.dev. This is the labelled junk drawer.

Things I build, fix, park and keep around because my brain took another turn.

Brain Dump

Loose thoughts about software, product work, tools, sport and small lessons. I do not use Instagram, so this is the outlet.

Client work, assignments and the tidy shirt live at tuinstra.dev.
