before 40.

I'm Edwin Boezelman — senior developer, autodidact, dad of two with one on the way. Spinsle is my one-person studio: small software products I'd actually use myself, built with agentic engineering as the force multiplier.

Projects

Tailend

In progress

A reliable memory for the internet — everything you save, collected automatically and searchable in one calm place.

WerkbonBot

In progress

A WhatsApp assistant for Dutch tradespeople. One message in, one finished werkbon out.

Footballclub.one

In progress

A live global leaderboard where football fans push their club up the table. Back yours for €5 — half of every backing is set aside for donation to War Child.

Hearback

In progress

Records your meetings, transcribes them, and lets you hear any moment back — so you can check what was actually said instead of trusting your memory.

Mondri

Idea

Notes, voice memos and calendar pulled into a weekly review of what actually mattered.

About

Software has been my craft for almost two decades. In that time the list of things I wanted to build grew a lot faster than the list of things I actually shipped. Spinsle is the project to fix that.

One filter decides everything: would I use this myself, or do I see real potential in it? If yes, it goes on the build list. If no, it stays an idea.

  • Pick problems I'd use myself. If I'm not the user, I'm the wrong founder.
  • Use agents for the plumbing, the boilerplate, the first draft.
  • Ship in small windows — mornings, evenings, between bedtime stories.
