I take small products all the way to shipped.

Built and running

• VowQuiz

  vowquiz.com

  Wedding quizzes for the reception. Couples write a “who’s more likely to” round; guests join with a six-character code — no account, no app — and the leaderboard fills up between courses.

  A whole product rather than a demo: accounts and Google sign-in, themes, a free tier and a paid one billed through Paddle, an end-to-end test suite, and an image that ships on every push.

• câtproduc

  catproduc.ro

  Solar production, shared with friends. Your inverter pushes a reading every minute; you get a page with live output, a daily curve and years of history.

  Most of the work is about telling the truth. Measured, estimated and self-declared numbers are drawn differently so no roof looks better than it is, and a panel producing nothing at dusk is never confused with an inverter that has quietly stopped talking.

  • Next.js
  • React
  • Drizzle
  • Postgres
  • Home Assistant

• KeySound

  keysound.filippopa.com

  Mechanical keyboard sounds for your Mac. A menu bar app that plays Cherry MX switch audio as you type.

  Separate key-down and key-up samples with randomised pitch, about three milliseconds from press to sound. No dock icon, no window, nothing to configure beyond a volume slider.

  • Swift
  • AppKit
  • AVFoundation
  • CoreGraphics

How they get built

One person, from the empty repo to the running container. I design the data model first, keep the stack boring — Postgres, a typed ORM, one deployable image — and put agents to work on everything that is more typing than thinking. Every one of these builds and deploys itself on push, and runs on hardware I look after.

Ten years of shipping behind all this — the longer version.
