01 — ABOUT

Writing code that
actually works

I'm a product engineer who likes difficult systems: mature enterprise frontends, mobile release automation, local-first apps, and research software with explicit safety boundaries.

My day job is still grounded in Angular and TypeScript, but the things I ship now span Rails, Python, Swift, Bun, FastAPI, and CLIs. The common thread is dependable product engineering: clear authority, useful interfaces, strong tests, and code that can survive real use. Based in Tirana, working with teams across Europe and the US.

Flagship / Mobile delivery01 / 11

For mobile teams tired of signing and release friction

MySigner

A Rails dashboard, API, and Ruby CLI that turn mobile signing and store delivery into one repeatable workflow—from certificates and profiles to TestFlight or Google Play.

The product moment

Run mysigner ship testflight; the tool validates the build, matches signing assets, and drives the upload.

For developers using AI coding agents

Aichu

A local proxy that detects secret-shaped values in outbound prompts, swaps them for typed placeholders, then restores preserved values in streamed responses.

The product moment

Paste a log containing a credential. The provider receives a placeholder; the original value stays on your machine.
