Things Iactually shipped.
Three products that live outside a repository — a platform with real users, an app on Google Play, and the reference implementation behind my dissertation. Below them, earlier commercial builds.
heyengineers.com
I built and launched heyengineers.com on my own — architecture, backend, frontend, ML-driven content discovery, CI/CD and production operations. In its first four months it reached 500+ registered users and around 5,000 monthly visits across 40+ technical articles.
Mowqit
A privacy-first Android timer app, live on Google Play. Exact-alarm scheduling that survives Doze, release signing with R8 obfuscation and tamper detection, and a zero-data-collection architecture — the app ships without the INTERNET permission at all, so the privacy claim is enforced by the manifest rather than a policy document.
FaceApp
The working artefact behind my dissertation: roughly 3,000 lines of Ruby and Python demonstrating that an eight-layer attendance system — face verification, active and passive liveness, geofencing and an HMAC-bound location token — runs on commodity hardware with no GPU. Published with a full threat model, attack tree and a candid residual-risk analysis.
Commercial builds.
