Evidence Hub — every claim, proven

See the real proof behind every product decision.

I'm a Technical Product Manager and Ph.D. engineer. I design, build, secure, and test real software products — completely on my own. Every decision is explained clearly on this site, so you see proof, not just claims.

This isn't a portfolio of screenshots. It's structured like the internal docs I actually write for my own products — problem framing, architecture diagrams, trade-offs considered and rejected, security control matrices, and test coverage breakdowns. If you already know what you're looking for, skip straight to a category of evidence instead of reading a narrative.

Flagship products

Two systems, built and shipped solo

Each case study covers the problem, the architecture, the trade-offs rejected, the security posture, and the test coverage — not just the outcome.

Background

8+ years in EdTech, then a Ph.D., then two solo-shipped products
