QA Engineer at Amazon · Founder of Elyxis & I'm Okay · AI-native builder
I build honest consumer products — and I test everything. By day I do quality engineering for Amazon's Appstore & Fire TV; nights and weekends I've built two products end to end, solo, with AI agents as my pair-programmers.
🧪 Elyxis — A/B testing for humans → elyxis.app
n-of-1 self-experimentation: AI designs a rigorous protocol for one change — magnesium for sleep, matcha instead of coffee — you answer one thirty-second question a day, wearables fill in the confounders, and a Bayesian engine returns an honest verdict, including "no clear effect" when that's the truth.
~1,800 automated tests · 6 red-team passes (OWASP Top 10 2025) · 6 ecosystem audits · first live verdict — Jul 2026 · YC F2026 applicant · launching in weeks
🟠 I'm Okay — family safety check-ins → imokay.in
Confirm you're okay on a schedule; miss it, and your trusted contacts get told. No countdowns, no tracking, no panic — reassurance, not surveillance. 40 languages · exactly-once alert delivery · a fully native Kotlin/Compose Android app, because the alarm has to fire anyway. In final build.
YC's Paxel analyzed one month of my Elyxis build sessions: 388,577 lines · 604 commits · 147 sessions · 184 hours · a 22-day shipping streak — and profiled me as an "architect-controller": the agents produce, I decide.
Toolchain: Claude Code (daily driver) · Antigravity · Kiro · Claude Design · 4 self-authored AI skills · an Obsidian second brain that feeds itself · gitleaks + bearer on every commit.

For the past 1.5 years, every line I've shipped has had an AI agent in the loop. I'm not going back — I only want to work AI-native.
