Founding Product Engineer | AI-Native Builder

Remote-only · Mexico (CST/EST)LinkedInTwitter/XPortfolioGitHub

Summary

I ship 0-to-1 products solo - AI-native and fast, turning vague ideas into production architecture and a working app, not a demo. I currently run my own product (CrewTask) end to end: vision, architecture, code, quality. 15+ years in analytics and QA before that, so failure-mode thinking is baked into how I build. Honors degree in Mathematics & Economics. Disciplined systems, early failure detection, relentless execution.

Seeking Founding Product Engineer / AI Product Lead - or a build-heavy Growth / Automation / Forward-Deployed AI Engineer role - at a funded pre-seed/seed startup. Remote-only, based in Mexico (CST/EST) - set up as a contractor via Deel, so hiring is zero-friction for US/EU teams: no relocation, no visa sponsorship. Salary + equity.

What I Built

Founding Engineer-CrewTask V2 (AI-Powered Family OS)Nov 2025 - Present
Solo-built mobile app in 3 months part-time (nights, weekends, two kids + full-time job): React 18, TypeScript, Supabase, Capacitor. Multi-tier AI task parsing (Gemini cascade), native voice STT (OS / Web Speech with Gemini fallback), offline-first sync, multi-tenant architecture with RLS. My role: architect, product designer, quality gatekeeper, prompt engineer. Now live in Google Play open testing. Portfolio

Also shipped solo via AI orchestration: an AI research agent (Python + Playwright + LLM), a Next.js health-data app (scaffold), and a productized React/TS CI/CD release kit - stack-agnostic, output over keystrokes.
