About
Product-minded engineering leader with a strong security foundation — five years in Information Security & Risk Management at Johnson & Johnson, then product ownership of the Innovative Medicine HCP portal across LATAM and CENCA. Today I lead Full Stack Engineering across a 25-initiative portfolio, 10 of them mine end to end. Integrating AI capabilities across the planning, build, test and release lifecycle produced US$1.2M in cost avoidance in the first seven months of 2026.
Founder and sole engineer of Meus Desafios, a live habit-tracking app on iOS and Android — and of the grounded conversational assistant on this site. I own product, mobile client, backend, billing and store releases end to end, which is where product ownership and hands-on engineering meet in one pair of hands.
AI-Assisted Engineering Practice
How the work gets done
The practice behind the US$1.2M — how AI is integrated across planning, build, test and release, and the bar agent-written work has to clear. Every mechanism below exists because of a failure it prevents.
- Specifications and agent instructions are version-controlled artifacts committed next to the code and reviewed like source, so the context an agent works from is owned and current rather than re-explained each session.
- Recurring workflows are packaged as reusable agent skills rather than re-prompted from scratch, so the same task produces the same shape of output whoever runs it.
- Agents run on scoped subtasks in isolated git worktrees, so parallel work cannot collide and every change stays independently reviewable.
- A reviewer agent audits the writer agent's diff before a human sees it — first output is never the output that ships.
- Agent changes clear the same gate as human ones: build, typecheck, lint and tests pass before review, and a person approves every merge.
- Headless runs handle the repetitive passes — migrations, codebase-wide sweeps, release checks — that do not need someone in the loop.

Key Responsibilities
- Led the team that took 1st place globally in the 2026 Hack4Health hackathon, Care Community theme.

Things I Build
Shipped and running
The app I founded and build alone. React Native and Expo on the client, Next.js and PostgreSQL on Vercel behind it, a Maestro end-to-end suite gating every release, and freemium billing behind the Premium tier. Tracks sleep, water, calories and exercise, with duels, private groups and weekly leaderboards.
