Applied AI Full-Stack Engineer
Ten years shipping software. The last few: taking AI-enabled products
from zero to production in small startup teams — usually as the only engineer in the room.
Primary developer on the MVP of a health-fintech platform for seniors. I work directly with the founders and ship weekly.
- LLM document pipeline — uploaded medical records (photos, PDFs, insurance cards) parsed into structured data with Reducto
- Event-driven AI workflows — background parsing, retries, and long-running jobs with Inngest on AWS
- Accessibility-first frontend — Next.js 15 / React Aria, built to WCAG AAA for users aged 60+
- AI-native process — spec-driven development with Claude Code; how one developer keeps startup velocity without the tech debt
| Project | What I did | |
|---|---|---|
| 🎓 | ProfeIA 2024 – now · solo build |
AI exam-prep platform for Chilean teachers preparing the national ECEP certification. Adaptive quizzes with per-question AI feedback (OpenAI + Claude APIs), progress analytics, payments. Next.js 15 · Prisma · Supabase. 2,000+ teachers reached. |
| 🤝 | Marapod (The Fizzy LLC) 2024 – 2025 · sole developer |
Multi-tenant fundraising SaaS for parent-teacher associations, built zero-to-one: architecture, auth, Stripe Connect payouts, role-based access. From a non-technical founder's vision to a shipped product. |

Fundraising platform: Next.js migration, design-system modularization, Mixpanel instrumentation tracking 100k+ daily events. |
| 🏦 | Accenture Chile 2014 – 2022 |
Core-banking migrations for Banco Itaú and BancoEstado. Led a team of five through a DB2 migration spanning 1,500+ components with zero downtime. |
| 🌐 | Freelance 2023 – 2024 |
70+ SME websites (performance, SEO, accessibility), including Campo Maitén — real-estate site with interactive plot map and CRM integration. |
I build AI products and I build using AI — that distinction matters.
