Full-Stack Developer | Product Engineer

I build web products end to end: I design the API and data model, and build the interface with clear flows, responsive layouts and accessible components. On larger projects I run multi-agent workflows with tools like Codex, Claude, Grok or OpenCode: one agent implements, another reviews, and automated tests check the result.

I spent five years at Ford, HSBC and Aivo, and co-founded Rely and Acelera. I'm now looking for product engineering roles with a strong frontend focus.

Rely company formation dashboard with personal details removed

Rely

A live product where founders form a US company and receive the EIN and documents.

My part
Two developers with mutual code review. I lead product and engineering: one order model behind the founder dashboard, the operations queue and 6+ integrations.
What you can check
rely.business and sanitized screens; around 40 companies went through the dashboard.

Two physical Lemon Box enclosures showing the front display and green Lemon branding

Lemon Box

A desk display for Lemon that shows live crypto and stock prices.

My part
I wrote the ESP32-S3 firmware and integrations (Wi-Fi setup, market APIs, alerts, OTA), printed the enclosures and assembled the units. Joaquín (Ferced) modeled the enclosure.
What you can check
Photos of working units, public firmware with releases and the enclosure files.

LLM Local PDF

My offline prototype that turns sensitive Argentine legal PDFs into JSON for a person to review, without a hosted model.

My part
Python with Qwen2.5-7B on llama.cpp. Timeouts, retries, JSON repair and schema checks return a reviewable result or a clear failure.
What you can check
Public repository with setup, schema and tests. No measured accuracy benchmark.
