What I'm looking for

I'm looking to build scalable Rails and React products, improve legacy systems, and apply AI-assisted, spec-driven engineering practices to reliable data-intensive workflows.

I've built and modernized high-throughput Ruby on Rails systems for Skydropx and FullStackLabs, improving logistics quoting latency by 20% while supporting 99.9% uptime and reliability.

At FullStackLabs, I modernized a critical React micro-frontend within a large Rails monolith. I designed decoupled Rails APIs, preserved backward compatibility, and improved component reusability across legacy systems.

I use Spec-Driven Development to define API contracts, data schemas, and edge cases before implementation. I also use Claude and GitHub Copilot to draft specifications and generate RSpec and Jest test suites that reduce technical debt and accelerate delivery.

Across roles at Michelada/Arkusnexus, Yuxi Global, AGS, BoostCoders, and HomeParte, I've delivered Rails and React features, integrated third-party APIs, maintained legacy billing and authentication systems, led developers, and supported cross-functional teams.
