Software Engineer · Ruby on Rails & React · Backend-Focused Full-Stack
Backend-focused software engineer with 5+ years building and scaling mission-critical systems across EdTech, FinTech, and industrial sectors. I specialize in Ruby on Rails and React — designing systems that stay reliable at real-world scale, from high-frequency data pipelines to compliance-critical platforms (GDPR, LGPD, CCPA). Over the last two and a half years I've partnered with US companies and international teams, owning the full lifecycle from requirements to production support.
Engineering writeups:
- Building Iron Cars Shop: what actually goes into an AI-powered marketplace — eager loading, deferred-join pagination, and an AI agent that never writes to the database on its own.
- Building Kinko: A Double-Entry Ledger, the Hard Way — how I designed a financial core with an immutable ledger, a domain layer decoupled from Active Record, and idempotent Stripe webhook processing.
