Full-Stack & Mobile Developer with 6+ years of experience turning ambitious product ideas into production software that scales. I specialize in TypeScript, React, React Native, Node.js, and AWS — building everything from customer-facing mobile experiences to serverless backend infrastructure that holds up under real traffic.

Over the past six years I've shipped features used by 100K+ monthly active users, architected component libraries adopted across multiple teams, and cut infrastructure costs while scaling systems 10x. I've worked across entertainment, fintech, and SaaS — building checkout and payment flows for 10M+ customers at Cinemark Brasil, enterprise platforms managing $500M+ in assets at GCB Investments, and AI-integrated product features at Airtable.

What drives me is the intersection of clean engineering and measurable business impact: every system I build is judged not just by whether it works, but by what it moves — load times, conversion, reliability, cost. I also care about the people I work with, having mentored 5+ junior developers and helped introduce testing and code-review standards that outlasted my time on those teams.

Currently open to full-stack and mobile opportunities — remote, hybrid, or on-site.
