Full Stack Developer

React & Next.js · Node.js & Serverless · AWS · Fintech & Blockchain

I’m a Full Stack Developer with 7+ years of experience owning features from zero to production—React and Next.js on the frontend, microservices and serverless backends on Node.js, and AWS (EC2, Lambda, Amplify, Cognito) in production.

I’ve led delivery for small teams, shipped blockchain and fintech products, and built data-intensive systems that pull from multiple sources and land in audit-ready workflows. I take individual responsibility for shipping while helping teammates move faster.

Outside of code, I recharge by traveling, exploring nature, and spending time with my kid—my best source of inspiration.
