Description

Thanks for stopping by. I’m Miguel San Martin, a Full-Stack Developer with over 8 years of experience building scalable and high-impact digital products.

I’m passionate about technology and love diving deep into projects—from designing system architecture and implementing features, to setting up CI/CD pipelines and collaborating across teams. I’ve worked on Uber-style mobility apps, betting platforms, e-commerce solutions, stock systems, and digital wallets integrated with internal PSPs.

Currently, I work as a Full-Stack Developer at a fintech, building a mobile app in React Native (with Expo and Zustand) and developing the wallet backend using NestJS, TypeScript, and broker-based architecture on AWS.

My stack includes: Node.js, React Native, Next.js, NestJS, Serverless (AWS), PostgreSQL, MongoDB, and more.

I’m always open to learning, sharing, and joining teams looking to build something great.
