Freelance Full-Stack & Mobile Developer

“Building MVPs and scaling apps with React, Node.js & React Native.”

I am a freelance full-stack and mobile developer with 10+ years of experience building digital products. I specialize in React Native, React.js, Node.js, and modern cloud stacks, helping startups and businesses turn ideas into reliable, scalable apps. My focus is on delivering fast, functional MVPs and long-term maintainable systems that blend thoughtful design with robust engineering.

I’ve had the opportunity to work on SaaS platforms, fintech apps, and consumer products for teams as well as several independent clients. Before freelancing, I worked as an Android and Node.js developer at agencies, experiences that shaped my foundation in building production-ready apps. For me, freelancing is about more than writing code — it’s about partnering with founders to validate ideas quickly, scale products efficiently, and create user-centric experiences.
