/ About

I build software that simplifies complex systems into intuitive, high-performance products. As a Full-Stack Engineer, I design scalable backend architectures, APIs, and data models while delivering fast and reliable web and mobile experiences using Node.js, Python, React, React Native, and Rust.

My work spans blockchain, fintech, and Applied/Generative AI, with hands-on experience building Retrieval-Augmented Generation (RAG) applications, AI-powered workflows, Bitcoin wallet infrastructure and Lightning Network integrations. I enjoy solving problems where scalable systems, decentralization, and intelligent automation come together.

Outside of engineering, I spend time playing tennis, reading, coffee brewing, contributing to open source, and exploring different countries and cultures.
