About

I am a senior full-stack and systems engineer with deep expertise in TypeScript, Rust, blockchain architecture, distributed systems, and high-performance backend development. Over the past years, I have built and led multiple products end-to-end, including decentralized platforms, real-time communication systems, no-code analytics tools, and algorithmic trading technology.

I have founded and directed startups, managed multidisciplinary teams, and delivered more than 30 projects across web, mobile, and Web3 ecosystems. My experience spans smart contract development, scalable cloud infrastructure (AWS, Docker, Kubernetes), and modern frontend frameworks such as Vue, React, and TypeScript. I bring strong architectural judgment, self-management, and product ownership, turning complex technical challenges into reliable production-ready solutions.
