What I'm looking for

I seek roles where I can build scalable AI and Web3 products, lead technical efforts, work with clean architecture and strong testing, and ship production-ready user experiences.

I am a full-stack engineer with 7+ years of experience building AI-powered assistants, real-time blockchain-integrated web apps, and production-ready interfaces using React, Next.js, Python, and Go. With an MSc in Applied Mathematics, I combine strong analytical thinking with fast execution to deliver elegant solutions and great UX.

I have led platform modernizations, implemented voice-based LLM agents with RAG backends, and built distributed bioinformatics pipelines; I prioritize clean architecture, reliable testing, and scalable deployments while bridging AI and Web3 technologies.
