Work Experience

Founder / Full Stack Developer - B2B proxy since 2020

Helping clients build their ideas by developing & hosting custom software solutions. I’ve worked with clients of all sizes - startups to enterprises - across various industries, technologies, and countries.

I usually do backend, infrastructure and frontend. I especially enjoy building AI-powered tools, blockchain-based systems, cloud-native software, and anything else that pushes the limits of what’s possible.
