I'm also an AI hobbyist, Web3 & Game Enthusiast. I have 2+ years of experience in actively exploring modern software engineering and building products that people love.
I specialize in building and maintaining software applications that are secure, scalable and performant regardless the tools and constraints around projects
Beyond work, I do AI research , learn competitive programming with maths and game dev, build a local open source community, mentor aspiring developers, create educational experiences and playing soccer :)
