About Me

I'm a 20-year-old solo builder and developer, driven by a lifelong curiosity for technology that started when I was 8. I'm self-taught, with a passion for creating tools that solve real-world problems.

My expertise lies in building Open-Source dev tools, integrating AI into practical applications, and developing full-stack, privacy-first products from scratch.

Looking to build profitable, privacy-focused tools & collaborate with hackers.
