Senior Software Developer & Web Team LeadChris Nohall
I build Bitcoin payment infrastructure at Blockonomics and privacy-focused tools for the open web. Currently based in South Korea.
The short version
I lead the web team at Blockonomics, where I architect Bitcoin payment infrastructure that handles thousands of transactions daily. My day-to-day involves scaling React/TypeScript frontends, hardening Python/PHP backends, and ensuring everything stays secure in the high-stakes world of crypto.
I don't just write code; I build tools that solve my own frustrations — like Chrome extensions that automate CRE data entry or privacy-focused temp mail services. I care about shipping software that's actually useful, not just technically impressive.
