Senior full-stack dev, team lead, CTO, spent over two decades architecting and building distributed systems, client-server software in C++ and Java to websites in Python/Django/JS to data processing backends to API servers in Go to mobile app code in C++ again.
Coding, analyzing requirements, managing, testing, marketing – been there, done that, failed at least once at every single one.
