Engineering Team Lead & Backend Systems Expert

20+ years building and leading backend systems across fintech, AI & media, healthcare IoT, energy, defense, and gaming. Former CTO. Polyglot engineer fluent in 8+ languages who picks up new stacks fast when it counts.

About

I'm an engineering leader with over two decades of experience spanning the full stack — with my deepest roots in backend architecture, REST API design, database performance, and DevOps infrastructure. I've worked at every scale: as an individual contributor building systems from scratch, as a team lead managing eight engineers across timezones, and as a CTO taking a product from zero to production.

My career spans an unusually wide range of industries — fintech at Bloomberg and E*Trade, social payments at Tilt (5M+ users), healthcare IoT at NimaSensor, AI & media automation at UpResTech, energy sector voice platforms, defense simulation, and gaming. That breadth means I adapt quickly: I've consistently been handed new domains and new stacks and delivered.

I'm a polyglot engineer. I've shipped production code in TypeScript, Python, Go, Perl, Java, C/C++, and Erlang. When a role needs me to pick up a new language or framework fast, that's not a risk — it's something I've done repeatedly throughout my career and genuinely enjoy.

I lead by staying close to the work. I do architecture and code reviews, mentor engineers, collaborate with stakeholders to scope and estimate, and I still write code. The best engineering leaders stay technical — I believe that and try to live it.
