I build the systems you never see — but always rely on.
Kafka consumers eating 1B+ daily events. YouTube billing for 2B+ users.
Backend is where the real work happens.

About Me

5+ years in the trenches at Google, Salesforce, and Walmart. My specialty is the stuff most engineers shy away from — high-throughput distributed systems, complex data pipelines, and backend infrastructure that has to work every single time, at scale.

I've shipped Kafka consumers processing 1B+ daily events, led teams that delivered $60M+ in new revenue, and optimized pipelines serving millions of warehouse units. The best systems are invisible — and I like building those.
