I build secure, high-throughput microservices that move real money for real people — and occasionally publish research on antimicrobial resistance for fun.
I'm a backend engineer with 5+ years of experience designing and scaling secure, high-throughput microservices across fintech platforms. I led the migration of a monolithic finance system to microservices — lifting performance by 78% and powering payment, invoicing, and discount flows for 40K+ real-time transactions. Outside of production systems, I've co-authored research on genomic epidemiology and antimicrobial resistance.
