Hi, my name is

Hassan Ahmed.

I build systems that scale.

Senior Software Engineer with 7+ years shipping cloud-native microservices and enterprise banking platforms at Oracle, Bank of New York, and Bank of America. I turn complex problems into clean, production-grade code.

01. About

About Me

Senior Software Engineer at Oracle America, where I architect cloud-native microservices platforms — building distributed backends, JWT-secured REST APIs, and automated multi-tenant onboarding pipelines that handle data at scale.

At Bank of New York I contributed to an enterprise AI platform used by 20,000+ employees and engineered a real-time transaction anomaly detection system for risk and compliance teams. At Bank of America I scaled a disaster recovery platform from 2,000 to 5,000+ users and led MFA integration across the organisation.

M.Sc. Computer Science. I write technical articles and mentor engineers.
