I build backend systems that work the first time and keep working after I leave. My last client hired me twice. The first time to build a custom eSign platform from scratch. The second time — three months later — to extend it, because the original architecture was clean enough to grow without rewriting. That's the kind of software I build. 10 years of enterprise backend development. I've built: → A loan processing engine for a banking platform — retail and corporate lending workflows, credit decisioning APIs, multi-stage approval pipelines → A custom eSign web application — full design and development, then seamless feature expansion for a returning client → A serverless inventory management system on AWS (Lambda + DynamoDB + API Gateway + Cognito) → Clinical documentation systems handling care gap detection across 31 medical categories I specialize in the kind of backend work where getting it wrong is expensive: financial services, healthcare, compliance-heavy domains. Systems where you need someone who thinks about edge cases before they become production incidents.
