What I'm looking for

I'm looking to build and scale cloud-native and AI-powered products, lead cross-functional engineering teams, and deliver reliable systems with strong observability, security, and automated quality practices.

I've built partner-embeddable booking products at Plusgrade, including a React and TypeScript microfrontend that increased upgrade-service access by 30% and auction bids by 5%. At SAP, I led a six-developer, two-QA migration from legacy Java and frontend technology to Java 21, Spring Boot, and Angular.

I'm currently building AI-powered features at Persistent with Python, FastAPI, Angular, RAG workflows, prompt engineering, and Langfuse evaluation. Across fintech, travel, enterprise software, and consulting, I lead delivery from architecture through deployment, with a focus on event-driven systems, AWS infrastructure, observability, testing, and secure cloud networking.
