What I'm looking for

I'm looking to build and modernize end-to-end enterprise applications, working across backend architecture, data, and responsive user experiences within collaborative agile teams.

I've built and modernized enterprise applications at Retro Rabbit, including credit, decisioning, healthcare, and HR platforms. My work spans Angular, C#/.NET, Java Spring Boot, PostgreSQL, secure 2FA flows, framework migrations, and production support for high-impact financial systems.

I'm currently supporting Standard Chartered Bank's enterprise payment systems, monitoring transaction processing suites, investigating failed batches, and helping resolve incidents while protecting business continuity and data integrity. I enjoy bridging robust backend architecture with responsive, practical user experiences.
