What I'm looking for

I’m looking for a role where I can build and optimise full-stack systems—especially REST APIs, microservices, and distributed architectures—while owning production reliability, RCA, and continuous delivery in an Agile team.

I’m a Full Stack Software Developer with 5+ years building scalable enterprise applications in banking and financial services. Currently, I’m a Senior Software Developer at S&P Global supporting SEB Bank, where I build robust REST APIs and microservices to cut response time by 30% through optimised architecture and async processing.

Previously, I worked at S&P Global as a Software Engineer / Associate Software Engineer, delivering Java web applications, performance tuning, and reusable encode-decode tooling that reduced database text length by 80%. I also strengthen reliability with 300+ unit and integration tests (90%+ coverage) using TDD practices, lead root-cause analysis to reduce recurring incidents by 40%, and bring an Agile/SAFe approach backed by an MSc Advanced Computer Science (Distinction) from the University of Birmingham.
