Senior Software Engineer / Full-Stack · Cloud & DevOps

EmmanuelManana.

I build and ship the systems banks, fintechs, and energy providers run on — event-driven services in .NET and Java, the React and Vue frontends on top, and the Kubernetes pipelines that get them to production.

Legacy platforms in, event-driven services out — tested, automated, and running in production.

Senior Software Engineer with 6+ years delivering production systems across banking, fintech, energy, and enterprise platforms. I modernise legacy systems into event-driven microservices, own delivery end to end — C#/.NET, Java/Spring, React/Vue/Angular — and run the cloud CI/CD that ships it on AWS, Kubernetes, Argo CD, and GitHub Actions.

I'm known for shipping high-stakes features in agile teams, cutting operational cost through infrastructure optimisation, and raising engineering quality with automated testing and DevOps practice.
