What I'm looking for

I seek a collaborative, growth-oriented fintech or software team where I can build scalable backend systems, expand into full-stack .NET responsibilities, and advance my cloud/DevOps skills.

I am a Junior .NET Developer with two years of hands-on experience building and optimizing backend financial systems using C#, .NET Core, ASP.NET, and SQL. At ErrandPay I designed and maintained RESTful APIs, implemented CI/CD pipelines with Azure DevOps, integrated AWS services for secure data storage and background processing, and contributed to a microservices-based fintech platform that improved system performance and transaction reliability.

I progressed from backend intern to developer, delivered production-ready features, wrote unit tests (xUnit/NUnit), and improved reconciliation and reporting efficiency while collaborating in Agile teams. I am eager to contribute my backend expertise, grow into a stronger full-stack .NET engineer, and help build scalable, secure financial applications.
