Sri LankaWhat I'm looking for
I’m a Senior Software Engineer with 4+ years of experience designing and developing scalable enterprise applications, with a strong focus on Backend .NET (ASP.NET Core, Web API, Entity Framework Core) and modern frontend React. I build RESTful APIs and modular architectures (Modular Monolith / microservices) using reusable components and industry best practices, and I’ve integrated third-party APIs, authentication systems, and payment gateways to deliver secure and maintainable systems.
I work end-to-end across SDLC in Agile/Scrum—optimizing Microsoft SQL Server performance, improving application efficiency, and supporting production issue resolution. I also contribute to cloud delivery on Microsoft Azure with Azure DevOps and CI/CD pipelines, strengthen code quality through code reviews and mentoring, and apply AI tools (Claude, ChatGPT, Gemini) to accelerate development workflows.
