What I'm looking for

I seek a senior engineering role building cloud-native, secure, and maintainable enterprise systems with strong DevOps and team collaboration.

I am a Full Stack Software Engineer with 10+ years building and modernizing enterprise web applications using C#, .NET (Core + Framework), JavaScript/TypeScript, SQL Server, and cloud platforms—particularly AWS. I deliver end-to-end solutions across front-end, back-end, database, and DevOps: REST APIs, microservices, serverless workflows, CI/CD pipelines, IaC, containers, and production support, with measurable improvements in performance and reliability.

I excel in legacy-heavy environments while transforming systems to modern UI and cloud-native services, having reduced release effort, improved API responsiveness, lowered operational costs, and cut recurring defects through automation, refactoring, and strong documentation. I prioritize clean, maintainable, and secure code, strong documentation, and reliable delivery within Agile teams.
