What I'm looking for

I am seeking a role building scalable SaaS or enterprise systems where I can lead backend design, drive cloud-native practices, and contribute to CI/CD and performance optimizations in a collaborative Agile team.

I am a Senior .NET Full Stack Developer with 4+ years building scalable SaaS ERP and billing applications using .NET MVC/.NET Core, C#, RESTful APIs and Angular. I deliver high-quality solutions focusing on performance, integrations (payments, SMS/WhatsApp, email), and cloud-native practices such as Docker, Kubernetes and Azure.

I have maintained and enhanced ERP systems across major modules, implemented Clean Architecture and DDD, applied TDD and asynchronous programming for high-load areas, and collaborated in Agile teams to produce maintainable, testable code and CI/CD pipelines.
