Senior full-stack .NET engineer delivering scalable cloud-native web applications and APIs.
What I'm looking for
I am a senior full-stack engineer with deep expertise in .NET (C#), modern JavaScript/TypeScript front ends, and cloud-native architectures across Azure, AWS, and GCP. I have led cross-functional teams, modernized legacy systems, built microservices and CI/CD pipelines, and delivered production-grade solutions in Healthcare, Education, Finance, E-Commerce, and security-focused systems.
My work includes designing scalable microservices, optimizing database performance, implementing automated testing and security scanning, and deploying containerized applications to Kubernetes. I mentor junior engineers, build data and ML pipelines, and prioritize reliability, performance, and secure architectures that drive measurable operational improvements.
