What I'm looking for

I seek senior engineering roles where I can architect scalable, secure cloud-native systems, lead teams, and drive modern CI/CD and observability practices in a collaborative, security-conscious environment.

I am a results-driven .NET engineer with ten years of experience building and modernizing high-scale, secure full-stack systems using .NET (Core, 6/7/8), C#, and modern cloud platforms. I have led migrations from legacy .NET Framework to microservices, implemented DDD/CQRS patterns, and improved performance and reliability across APIs, databases, and distributed systems.

I have delivered end-to-end solutions spanning backend architecture, front-end interfaces (React, Angular, Blazor), CI/CD, infrastructure as code, and observability while mentoring teams and driving secure SDLC practices. My accomplishments include substantial DB performance gains, reduced response times through async refactoring, and successful multi-environment cloud deployments with strong security and compliance focus.
