What I'm looking for

I seek roles where I can architect scalable .NET systems, lead engineering teams, drive microservices adoption, and deliver measurable performance and reliability improvements.

I am a results-driven Senior Software Engineer with over five years of experience delivering solutions across Healthcare, E-commerce, and Financial Services.

I specialize in the .NET Framework and .NET Core, architecting high-performance backend systems and leading cross-functional teams to implement scalable microservices and maintainable monoliths.

My work has included leading a card portal system, integrating web services to post 10k+ transactions, and optimizing heavy queries from 2 minutes to under 15 seconds; I also implement CI/CD to accelerate delivery and reduce errors.

I emphasize clean architecture, domain-driven design, and robust data structures to build reliable systems, mentor teams, and drive initiatives that deliver measurable, transformative outcomes.
