What I'm looking for

I’m looking for a role where I can integrate AI/LLM capabilities into secure, scalable backend microservices. I want an Agile environment with strong engineering standards, CI/CD, and opportunities to lead through mentoring and code reviews.

I’m a Senior .NET Developer with 9+ years of experience designing and delivering scalable backend systems, microservices, REST APIs, and enterprise applications. I bring a strong background in C#, ASP.NET Core, Entity Framework Core, SQL Server, and cloud/DevOps practices, and I focus on building maintainable systems using Clean Architecture, SOLID, and DDD.

Right now, I’m focused on AI integration—building AI-powered features, intelligent automation workflows, and backend services that connect enterprise platforms with AI/LLM-based capabilities. I also emphasize secure API layers (authentication, authorization, validation, logging, and error handling), and I’ve led teams through code reviews, mentoring, Agile delivery, and cross-functional collaboration.
