What I'm looking for

I’m looking for a remote, agile team where I can lead and build enterprise .NET systems—C#, ASP.NET Core, Azure, and microservices—partnering with US stakeholders to ship reliable APIs and modern web features.

I’m a Senior .NET Software Engineer with 16+ years of experience building and maintaining enterprise-grade web applications and APIs. I focus on dependable backend systems, clean architecture, and software delivery that teams can trust.

I’ve worked in fully remote, agile environments with US-based clients like Gorilla Logic, 10Pearls, and Knowfully. I’m comfortable collaborating across time zones and contributing through daily standups, sprint planning, and peer code reviews on GitHub.

My core expertise is C#, ASP.NET Core, Azure, and microservices architecture. I’ve led migrations from legacy monoliths to microservices, including re-architecting portals into multitenant MVC applications and delivering event-driven, REST API-based solutions.

I also bring practical experience integrating CRMs and enterprise platforms (Salesforce, Microsoft Dynamics CRM, Zuora, Sitefinity) and managing cloud delivery with CI/CD pipelines, Service Bus, Key Vault, and Application Insights. Whether leading technical delivery or building new features, I aim to ship robust systems with clear ownership and continuous improvement.
