What I'm looking for

I’m looking to involve .NET/REST product and platform development, strengthen CI/CD and maintainability, optimize database performance, and grow teams in an Agile environment.

I’m a Software Development Group Manager who turns complex integration requirements into reliable .NET services. In my recent role, I contributed to post-acquisition integration of e-transformation products (e-invoice, e-archive), built Continuous Integration pipelines on Azure DevOps for .NET Framework applications, and reconstructed a unified codebase from evolving segments. I focus on maintainable REST implementations and dependable enterprise workflows using WCF, SOAP XML Web Services, Windows Services, and Quartz.NET.

In earlier experience, I was hired as a Senior Software Engineer and progressed through team leader, manager, and director responsibilities while leading software development teams. I led development and maintenance for B2B web/web service applications, back-office modules, payment module (virtual POS integrations), BI and reporting, and hotel product integrations, including third-party accounting integration APIs. I also drove query performance optimizations (complex queries/indexes on MSSQL Server) and delivered reporting using SSRS, while supporting orchestration through Hangfire and modern ASP.NET MVC/Web API and ASP.NET Core MVC/Web API stacks.
