What I'm looking for

I’m looking for a Senior/Tech Lead role where I can modernize .NET platforms, design scalable APIs and distributed workflows, and improve performance and production reliability—ideally with autonomy, cross-functional collaboration, and mentoring.

I’m a pragmatic, results-driven Senior Software Engineer with 10+ years of experience building, modernizing, and scaling enterprise software platforms across Europe and North America. I specialize in .NET platform modernization, API design, distributed workflow systems, and performance optimization for high-traffic SaaS serving hundreds of thousands of active users.

In my current role, I lead modernization and architecture planning alongside Engineering Leadership and Product Management, guiding monolith decomposition while keeping platforms stable. I’ve delivered a dual-track modernization strategy—moving from legacy .NET 4.5 to .NET 4.8.1 and building a modern .NET Core 8 + Blazor, microservices replacement in parallel—while mentoring junior engineers through rigorous peer review.

I also architected configurable workflow orchestration using Elsa Workflow Engine, turning hard-coded operational flows into dynamic, visual automations that non-engineering teams can configure. From production operations and hotfix execution under pressure to CI/CD reliability and database/performance tuning, my focus is delivering dependable business outcomes while continuously improving system scalability.
