I architect scalable .NET and Angular enterprise systems for high performance.
CanadaWhat I'm looking for
I’m a Senior Full-Stack Developer with 16+ years of experience architecting and delivering scalable, high-performance enterprise systems across European and North American markets. My deep expertise spans .NET Core/.NET 8, C#, Angular, and microservices architecture.
I specialize in legacy system modernization, Clean Architecture, and SQL performance optimization—turning complex requirements into production-grade solutions. In my recent work, I’ve developed and scaled ERP systems and delivered backend payment and operational modules for global enterprise operations.
I thrive in cross-cultural, distributed teams and bring hands-on technical leadership with prior team-lead experience across the full SDLC. At arades GmbH, I designed high-performance APIs integrated with Microsoft Dynamics, and I built a License Cost Calculator backend that improved data processing efficiency by 20%.
Earlier, I architected backend infrastructure for high-concurrency B2B flight reservation systems, increasing throughput with RabbitMQ message queuing and Redis caching. I’ve also led modernization of legacy WPF desktop applications to modern .NET architecture, and I optimized high-speed cheque scanning to raise QR code recognition accuracy from 10% to 80%.
