You're scaling fast, your .NET backend is buckling, or your architecture decisions are slowing down every sprint. That's where I come in. I'm a Principal .NET Architect with 25 years building production systems that don't break under pressure — high-concurrency APIs, distributed microservices, cloud-native platforms on Azure, and the CI/CD pipelines that ship them reliably. Recent results: → Redesigned a booking platform codebase — 35% faster response time in production → Reduced a vendor onboarding workflow from 24 hours to 2 minutes through automated pipeline design → Architected Azure integration services syncing data across multiple enterprise systems with zero data loss using Service Bus, Cosmos DB, and serverless Functions → Built centralised NuGet packages for auth, logging, and exception handling — adopted across an entire microservices ecosystem What I bring beyond code: I own the full delivery lifecycle — architecture decisions, infrastructure as code (Terraform, Bicep), Docker/Kubernetes deployments, Azure DevOps pipelines, and production monitoring. I work independently, communicate clearly, and don't need hand-holding on technical decisions. Best fit for: ✦ .NET / ASP.NET Core backend systems that need to scale ✦ Cloud migration and Azure architecture ✦ Legacy .NET modernisation ✦ Microservices design and implementation ✦ Teams that need a senior technical lead, not just a coder I've worked across SaaS, ERP, and e-commerce platforms for clients in the Netherlands, Iceland, Germany, and UAE. If you need someone who can look at your system, tell you exactly what's wrong, and fix it — let's talk.
