ASP.NET Core Case Studies
Real-world ASP.NET Core backend systems I’ve designed, modernized, and scaled in production environments — with a focus on performance, reliability, and long-term maintainability.
What these case studies represent
- ✔ Production systems serving real users — not demos or sample projects
- ✔ Backends operating under high traffic, revenue pressure, or operational risk
- ✔ Work performed on live systems without disrupting ongoing business
- ✔ Long-term architectural improvements, not short-term patches
While every engagement is unique, the examples below highlight recurring patterns across high-traffic platforms, revenue-critical SaaS products, and legacy .NET systems transitioning to modern ASP.NET Core architectures.
High-Traffic Shipping Platform (EU)
Modernized a legacy .NET shipping platform handling thousands of daily international shipments with complex carrier integrations.
- Focus: ASP.NET Core migration, API reliability
- Tech: ASP.NET Core, SQL Server, Dapper, REST APIs
- Impact: 70% reduction in failed shipments
Revenue-Critical SaaS Backend
Designed and stabilized backend services powering subscription billing and customer workflows for a growing SaaS product.
- Focus: Performance, fault tolerance
- Tech: ASP.NET Core Web APIs, background jobs, caching
- Impact: ~45% faster response times
Legacy System Modernization
Refactored a tightly coupled legacy application into clean, testable ASP.NET Core services with clear separation of concerns.
- Focus: Architecture cleanup, maintainability
- Tech: ASP.NET Core, layered architecture, REST
- Impact: Faster delivery, lower defect rate
