I help businesses rescue, modernize, and scale legacy .NET applications without disrupting ongoing operations. Most of my clients reach out when: - Their legacy system is crashing, slow, or insecure - Developers left and nobody understands the code - Compliance audits (HIPAA / PCI-DSS) are failing - The system can’t scale with users or business demand - They want to modernize without a risky full rewrite With 9+ years of experience, I’ve helped companies in Healthcare, FinTech, ERP, POS, and HRMS turn fragile legacy systems into secure, cloud-ready platforms used by thousands of users daily. ✅ What I Can Do for You - Stabilize and refactor legacy .NET / ASP .NET applications - Modernize WebForms or MVC apps into clean, scalable architectures - Migrate systems to .NET Core / .NET 6–8 and Azure - Fix performance bottlenecks and security vulnerabilities - Design compliance-ready systems (HIPAA, PCI-DSS, HL7/FHIR) - Build new systems the right way using Clean Architecture 💡 How I Work (and Why Clients Keep Me) - Clarity first - I break complex systems into simple, business-friendly plans - No surprises - Milestone-based delivery with clear progress visibility - Production-ready quality - Clean, maintainable, documented code - Post-delivery support - Free bug fixes for 1 week after delivery - Partner mindset - I challenge bad decisions and suggest better solutions 🛠 Core Tech Backend: C#, .NET Core 6/7/8, ASP .NET MVC, Web API Frontend: Angular, Blazor, Razor, WebForms, React Cloud: Azure, Azure Functions, Docker, Kubernetes Architecture: Clean Architecture (CQRS + DDD), Microservices Security: JWT, OAuth2, HIPAA, PCI-DSS Databases: SQL Server, PostgreSQL, Cosmos DB 📩 Not Sure Where to Start?
