⭐ 80+ Projects Delivered | $70K+ Earned | 100% Job Success | 10 Years on Upwork Not just a developer. A technical partner who gets your product shipped — and leaves your team able to own it after I'm done. I work with founders, CTOs, and product teams building .NET backends that actually scale. From greenfield SaaS to legacy ASP.NET migrations to microservices rewrites — I've done it across Healthcare, Cybersecurity, SaaS, Travel & Hospitality, and EdTech. 🔧 Sound familiar? • Your SaaS backend wasn't built to grow — and it's showing • Legacy ASP.NET app drowning in technical debt • APIs are slow, DB queries are timing out, users are complaining • You need microservices but don't know where to start • Cloud costs are climbing with nothing to show for it 🚀 How I work: Discovery → Architecture → Build → QA → Deploy → Scale No hand-holding needed. You describe the problem, I own the solution end to end. 💻 Core Stack: → Backend: ASP.NET Core, C#, Web API, EF Core, Dapper → Frontend: Angular (2–18), React, Next.js, TypeScript → Architecture: Clean Architecture, Microservices, CQRS, DDD → Database: SQL Server, PostgreSQL, Redis → Cloud & DevOps: Azure, AWS, Docker, CI/CD, Hangfire → Auth & Security: JWT, OAuth, Identity Server, HIPAA-aware 🎯 I can plug in as: ✅ Senior developer on your existing team ✅ Tech lead owning architecture decisions ✅ Fractional CTO for startups without a technical co-founder Let's build something that doesn't fall apart at scale.
