Project details

Need a powerful backend for your app or SaaS platform?

I’ll build a clean, scalable, and secure REST API using ASP.NET Core (C#), Entity Framework Core, and SQL Server. The API will follow Clean Architecture principles, use JWT authentication, and be documented with Swagger/OpenAPI.

You’ll get production-ready endpoints — perfect for Angular, React, Flutter, or mobile frontends.

Senior Full Stack Developer for Real-Time SaaS Dashboard (Node.js + React + WebSocket) Asad was an outstanding addition to our team. His deep expertise in real-time architecture, especially with WebSockets, MongoDB, and Redis, made our logistics dashboard fast, scalable, and production-ready. He also helped us clean up our containerization setup and guided frontend improvements in React. Would absolutely work with him again!

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. Drop me a message.
