About Sajid
Senior .NET Architect | ASP.NET Core & MSSQL | Fintech & Healthcare
Faisalabad, Pakistan - 7:59 pm local time
✅ Principal Engineer & Engineering Manager
✅ Fintech, Healthcare & SaaS
I architect and modernize enterprise .NET systems: ASP.NET Core, C#, MSSQL, and cloud for companies in regulated industries where correctness, security, and auditability aren't optional.
Across 12+ years as a Principal Software Engineer and Engineering Manager, I've designed and shipped production systems for US companies in healthcare, edTech, and marketing, leading teams through the full cycle from PoC to Production to Scale.
Where I go deep:
🔹 .NET Enterprise Development: ASP.NET Core / MVC, C#, Web API, and MSSQL with clean, maintainable architecture. I've built regulated systems like a healthcare billing & coding platform (ICD/CPT validation, ASP.NET MVC, MSSQL): money- and compliance-sensitive software where every edge case matters.
🔹 Regulated & Fintech-Grade Systems: healthcare and financial software share the same bar: transactional integrity, audit trails, data security, and zero tolerance for silent failure. I build to it: validated workflows, role-based access, and fully logged, auditable operations.
🔹 Architecture & Team Leadership: as Principal Engineer I owned system design, code quality, and technical decisions; as Engineering Manager I've run delivery, release management, and mentoring. I can be your architect and run the build.
🔹 Modern Full-Stack & SaaS: React, Next.js, Angular, and Node.js for modern front ends and MERN/Next.js SaaS builds: multi-tenant architecture, RBAC, and secure REST & GraphQL APIs.
🔹 Cloud, DevOps & AI: AWS, Docker, and CI/CD with deployment automation. I ship and operate systems, not just write them. I also integrate practical AI (OpenAI/GPT, RAG-based knowledge chatbots) into enterprise systems when it adds real value.
What makes me different: most senior .NET engineers stop at the legacy stack. I architect and modernize the systems regulated industries depend on, and add modern full-stack and AI layers on top, without breaking what already works.
Recent work includes a healthcare billing & coding platform (.NET / MSSQL), an edTech learning platform (React / Next.js / Docker), and ongoing full-stack work for a US SaaS client.
I communicate clearly, set realistic timelines, and focus on business outcomes, not just code. Share your project goals and I'll give you an honest technical plan and a roadmap to production.
