I lead .NET teams building scalable enterprise SaaS and web platforms.
PakistanWhat I'm looking for
I lead development for Contour Software's InReach CEMS multi-tenant SaaS platform, staying hands-on while mentoring developers, reviewing code, and improving engineering practices.
I've migrated 10+ classic e-commerce catalogs into responsive multi-tenant experiences using reusable Stencil.js components, accelerating onboarding and improving maintainability. I also delivered an end-to-end Stripe stored payment solution and built a GitHub Copilot Custom Agent to automate catalog-migration template generation.
At Systems Limited, I developed 90% of the backend for TransRe's TIRS Web Cash migration, helping move a PowerBuilder desktop application to microservices and delivering its initial development within six months. For ESS Plus, I built 30+ REST APIs, improved API response times by 40%, and supported a global workforce of 8,000+ users.
I've led Agile delivery, CI/CD deployments, technical design, production support, and cross-functional collaboration across HR, banking, reinsurance, and cloud-migration products. My work spans .NET, C#, REST APIs, Angular, React, Azure, SQL Server, and AI-first development workflows.
