I build scalable full-stack products, from fintech transactions to enterprise HRMS platforms.

India

Message

I've shipped high-impact products at M-Files India, Mewurk Technologies, FirstConnect, and Carvewing, including an HRMS module generating $200K+ ARR and a fintech transaction platform handling $50M+ daily volume. I build scalable C# and ASP.NET Core services with React or Angular frontends, supporting up to 50K+ concurrent users.

I've improved API latency, cloud costs, release cycles, and engineering velocity through microservices, event-driven architecture, Redis caching, CI/CD, and reusable component libraries. I also lead product initiatives and mentor engineers on full-stack development, architecture patterns, and code quality.
