What I'm looking for

I'm looking to build scalable backend and cloud-native enterprise systems, owning API design, security, performance, and reliable delivery while contributing technical leadership and mentoring.

I lead backend architecture at Epazz Inc., building scalable enterprise platforms with C#, .NET, REST APIs, and AWS/Azure. I own API security, multi-tenant service design, performance, and deployment readiness.

Previously at Mhouse Business Solutions, I developed services for retail POS, inventory, and analytics workflows, including secure Stripe, Razorpay, and PayPal integrations. I also improved real-time synchronization and database performance across SQL Server and Oracle.

I've delivered Laserfiche integrations at TCS, Tracker and Intercom integrations at Joblogic, and HRMS modernization at AutoSoft Dynamics. I bring 5+ years of enterprise backend delivery, production troubleshooting, CI/CD automation, and technical mentoring.
