Message

At Imperial Solutions, I engineered a multi-tenant Gym Management SaaS spanning a web app, backend API, and mobile client, with secure access across six user roles. I also built a WhatsApp bulk-messaging engine and architected an event reservation API that prevents ticket overbooking under concurrent load.

Previously, I developed secure store-management tools at T-Mobile (USA) and built enterprise web platforms at Symmetry Digital, including an internal visual chatbot builder. At Zapdas Solutions, I built responsive dashboard layouts and integrated REST APIs.
