At DG Groups, I design and develop frontend, backend, and admin platforms for betting and gaming products. I’ve built real-time systems with live sports data and betting modules, integrated REST APIs and backend microservices, and added AI-powered features using OpenAI APIs and LLMs.

Previously, at Loma Technology, I developed applications serving 500K+ users, and at Getvital.in I worked on healthcare and e-commerce applications. My projects include Live Baccarat, a real-time betting platform, and 5Goal, a football analytics and prediction platform.
