What I'm looking for

I’m looking for a role where I can build end-to-end cross-platform features, improve scalability and maintainability, and apply cloud technologies and automation to boost developer productivity through solid CI/CD practices.

Software Engineer & Full Stack Developer with experience building scalable cross-platform applications for mobile, tablet, and desktop environments using Flutter and React Native. At GridSpark Solutions, I developed and delivered a Restaurant Management System (RMS), designing application architecture, business workflows, API integrations, billing systems, and customer management features. I also built a robust printer communication layer with automatic device discovery, reconnection, and billing hardware integration to improve operational reliability. Previously, I led the end-to-end development of a quick-commerce platform, architecting the frontend from scratch, integrating backend services and real-time features, and managing a team of four developers to deliver production-ready solutions.
