GoFresh is a Kuwait-based online grocery platform serving both web and mobile users. The goal was to deliver a complete commerce system with a shared backend that could reliably support catalog browsing, ordering, and user activity across platforms. I worked on the full development lifecycle, covering backend services, frontend integration, and mobile backend support. On the backend, I designed and integrated REST APIs for product catalog management, pricing, cart operations, order processing, and user authentication. The APIs were structured to be reusable and were consumed by both the web platform and a Flutter-based mobile application. From a technical perspective, I focused on backend reliability and scalability. This included improving API response handling, ensuring consistent data models for products, users, and orders, and managing authentication and session flows securely. I also worked on optimizing API calls to reduce unnecessary requests and improve performance under load

Growcase is a real-time online gaming platform with live user interaction and third-party game integrations. The goal was to stabilize the production system and scale backend services to support concurrent users. I worked as a full-stack developer with a strong focus on the Node.js backend. I handled production deployment on DigitalOcean, domain and SSL setup, and post-launch stabilization. I optimized REST APIs, improved WebSocket handling for real-time gameplay, and stabilized MongoDB connections under load. I also integrated third-party game provider APIs and improved deployment safety through version control practices. The platform was stabilized to handle higher traffic with improved performance and reliability.
