Experience
Production-inspired Back End for Publishing Posts
https://github.com/RamiYahyaRY/mini-buffer-platform• Deployed on AWS across multiple Availability Zones with Docker, container orchestration, and load balancing for higher availability and scalability.
• Implemented scheduled publishing, audit trails, secure webhooks, application metrics, and integration testing for core publish flows.
• Used AI-assisted development throughout for planning and implementation, while still owning correctness, code quality, and testing.
Web CRM for Vehicle Insurance Compensation and Claim Management
It utilizes aggregated data from clients' native databases and creates a specialized hub for managing insured and accident files, introducing price offers on damaged vehicles by spare part vendors, and ensuring that each vehicle is compensated/fixed on time. The back end is built in Node.js and MongoDB.
Mobile App for Vehicular Accident Inspectors and Loss Adjusters
It is integrated with a mission-critical customer relationship management system for the country's largest vehicle insurance companies.
