Part of the E-Payments Acceptance Team, Responsible for developing and maintaining the Backend of the POS (Point of Sale) device, which handles critical transaction logic and integration with variouscompanies, banks, and other organizations.Implemented new integrations and business requirements, stabilizing the system during a challengingtransition period after the departure of the previous team.Collaborated closely with a vendor and internal teams to resolve major production issues, resulting in an approximately 90-95% overall improvement in system stability and a significant reduction in downtime frequency and duration.Discovered and documented previously unclear areas, including undocumented code and the internal flow of business logic in the codebase (e.g., how sale transactions are processed), and assisted in documenting newly introduced strategies to help the team understand and reference them more efficiently.

Part of the Red-sea Team, Responsible for developing new features and maintaining existing features onRed-Sea Ports Environments.My role involved resolving production issues and implementing new features corresponding to newbusiness requirements.Contributed to the development and maintenance of new features for Red-Sea Ports Environments,including the integration of tourism yacht services, a large-scale project under the interest of the Ministry of Transportation, and the implementation of QR code ticket scanning, which significantly improved customer satisfaction, earning a thank-you letter from the management at Port Adabia.Resolved approximately 10 to 15 production issues, including business change requests and error fixes, and optimized the codebase by applying the Single Responsibility Principle. This refactoring untangled complex logic within a single method, resulting in improved debugging, enhanced clarity, and better maneuverability and control through decoupled logic.Contributed part-time for 3 months to the development of a new feature for the Ministry of Justice,working alongside my main responsibilities at ISFP. Although my involvement was limited toimplementing part of the feature due to time constraints, I demonstrated the ability to manage dualresponsibilities effectively.
