Overview
Engineering internship in Beirut, Lebanon focused on improving a legacy Java desktop application used for internal workflows.
Worked across UI logic, database operations, and performance bottlenecks while collaborating with senior engineers.
What I built
Extended the Java desktop application by improving database operations and UI logic to support smoother internal workflows.
Added safeguards and cleaner flow handling to reduce friction in day-to-day usage.
Performance improvements
Improved runtime by ~25% by introducing multithreading to parallelize long-running tasks and reduce bottlenecks.
Identified slow paths, separated work into parallelizable units, and ensured UI responsiveness during heavy operations.
Maintenance & debugging
Debugged and refactored legacy modules with senior engineers to improve maintainability.
Reduced recurring issues by cleaning up fragile logic, simplifying modules, and improving code readability.
