Message

At FOO, I led the backend integration between core banking systems and the FOO platform via WSO2. I also built a K6 and Grafana load-testing framework that cut latency by 29%.

At IBC Solutions, I supported development of Finastra's Fusion Corporate Channels across four Gulf countries, building and optimizing Spring Boot APIs and Angular modules. I’ve also built a live booking and operations platform for a Lebanese padel business and contributed to an automated attendance system that ranked third in its capstone competition.
