Frontend-utvecklare
En av Hazems mest anmärkningsvärda prestationer är att han designade en mikroarkitektur för det nederländska företaget Flipstream, som innehåller över 200 molnfunktioner byggda i Node.js (TypeScript) och Python. Detta system inkluderar ETL-processer, Stripe-betalningsintegration, autentisering mekanismer och mer. Under de senaste tre åren har det fungerat felfritt utan kundklagomål eller incidenter, vilket visar hans starka engagemang för kvalitet, tillförlitlighet och skalbar systemdesign.
Hazem har också utmärkta kommunikativa färdigheter och nästan modersmålsproficens i engelska, vilket möjliggör effektiv samverkan mellan team och intressenter.
