Youssef I.

Backend engineer specializing in Python — Django, FastAPI, and Flask — with production experience running live PHP/Laravel systems. I build backends that hold up under real conditions: event-driven microservices over RabbitMQ, REST APIs, background job pipelines with Celery, and data models across PostgreSQL, MySQL, and MongoDB. Recent work: • Designed a four-service event-driven microservices system (Django + Flask + FastAPI) communicating asynchronously over RabbitMQ with shared JWT auth — including diagnosing and fixing a silent message-loss path in a dead-letter exchange. • Built a Django REST ticketing platform using row-level locking to prevent overselling under concurrent checkouts, Celery Beat reclaiming abandoned holds, and Redis caching with signal-driven invalidation. • Owned 43% of a 960-commit Laravel backend on a five-engineer team — 30 models, row-level multi-tenancy via global scopes and 27 policy classes, and a queue-driven order pipeline. • Reviewed AI-generated Python solutions for a US enterprise client against correctness, repository conventions, and test coverage. Stack: Python (Django, DRF, FastAPI, Flask) · PHP/Laravel · PostgreSQL · MySQL · MongoDB · Redis · RabbitMQ · Celery · Docker · Git/CI I work full UK/EU business hours from Alexandria (UTC+3) and communicate in clear written English — five years of it in a UK-based operations role before I moved into engineering.
