I AM YOUSSEF
BACKEND SYSTEMS ENGINEER
Specialized in System Architectures, Scalable Monoliths, API Optimizations, and Database workflows.
I can help you with
System Architecture
Designing decoupled, domain-driven architectures and modular monoliths that maintain clean bounds, robust data flow, and long-term scalability.
API Engineering
Developing high-concurrency, well-documented RESTful APIs and real-time endpoints equipped with rate-limiting, secure OAuth, and JWT authentication.
Database Optimization
Structuring relational and NoSQL schemas, writing complex aggregations, configuring caching layers, and tuning query execution times down by up to 40%.
AI Integration & Devops
Building prompt engineering scripts, LLM integrations, and containerizing backend environments using Docker, Celery, and cloud-native workflows.
Turning my vision
into system logic.
Experience & skills
Recent projects
[SYSTEM] Checked 15 boards. 0 overdue.
Taskify
"High-Performance Task Management Platform"
Teams and individuals struggle to organize tasks, track due dates, and visualize workflows in an intuitive, hierarchical structure, leading to missed deadlines and productivity bottlenecks.
Designed a clean, decoupled system with MongoDB modeling nested board layouts for fast querying. Integrated automated cron jobs for due-date tracking and push notifications, and deployed the frontend/backend on Vercel and Render respectively.
Handling real-time state changes and nesting database queries efficiently without triggering N+1 database call anomalies. Solved by writing optimized aggregations and implementing selective MongoDB population.
