Hey, I am Abdelkader Ould Hennia

engineering, databases, and systems. always building.

I am a Backend Engineer who thrives on technical autonomy and performance engineering. Over the past two years, I have focused heavily on the mechanics of backend infrastructure—specifically optimizing relational database queries (PostgreSQL/MySQL), designing asynchronous event-driven architectures (Redis Pub/Sub), and building fault-tolerant APIs. What sets me apart is my approach to problem-solving: I don't just write functional code; I benchmark it under load, analyze execution plans, and ensure systems remain reliable under high traffic. Whether working with Go, Node.js, or containerized Docker environments, I take full ownership of the lifecycle from architectural design to deployment, I work remotely, take a piece end-to-end, and prefer decisions written down to decisions remembered.

Projects

Food Delivery System (Go + PostgreSQL + Next.js + Docker + Redis)

A production-oriented food delivery platform designed to connect customers, restaurant owners, delivery drivers, and system administrators. The application allows customers to discover restaurants, browse menus, place orders, make payments, and track deliveries. Restaurant owners can manage their restaurants, menus, and orders, while delivery drivers can manage assigned deliveries and update order statuses.

Shortly URL Shortener (Express + PostgreSQL + Next.js)

I built this as a complete, production-style example of a small backend service: a REST API with real authentication, a normalized PostgreSQL schema, rate limiting, and a thin Next.js frontend that consumes the API like any other client would. There's no ORM magic hiding what's going on — the data layer is plain SQL through pg, so it's easy to read exactly what every endpoint does to the database.
