Data Science & ML Background: Before specializing in AI engineering, I spent 3+ years in data science - building NLP classification pipelines, geospatial clustering models, and end-to-end ML solutions for multinational clients at Artefact (MENA) and Innovum (Switzerland). This foundation means I don't just call APIs - I understand the models underneath. My process: 1. You describe your problem - I give you a technical plan within hours 2. We agree on scope, milestones, and deliverables upfront 3. I build iteratively with regular demos so nothing surprises you 4. I deploy to your cloud and hand over clean, documented code Trilingual: English · Arabic · French Message me your project - I'll respond within hours with a concrete plan, not a generic pitch.

I build backend systems that hold up under real load: APIs, async pipelines, data systems, and increasingly AI-enabled features, using Django, FastAPI, PostgreSQL, Celery, Elasticsearch, ClickHouse, Docker, and AWS. Recent work has focused on helping teams add AI/LLM capabilities to real backend systems, not fragile demos: multi-provider orchestration across leading LLM providers, cost-aware model routing, fallback handling, LlamaIndex-based RAG pipelines, pgvector for vector storage, and self-hosted deployment (Ollama, OpenWebUI) where privacy or predictable inference cost matters more than convenience. The main ways I can help: Python Backend and API development I build and improve Django, Django REST Framework, and FastAPI backends: REST APIs, database models, background workers, admin workflows, authentication flows, reporting features, third-party integrations, and deployment-ready services. AI/LLM Backend integration I help you add AI features to an existing product in a maintainable way — multi-provider orchestration, RAG-style retrieval, embeddings workflows, and prompt-driven features built with the same rigor as the rest of your backend. Data pipelines and search systems I've worked on distributed ingestion and indexing systems using Python, RabbitMQ, Celery, Elasticsearch, ClickHouse, and PostgreSQL — systems that collect, validate, process, and index large volumes of content, analytics, or sensor data. Backend reliability and debugging I help teams make systems easier to operate: logging, metrics, traces, CI/CD, Docker-based deployments, AWS infrastructure, database performance, worker reliability, and production debugging. Past work includes AI-powered SaaS reporting backends, a distributed news ingestion system, an internal domain-quality review tool, geospatial civic-tech platforms, cross-border payment integrations, and multi-node Elasticsearch infrastructure. I work best with clients who want clear technical judgment, honest scoping, async-friendly communication, and backend work that another engineer can maintain after delivery.
