Ahmed B.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

I build production-grade RAG systems, autonomous AI agents, and secure automation pipelines that turn complex data into intelligent, queryable enterprise applications. Currently pursuing a PhD in AI for Cybersecurity at UM6P, where I apply Graph Neural Networks and NLP transformers to detect Advanced Persistent Threats (APTs). Before that, I spent 6+ years shipping real software across blockchain (PayRue, London), backend APIs (Paris), and AI engineering roles. ━━ WHAT I BUILD FOR YOU ━━ ▸ Enterprise RAG Pipelines — Custom retrieval-augmented generation with LangChain, vector databases, and private, secure deployment of open-source LLMs (DeepSeek, Llama, Qwen). ▸ AI Agents & Production Automation — Complex, multi-step reasoning agents and fully self-hosted workflow automation engines using n8n and Docker. ▸ High-Performance ML Deployment — Scalable backend APIs with FastAPI, containerized deployments, and hardware optimization leveraging CUDA, OpenMP, MPI, and SLURM for HPC environments. ▸ Cybersecurity AI & Auditing — Anomaly detection, fuzzing infrastructure, vulnerability classification, and network intrusion detection systems. ▸ Full-Stack & Database Architecture — End-to-end development integrating robust backends with modern frontend applications and scalable data stores like MongoDB Atlas and Firebase. ━━ TECH STACK ━━ Python · PyTorch · LangChain · HuggingFace · DGL/PyG · CUDA · Docker · FastAPI · Linux ━━ WHY WORK WITH ME ━━ ✔ PhD researcher — I understand the theory behind what I build, not just the APIs ✔ I've built a Personal Digital Twin (bargady.online) powered by a custom RAG pipeline over my own knowledge base — this is production code, not a tutorial project ✔ Clear communication, daily updates, and I flag blockers before they become problems ✔ English C1 — no miscommunication on scope or requirements If you need someone who can read a paper on Monday and have a working prototype by Friday, let's talk.
