You will get a FastAPI backend built for your AI application
Rising Talent
Project details
A clean, documented, deployable backend to serve your AI/ML models and power your app. I build cloud-native FastAPI services — I run infrastructure serving ~800 users at 99.7% uptime. You get well-structured REST endpoints, auth, validation, auto-generated API docs, Docker packaging, and a clear path to deployment. Tell me what your API needs to do and what it connects to. I'll scope it cleanly and deliver code your team can run and extend. Stack: FastAPI, Python, PostgreSQL, Docker, CI/CD.

About Marwan
AI Engineer | LLM/RAG, AI Chatbots & Computer Vision (Python)
Jeddah, Saudi Arabia - 6:38 am local time
Over the last 3+ years I've delivered AI to real users as an engineer and startup CTO: a camera-based vital-sign (rPPG) engine running at 91% heart-rate accuracy on live video, an industrial computer-vision safety platform processing 6 video streams in real time, and production RAG pipelines answering queries in under 165 ms over 30,000+ documents. I'm also the author of 5 peer-reviewed IEEE papers and a national finalist in Saudi Arabia's Future Minerals Pioneers competition.
WHAT I CAN BUILD FOR YOU
• RAG chatbots & AI assistants over your own documents, data, or website (LangChain, FAISS/ChromaDB, OpenAI/Claude/Llama).
• LLM integrations & AI features inside your product — chat, summarization, extraction, agents, structured outputs.
• Computer vision systems — object/PPE/defect detection, tracking, real-time video analytics (YOLO v8/v11, OpenCV, RTSP, edge inference).
• AI/ML model development — training, fine-tuning, evaluation, and getting models from prototype to production.
• AI backends & APIs — FastAPI microservices, Docker, clean REST APIs, dashboards (React/TypeScript).
PROOF (real, measurable)
• rPPG vital-sign engine: 91% HR accuracy (±2.5 BPM MAE) at 28 FPS, deployed to a mobile SDK for 300+ users.
• AURA CV safety platform: 94.2% mAP PPE detection on 11,000 images; cut manual audit overhead 73%.
• Enterprise RAG pipeline: 76% precision@5, sub-165 ms latency, fully containerized.
• As CTO: shipped infra serving ~800 users at 99.7% uptime and cut new-AI-feature validation to 24–72 hours.
HOW I WORK
Clear communication, fast iteration, and honest scoping. I confirm the goal, ship a working slice quickly, and keep you updated. I write maintainable code with tests and document what I deliver so your team can run it.
I'm fluent in English and a native Arabic speaker — so I'm a strong fit for MENA/Gulf clients and for Arabic-language AI (Arabic RAG, NLP, and chatbots). Trained through SDAIA and KAUST. Available now for both one-off projects and ongoing work.
If you have an AI idea — a chatbot, an automation, a vision system, or a model — message me with what you're trying to achieve and I'll tell you exactly how I'd build it.

Build & deploy your FastAPI backend
I design well-structured REST endpoints with validation, auth, and auto-generated docs, package it with Docker, and hand off deployable code.
