About

Professional summary

I am a Senior Generative AI and Backend Engineer focused on designing and delivering production-grade RAG and LLM systems. My work spans document ingestion, hybrid retrieval, reranking, context-aware generation, model evaluation, API delivery, and deployment.

I have led end-to-end AI product development teams and made technical architecture decisions for complex production software. I combine applied machine learning expertise with strong backend engineering practices to create reliable, maintainable AI platforms.

I have hands-on experience fine-tuning and evaluating models through structured MLflow experiments, improving retrieval quality and answer accuracy while making model changes measurable and repeatable. I also build and operate on-premise LLM serving solutions using vLLM.

My background includes deep learning, computer vision, C++, Python, and Autodesk API integrations. I have delivered engineering automation and AI-powered inspection systems that substantially reduced manual work and turnaround times.

I am experienced in inference optimization and production deployment, including moving deep-learning segmentation workloads from Python to C++ for low-latency GPU inference. I enjoy solving performance-critical engineering problems and turning AI research into useful production systems.

I have worked across oil and gas, structural design, engineering automation, and inspection domains. I bring a practical product mindset to AI development, with emphasis on technical quality, measurable outcomes, and cross-disciplinary collaboration.

Career history

RAG & Machine Learning Product Development Team Lead Amn Mouj

Led end-to-end development of production RAG and LLM systems, including document ingestion, hybrid retrieval, reranking, generation, evaluation, API delivery, and deployment.

Fine-tuned and evaluated models with MLflow through structured experiments that improved retrieval quality and answer accuracy. Designed and deployed on-premise LLM serving with vLLM and led delivery of an industry RAG platform for oil and gas clients.

AI and Software Team Lead Structure Plus Group

Led applied machine learning and C++ engineering for structural-design products, making technical and architectural decisions across complex production software initiatives.

Built engineering automation and Autodesk platform API integrations, leading cross-disciplinary tooling that reduced building weight by 50%. Progressed from Software Application Developer to team lead and owned technical direction, maintainability, collaboration, and production delivery.

AI Solutions Developer Water Active.Co

Built and deployed deep-learning computer-vision models within a production application.

Reduced inspection-report turnaround time from more than one month to several hours through model development, application integration, and production deployment.

C++ for High-Speed Deep Learning Amn Mouj (Fastory)

Optimized production deep-learning inference by migrating segmentation workloads from Python to C++.

Achieved approximately 10 ms per frame on an RTX 4070 and as low as 7 ms with batch processing.

Software Developer Bonyano Group

Built C++ and C# AutoCAD automation tools using Autodesk APIs for engineering drawing and detailing workflows.

Improved workflow accuracy and reduced repetitive manual work through engineering automation.
