At pulse by solutions, I developed a multilingual RAG chatbot for document Q&A and workflow automation, served through a Django REST API. I also architected a configurable LangGraph enterprise assistant for database queries, chart generation, and Gmail and Calendar integration.

I deployed Qwen3.6-35B-A3B on a four-GPU cluster for an on-premises production deployment, including its air-gapped Kubernetes environment. I also co-developed ModernAraBERT, adapting ModernBERT for Arabic; the research was accepted at LREC 2026.

At 21Tech, I built AI extensions for the HxGN EAM platform with a Django and LangChain backend. Earlier, I built a RAG system for technical PDFs and an EEG acquisition and preprocessing pipeline for a BCI-driven assistive robotics framework.
