About

My Introduction

Senior AI/ML Engineer specializing in production-grade AI systems, multi-agent architectures, Retrieval-Augmented Generation (RAG), and LLM optimization. I've designed and deployed end-to-end AI systems that automate complex workflows, reduce manual analysis by up to 85%, and cut LLM inference costs by as much as 60% through intelligent orchestration, retrieval, and optimization. My open-source fine-tuned language model has surpassed 12,000 downloads on Hugging Face while achieving 97.8% task accuracy, reflecting my focus on building efficient models that solve real-world problems. From distributed multi-agent pipelines and scalable FastAPI backends to production RAG systems and LLM evaluation workflows, I build AI products that move beyond demos into reliable, maintainable systems used by real teams. If you're building serious AI infrastructure - I'd love to connect.
