What I'm looking for

I seek a senior technical role building production LLM/RAG systems with strong MLOps, collaboration with cross-functional teams, and opportunities to mentor engineers.

I am a Senior AI/ML engineer with ten years delivering production-grade AI systems, specialising in LLMs, RAG, multi-agent systems, NLP, and model fine-tuning. I lead architecture and implementation of end-to-end AI platforms that prioritize reliability, cost and performance optimization, and compliance in regulated domains.

I have built scalable ingestion, evaluation, and LLMOps/MLOps pipelines, integrated multimodal interfaces, and applied RLHF and instruction tuning to improve model alignment. I mentor engineers, influence cross-functional stakeholders, and translate complex AI capabilities into durable, high-impact business solutions across healthcare, finance, and e-commerce.
