I'm Vatsa Joshi — an AI/ML engineer in Bengaluru focused on LLM evaluation, fine-tuning and agentic systems. 2+ years shipping production LLM systems, including a founding AI engineer role owning retrieval and memory infrastructure end-to-end.
I've built and owned evaluation harnesses for production LLM pipelines — including a legal NER system validated to 96% document-level zero-failure across a 4M-row eval set while cutting extraction cost 25x over an 8M-judgment corpus. Hands-on with LoRA/QLoRA, DeepSpeed ZeRO, red-teaming, and adversarial/deepfake detection (IEEE-published). High-ownership; ships to production.
