GenAI Principal Engineer / Solution Architect at Turing
September 1, 2022 - Present
Built a multi-layered investigative agentic platform on a proprietary graph of 10B+ entities/relationships to support government investigations into smuggling, money laundering, and forced labour. Architected a multi-stage Golden Dataset pipeline using Claude Skills to synthesize high-quality golden rows and enforced curation via TL;DR-style constraints, quality gates, and rubric-based metrics. Integrated an Analyst agent using MCP with a customer graph DB and built regression testing on real customer queries plus the golden dataset to validate tradecraft. Developed an Evaluation agent and LLM regression evaluation framework inspired by ELM, including inline critique for structured feedback loops. Fine-tuned multiple LLMs (e.g., OLMo, Qwen, Phi) using LoRA on curated training/evaluation splits, leveraging parallel A100 40GB GPUs. Also created an enterprise Agent Fabric platform with persona/prompt versioning, KB management, sub-agent integration via MCP/REST, DAG workflows, guardrails/
