- 2026When the labels lie: auditing an LLM evaluation pipelineA golden-set + LLM-as-judge harness for a production ranking system surfaced a 43-point accuracy gap between models — and machine-generated ground-truth labels that were quietly wrong.
- 2026Hybrid retrieval with Reciprocal Rank Fusion for long-tail queriesFusing BM25 with dense embeddings recovered the niche recruiter queries that either method alone kept missing.
- 2026Prompts as production code: auditing 49 templates across 78 endpointsWhat a full audit of a prompt orchestration layer turned up, and the regression and observability scaffolding that came out of it.
- 2024Root-cause analysis over machine logs with hybrid-retrieval RAGHackathon · 1st runner-upA routed, multi-agent RAG system for enterprise logs: 89% relevance on technical queries over 500GB+ a day. The prototype placed 1st runner-up at LTIMindtree Hack The Future 2.0.
- 2024Fine-tuning Llama-3 and Mistral to curb domain hallucinations↗A fine-tuning pipeline for enterprise workloads: 65% fewer hallucinations and a 78% gain in domain accuracy.
- 2023AI-validated reconciliation for large-scale database migration↗Canvas Eureka: Spark + AI-based validation across 50+ enterprise migrations and 10TB+ of data, with 85% fewer errors. Part of the work behind LTIMindtree's official Databricks partnership.
