Saurabh Harak
Enterprise GenAI & AI Platform Engineering
Building production-grade RAG platforms, AI evaluation systems, and agentic workflows for enterprise use cases.
About
Senior GenAI Engineer building production AI systems
Currently a core engineer at TechnoMile, where I built Mila Chat — a multi-tenant enterprise RAG platform serving federal clients — and sole-architected the Unified AI Evaluation Platform that consolidated 3 codebases into one YAML-configurable system, cutting onboarding from 3 weeks to under 4 hours.
Previously fine-tuned Llama2/3 with LoRA/PEFT at Computech Corporation, built spatio-temporal data pipelines at ISB Hyderabad, and led drone autonomy R&D at Jatayu. MSc in Machine Learning & AI from Liverpool John Moores University.
Featured Projects
Enterprise-scale AI systems in production
Mila Chat
Multi-Tenant Enterprise RAG Platform
Core AI engineer on a production multi-tenant GenAI platform supporting federal enterprise clients across document intelligence and conversational AI. Designed retrieval and ingestion architecture with strict multi-tenant isolation at every layer — database, vector search, and conversation context.
Unified AI Evaluation Platform
LLM-as-Judge Evaluation System
Designed and built a centralized evaluation platform that consolidated 3 separate systems into one YAML-configurable framework. LLM-as-Judge engine with GPT-4.1 across 5 LLM metrics + 3 deterministic metrics, fully integrated into CI/CD with regression gating.
Creator GraphRAG
Multilingual Knowledge + Vector Retrieval System
Built a multilingual knowledge system that ingests books across Marathi, Hindi, and English, extracts structured concepts into Neo4j, and combines graph traversal with Qdrant vector similarity search for citation-aware content generation.
