I am Karthik M, an AI Engineer with 2+ years building production-grade GenAI systems, currently at Soroco India. I architected Scout AI's 5-agent Text-to-SQL pipeline, serving 2M+ enterprise queries against a 60M+ row PostgreSQL warehouse with 99.5% uptime. My core expertise includes: * RAG & Retrieval Systems: Hybrid RAG (pgvector HNSW + tsvector/GIN), cross-encoder reranking, MMR diversification, multi-query RAG — achieving Table Recall@5 >94% and 96% RAGAS faithfulness * Agentic AI: Multi-agent orchestration, reflection loops, intent classification, ReAct agents * LLM Engineering: GPT-4o, prompt engineering, structured outputs, semantic caching, anti-hallucination frameworks I have worked on high-impact AI projects with enterprise clients including Amazon and Honeywell, taking systems from prototype to production scale. I'm passionate about building AI systems that are not just impressive demos, but reliable, precise, and deployable at production standards — and about mentoring others navigating the same transition into AI engineering.
