Hi, I'm Anurag Singh
AI & Data Engineer
Building end-to-end data pipelines (batch, near-real-time, real-time) and production Generative AI / Agentic systems. Sole developer of 5 production enterprise platforms serving 100+ users and 200K+ monthly transactions across Finance, Operations, and Sales — pairing Spark/Kafka lakehouse engineering with RAG, multi-agent MCP workflows, and full-stack delivery.
Architecting On-Premise AI & Data Engines
"Building production systems that ship and scale, not just prototypes that impress."
I am an AI & Data Engineer with 2+ years of experience single-handedly building and deploying production-ready machine learning systems, advanced RAG architectures, local-LLM agents, and high-performance data pipelines.
At TRPW Strategic Partners, I built 5 internal enterprise platforms — Limestone (reconciliation), BetelTMS (task management), BetelVMS (vendor billing), Excellia AI (spreadsheet intelligence), and SOP Intelligence Portal (RAG chatbot) — operating 100% on-premise with zero data leaving client infrastructure.
RAG & Agentic AI
6-stage hybrid retrieval funnels (BM25 + vector search + RRF + cross-encoder reranking + MMR + grounded refusal) and 19-tool MCP servers running local LLMs (Ollama).
Data & Lakehouse Pipelines
Spark, Kafka, Snowflake, and Iceberg architectures for batch and near-real-time streaming, automated anomaly detection (Isolation Forest), and high-volume ETL.
Full-Stack Delivery
Production FastAPI / Flask REST backends, React 19, Vite, TanStack Query, Tailwind CSS, PostgreSQL/pgvector, Redis, and containerized Docker deployments.
Professional Journey
AI & Data Engineer (Data Analyst)
Mar 2024 – PresentTRPW Strategic Partners • Gurugram, India
- Sole developer of 5 production enterprise platforms — Limestone (reconciliation), BetelTMS (task management), BetelVMS (vendor billing), Excellia AI (spreadsheet intelligence), and SOP Intelligence Portal (RAG chatbot) — serving 100+ users and 200K+ monthly transactions.
- Deployed local LLMs, RAG pipelines, ML anomaly detection, and OCR across all platforms — 100% on-premise, zero data leaving client infrastructure.
- Designed shared security architecture: multi-tenant RBAC, OTP authentication, session management, and multi-layer prompt-injection filtering.
- Paytm KYC Engagement: Built OCR pipeline (Google Cloud Vision + Tesseract) with SequenceMatcher/ML name matching and bulk deduplication across large Excel datasets — 90% less manual audit effort.
- Automated reconciliation of 10,000+ monthly transactions, eliminating 32+ hours of weekly manual finance work (80% faster).
- OYO / PRISM Fraud Audit: Automated Excel audit pipeline (Python, Pandas, NumPy, SQL, Regex) with anomaly checks — 60% faster analyst cycle time.
