Work Experience

AI Engineer

Hub Platform

Nov 2025 - Present

Engineered a Python-based AI SDLC orchestration platform using LangGraph, LiteLLM, MCP, SQLAlchemy, and PostgreSQL, automating 57 workflows across requirements, architecture, development, testing, and release. Built a cross-platform workflow engine supporting 5+ AI development environments and 30 role-specific AI skills, with dependency validation, human approval gates, multi-model routing, and requirements-to-test traceability. Implemented step-level context compression that reduced workflow prompt size by approximately 95%, from 74,862 to 3,544 characters, improving LLM token efficiency, execution cost, and scalability.

Internal BA

Cloumn Mapper

Feb 2025 - Jun 2025

Built an AI-driven Column mapping platform to align columns from 100+ heterogeneous files across multiple financial data sources into organization-defined schemas. Developed a hybrid schema-matching engine using LLMs, semantic retrieval, embeddings, and rule-based validation, achieving 85–92% automated column mapping accuracy while reducing manual mapping effort by 70%.

AI Engineer

JIO

Optimized LLM inference using Continuous Batching, DAF, and Prefix Caching, reducing context consumption by 38%. Created multimodal healthcare assistant using fintuned LLaMA 3.1, OCR, vision model and NER pipelines to process text + medical images, supporting 10K+ clinical queries with 2-5s response latency. Designed a hybrid retrieval system (BM25 + Vector Search) using Elasticsearch + Qdrant, improving response precision by 22%. Applied RAGAS evaluation (Faithfulness: 0.82, Relevance: 0.87) with doctor-in-the-loop validation and safe escalation handling. Orchestrated a temporal forecasting pipeline by separating static and dynamic features, improving wildfire forecast accuracy by 12%. Accelerated model experimentation using distributed training (PyTorch DDP), reducing training time by 45%. Developed a personalized coupon recommendation and ranking system using ALS collaborative filtering and LightGBM, leveraging user, product, and behavioral features to improve Click Through Rate from 2% to 4%. Deployed a complete pipeline with MLflow, Docker, and Airflow for automatic training and tracking of models. Engineered a distributed visual-search system leveraging FAISS indexing search, scaling to 1M+ img maintaining 2–7s retrieval latency. Deployed a scalable FastAPI microservice with autoscaling (Kubernetes), maintaining 99.2% uptime under peak load.

Data Science Intern

Boeing

Jun 2022 - Aug 2022

Constructed a FastAPI real-time analytics pipeline processing 5M+ flight records/month, cutting anomalies/errors by 90%. Optimized PostgreSQL queries with Redis caching, increasing throughput by 70% and cutting latency from 500ms → 90ms.
