Data Scientist
Neosoft Technologies Pvt Ltd | Mumbai
10.2023 - Current
  • Deliver end-to-end GenAI and ML solutions for client engagements across insurance, HR, pre-sales, and industrial process optimization, from requirement analysis to production deployment.
  • Build agentic and RAG-based systems with LangChain and LangGraph, integrating GPT and LLaMA models with vector databases (Qdrant, Chroma).
  • Own the full ML lifecycle: data ingestion, preprocessing, model training, evaluation, deployment, monitoring, and retraining.
  • Develop real-time computer vision solutions with OpenCV and YOLO, and serve models in production through scalable FastAPI and Flask REST APIs.
  • Key projects: AI Insurance Chatbot (RAG + MCP + AI Gateway), RFP Estimator Agent (estimation time cut from 2 days to ~10 minutes), LangGraph Resume Parser, and industrial ML for furnace optimization.

Education

Bachelor of Engineering - Information Technology

VPP College of Engineering | Mumbai | 01.2023

CGPA: 9.00/10

HSC 12th - Science

S.S. Jr. College Seawoods | Navi Mumbai | 01.2019
  • Percentage: 64.77%

Projects

  • AI Insurance Chatbot | LangChain, RAG, MCP, AWS
  • Built a production insurance chatbot with an AI Gateway handling LLM routing, auth, rate limiting and observability.
  • Automated PDF ingestion from AWS S3 with hash-based change detection, section chunking, embeddings and ChromaDB.
  • LLM intent classifier routes each query to RAG, MCP tools or both; hybrid retrieval with cross-encoder re-ranking on GPT-4o mini.
  • Enforced LLM guardrails and raised answer accuracy through prompt engineering, retrieval tuning and precision/recall evaluation.
  • RFP Estimator Agent | LangChain Multi-Agent, Flask
  • Cut RFP estimation time from 2 days to ~10 minutes for 30-50 page proposals.
  • Multi-agent system covering requirement analysis, effort estimation, validation and response generation, with deadline-aware scheduling.
  • Natural-language editing of estimates with version history and snapshot restore.
  • Resume Parser for HR | LangGraph, PyMuPDF
  • 4-node stateful LangGraph pipeline with conditional edge routing.
  • Layout-aware parsing of multi-column resumes; LLM evaluation returns validated JSON with match scores, skill gaps and role alignment.
  • Industrial ML - Ingenero Digitization | Scikit-learn, Autoencoders
  • Predictive models (Linear Regression, SVM, Random Forest) and autoencoder anomaly detection on 100+ plant features.
  • Live Benchmarking and CoilSim simulation models; furnace efficiency ranking optimized via feed rates and coil outlet temperature.

Certification

  • Data Science with Python - Simplilearn (2023)
  • Python - IBM Global Certification (2022)

Accomplishments

  • Published Patent: AI-based Pothole Detection and Filling System Using Recycled Plastic Waste for Sustainable Infrastructure.
  • Research Paper (IJIRT, 2026): Disk-Streamed Layerwise Inference of Frontier Language Models on Memory-Constrained Hardware.
  • Research Paper (IJIRT, 2026): Composite Guard - A Graph-Structural, Longitudinally-Monitored Detector for Emergent Guardrail-Bypass in Multi-Agent Systems.
  • Business Impact: Built an RFP Estimator Agent that cut proposal estimation time from 2 days to ~10 minutes.
