Senior Data Scientist
Mondee Pvt. Ltd.
Hyderabad, India
- ▸Architected a medical-grade GraphRAG audio chatbot for our flagship clinical decision support system CDSS deployed across Surekha Hospital Chain and BhaktiVedant Hospital, by constructing structured knowledge graphs from medical textbooks using NER and Neo4J, enabling doctors to query alternative possible diagnosis and treatment protocols with traceable, hallucination-resistant responses via a LangChain-powered retrieval layer.
- ▸Engineered a drug–drug interaction checker and dosage scheduler agent served through a Model Context Protocol (MCP) interface, integrating real-time data from RxNorm and PubMed APIs to surface conflict alerts and patient-specific dosage recommendations within the chat session.
- ▸Led end-to-end fine-tuning and serving of Medgemma-27b-text-it for domain-specific clinical NLP tasks using Unsloth and vLLM, coordinating data curation, training, and evaluation pipelines with research scholars from IIT Madras and IIT Hyderabad.
- ▸Directed large-scale Speech-to-Text (STT/ASR) data preparation and multimodal fine-tuning of gemma-3n-e2b-it via LoRA and TGI-based serving, overseeing live clinical audio collection, Subject Matter Expert annotation, and quality control to build a medical voice agent capable of real-time clinical transcription and Doctor's Note generation.
Senior Member Technical (AI/ML)
ADP India Pvt. Ltd.
Hyderabad, India
- ▸Designed and deployed a Knowledge-Graph based RAG pipeline on AWS Neptune & Bedrock orchestrated via LangGraph, enhancing financial data processing accuracy and minimising AI hallucinations — recognised as runner-up in the ADP Global Hackathon (2024).
- ▸Developed an intelligent Process Mining Chatbot for Global Payroll Services using Microsoft Power Automate and Databricks to analyse transaction patterns across millions of client records, optimising payment workflows across 73 payroll cycles per client on average.
- ▸Engineered an agentic assistant built on Google Agent Development Kit and AWS Opensearch that drafts context-aware emails and schedules meetings in real-time by checking live calendars, saving equivalent to 24 hours per user per month — currently rolled out across all ADP employees.
- ▸Built a scalable QR code detection, decoding, and masking pipeline with a fine-tuned YOLOv8 for multi-orientation detection and OpenCV for automated region masking, sanitising financial documents prior to downstream processing at scale across millions of payroll documents.
- ▸Developed an Indic PII detection and redaction system for financial regulatory compliance using fine-tuned NER models via HuggingFace Transformers and SpaCy with IndicNLP, identifying sensitive entities — Aadhaar, PAN, account numbers, names across 10+ Indic scripts — from payroll and HR documents.
Junior Data Scientist
Claim Genius Pvt. Ltd.
Remote, India
- ▸Built a high-performance Instance Segmentation pipeline using Detectron2 served via FastAPI for vehicle parts identification, improving segmentation accuracy to 95% mAP and accelerating assessment throughput by 26%; integrated GradCAM++ visualisations for regulatory model interpretability.
- ▸Engineered an automated ML pipeline failure tracing system using MLflow to monitor inference-time distributions and surface root-cause analysis on mispredictions, reducing manual diagnosis time by 30%.
- ▸Deployed an image super-resolution and denoising ensemble combining SWIN2SR Transformer and NAFNet pre-trained models to upscale and denoise compressed input images, reducing model failures by 16% and improving downstream prediction accuracy by 12%.
- ▸Built an automatic labelling error-detection service using Scikit-learn confidence scoring that flagged curation errors — saving 6 man-hours per head per sprint — and trained PyTorch GAN models for synthetic image generation to resolve class imbalance in rare damage categories.
- ▸Designed a geometric flat-tyre detection approach via OpenCV polygon analysis enabling reliable detection with zero curated data, and boosted vehicle damage severity classification by 3% per class through a fusion ensemble combining PyTorch CNN features with XGBoost structured metadata.
