Work Experience

Data Scientist (Consultant)
Deloitte USI
Jan 2025 - Present · Bengaluru, India
OmniScout Multi-Tenant AI Platform
- Architected "OmniScout," a scalable multi-tenant platform consolidating 5+ domain apps into a unified FastAPI system; recognized by leadership for delivering a projected $50M annual benefit and increasing experimental success rates by 30% for 500+ researchers
- Engineered a production-grade Multi-Agent RAG system using LangGraph and AWS Neptune to orchestrate 5+ specialized agents (Query Analyzer, Tool Orchestrator); implemented streaming responses via SSE with automated inline citations and fact-checking
- Developed a Deep Research Agent and SWOT Analysis workflow for pharmaceutical intelligence, utilizing parallel execution to slash research cycles from hours to minutes while maintaining strict scientific accuracy
- Developed a custom MCP server using FastAPI-MCP to standardize and expose internal tools (such as HR, DR, and SWOT analytics) as reusable AI capabilities; streamlined tool discovery and cut cross-team deployment cycles by 40% through a unified Model Context Protocol integration
- Designed a YAML-driven prompt orchestration framework and a custom Shifted Context Window algorithm for query optimization; enabled independent tenant workflows and dynamic configuration loading while eliminating code redundancy across teams
- Developed an end-to-end document intelligence pipeline using Mistral OCR for structured PDF extraction and a custom hybrid search engine (BM25 + Neural Sparse encoding) on OpenSearch; eliminated ML-node dependency by running sparse inference externally, achieving high-precision retrieval across pharmaceutical research documents.
Eli Lilly Chat Agent
- Architected an advanced SQL Agent using LangChain and Anthropic Claude on AWS Bedrock, enabling natural language querying of AWS RDS; achieved 95% query accuracy, outperforming OpenAI benchmarks and securing client retention
- Engineered a dynamic few-shot learning system (OpenSearch) and Chain of Thought (CoT) prompting pipeline; optimized logic for complex joins and validation, boosting domain accuracy by 18% and reducing hallucinations by 31%
- Developed a Multi-Agent RAG ecosystem using CrewAI to orchestrate 4 specialized agents (Router, Retriever, Synthesizer, Evaluator) for processing complex clinical trial documents and scientific data
- Implemented a custom hybrid search engine combining FAISS vector similarity with BM25 keyword matching and DeepEval for automated quality metrics, ensuring high-precision retrieval for pharmaceutical research

Software Engineer
Cisco Systems India Pvt Ltd
Jan 2021 - Dec 2024 · Bengaluru, India
Testbed Reservation System
- Architected a high-availability Django platform scaled to serve 300+ engineers and 5,000+ monthly reservations, eliminating 100% of double-booking race conditions by implementing PostgreSQL row-level locking within atomic transactions
- Engineered a non-blocking Celery-Redis asynchronous notification system and built utilization dashboards, which together reduced testbed idle time by 45% (recovering $150K in annual value)
ML Testbed Predictor
- Engineered an ML predictive pipeline to optimize testbed allocation, benchmarking 7+ algorithms; achieved 0.91 AUC using Gradient Boosting, outperforming baseline models by 35% and reducing idle time allocation failures
- Implemented a robust preprocessing workflow using StandardScaler and LabelEncoder, serializing the pipeline with joblib to prevent training-serving skew; served real-time predictions via a Flask REST API
Cisco Wiki Analytics Dashboard
- Engineered a Flask and Pandas dashboard to automate executive reporting by ingesting, cleaning, and programmatically standardizing raw Excel data, which reduced manual report generation time by 40%
- Delivered hierarchical, interactive chart views tailored for leadership, enabling Directors to see high-level aggregates and Managers to drill-down into specific team/engineer performance for data-driven decision-making
Testbed Chatbot
- Built a RAG chatbot (FastAPI, OpenAI Embeddings, ChromaDB) that enabled natural language queries for hardware specs, reducing information lookup time by 75%
