From IoT Circuits to AI Systems

I build things that turn messy data into clear decisions. Whether it's automating enrollment pipelines, deploying multi-agent healthcare systems, or wiring up IoT sensors for urban safety, I care about the full loop: real data, real stakeholders, real impact.

The Journey

Every role taught me something different. Here's the path so far.

2024 to Present AI + Analytics

Business & Data Analyst, UMass Lowell

Where I learned to build for stakeholders, not just for code

  • Reduced admissions data discrepancies by 32% across Salesforce, CAS, PeopleSoft & OAC.
  • Implemented a RAG framework integrating enrollment datasets, improving AI-driven forecasting by 40%.
  • Automated analytics workflows with Python & SQL, reclaiming roughly 15 hours per week.
  • Converted 10,000+ survey responses into actionable insights using NLP sentiment analysis (VADER).
  • Built the ABTS population monitoring dashboard in OAC for real-time tracking of 1,000+ eligible students.
2022 to 2023 Enterprise Data

Data Analyst, Société Générale, Bengaluru

Where I learned what "production-grade" actually means

  • Maintained 99.99% data integrity across 50+ SQL Server environments.
  • Built SSIS validation and transformation logic, reducing reporting discrepancies by 25%.
  • Co-built a .NET API for real-time BI dashboard access, saving 50 hours per week of manual extraction.
  • Coordinated with Paris-based engineering teams to align API architecture with enterprise standards.
2018 to 2022 · The Hardware Years

Smart Coffee Dispenser

RFID-authenticated coffee machine built with Raspberry Pi Pico. Users scan their card to pick from 4 coffee types. The system reads the card via SPI-based RC522, authenticates, and controls relay-driven dispensing. All MicroPython.

Smart Waste & Manhole Monitoring

IoT system tackling two urban safety problems in Indian cities. Ultrasonic sensors track waste bin fill levels in real time, while gas sensors (methane, H₂S), water level detectors, and tilt sensors monitor manhole status. Open and toxic manholes cause hundreds of sanitary worker deaths every year. Automated GSM/Wi-Fi alerts reach municipal authorities before workers approach hazardous sites.

Geopolitical Risk & Portfolio Dashboard

Live news feeds + 10 years of market data to assess portfolio downside under real-world crisis scenarios. Regime-switching tail risk framework using VaR, CVaR, tail dependence & Clayton copula modeling. Separate crash models for calm vs. crisis markets.

Copula Models GARCH NewsAPI Streamlit

FDA Medical Device Recall Intelligence

End-to-end pipeline processing 10M+ FDA recall records across 9,100+ devices. Custom Recall Pattern Severity Score (RPSS) across 5 risk dimensions. ML-based recall prediction + time series forecasting. Top 2% critical devices drive 60%+ of high severity recalls.

Python SQL Server scikit-learn Streamlit

Tesla Model S Battery Overheating: Six Sigma

Academic Lean Six Sigma project applying the full DMAIC framework to a real-world problem: Tesla Model S batteries overheating during supercharging in extreme heat. Ran a 5-factor DOE analysis (ambient temperature, charging algorithm, cooling system, battery life cycle, safety procedures), identified root causes using fishbone and Pareto analysis, and proposed actionable improvements including supercharging restrictions for older batteries, alternative coolant fluids, and revised safety testing. Targeted a 40% reduction in overheating incidents.
