Work experience · 02 roles

Real work, real impact.

Every role I've taken has been about building something that genuinely works for real people, not just demos.

Healthcare SaaS · IoT + machine learning · Cloud · Gen AI · NLP · OCR

01 / EmedLogix

Intelligent System Developer

Worked as an AI Product Developer Intern at EmedLogix (US based healthcare technology SaaS), contributing to a production provider onboarding and credential management system active in the market.

What I built

Gen AI inside a real credentialing platform

Healthcare credentialing is slow, manual and document heavy. I worked on bringing Gen AI into a production credentialing application end to end, handling sensitive, real US healthcare provider data under strict monitoring.

Text to SQL Agent
My core role. I developed an agent that converts plain English questions into SQL and retrieves the data. The agent knows the database schema of the PostgreSQL database on AWS RDS.
OCR Pipeline with Qwen2.5 VL 7B
Built an OCR pipeline on Qwen2.5 VL 7B for accurate text extraction across varied documents, autofilling form fields and saving a lot of time compared with traditional manual filling.
Document Deadline Tracking
Every provider carries 60+ documents. I added automated deadlines for each document of every provider to track its lifecycle and renewal cycle, with alerts 30 days before it falls due.
CAQH & NPI APIs
Worked with the real CAQH and NPI APIs from the US to retrieve and validate provider information.
Secure Sign in
Integrated Azure Entra ID SSO login through a web service and added Cloudflare bot verification for additional security.
Login & Landing Page Design
Worked on the frontend design of the login page and landing page to make them user friendly.
Beta Deployment on AWS
Deployed the beta version of the application to the company on AWS during the internship.

02 / Microsoft × Edunet

AI/ML Intern

A virtual internship with Microsoft and the Edunet Foundation: core machine learning on the Microsoft Learn portal, from the basics to intermediate algorithms and techniques, finished with a capstone project of my own.

What I built

AI Nose, the capstone

Microsoft Learn gave me quality courses on core machine learning, from the basics to intermediate, and introduced me to a range of ML algorithms and techniques. One algorithm caught my interest: the Random Forest classifier. With my background in IoT and hardware, the idea for the capstone followed: an AI nose that can actually smell its environment, detect particular gases, classify them in real time and alert when a gas exceeds a safety threshold.

IoT Hardware & Sensors
Programmed an ESP32 microcontroller integrated with MQ3 and MQ9 gas sensors. These sensors measure concentrations of alcohol vapors, carbon monoxide, methane, LPG, and hydrogen.
Signal Processing & Cloud Sync
Developed initial ESP32 preprocessing routines for sensor calibration, value normalization, and noise filtering. Timestamped datasets were streamed in real time to Firebase Realtime Database for instant synchronization.
Odor Level Classification Model
Collected a labeled sensor dataset categorized into Clean, Moderate, Foul, and Very Foul. Tested various machine learning models to choose the most reliable and fastest one, settling on a decision tree based algorithm (Random Forest) that achieves 98% accuracy and runs in milliseconds on the server.
Live Monitoring Web Dashboard
Built a Gradio web application visualizing live sensor readings, predicted odor classes, and historical trends for remote monitoring.
Automated Sanitation Alerts
Programmed alerts that trigger whenever predicted levels are Foul or Very Foul, notifying maintenance teams immediately so they can clean proactively rather than on a fixed schedule.

Key highlights

Hardware: ESP32 Microcontroller
Sensors: MQ3 & MQ9 Gas Sensors
Database: Firebase Realtime Database
Dashboard: Python Gradio Visualizer

Top 1,000 at the Amazon ML Challenge 2026

Match noisy business records from three sources with no shared ID, across millions of rows in 23+ Indic languages. We built a transliteration engine on AI4Bharat's model, ran experiments in parallel on 4 PCs and every GPU we had, and combined our models into a stacked ensemble. We held a top 350 to 500 rank on the live public leaderboard throughout the challenge and beat 94.1% of submissions, finishing just 0.0053 from the top score, on a test set that quietly added France, a country we had never trained on.
