I build the software that runs medical practices — the EMR, billing systems, and the AI that handles clinical notes. 7 years in, previously at Amazon and Wells Fargo.

Background
How I got here.
I've been writing software for about 7 years now. Started at Amazon in Hyderabad working on e-commerce backend systems, moved to the US for grad school at Illinois Tech, then did a stretch at Wells Fargo before landing in healthcare — which honestly wasn't the plan, but turned out to be the most interesting work I've done.
Right now I'm building the software stack at Pain Treatment Centers of America — the EMR that clinical staff use every day, an AI Scribe that handles documentation so doctors can focus on the patient, a cost estimator so patients know what they owe before walking in, and the revenue system that makes sure the clinic actually gets paid. It's a small team, so I own a lot of it end to end.

Featured Work
Systems that medical practices rely on every day.
Three production platforms built across the clinical, financial, and patient-facing layers of healthcare.
Clinical Data Management Platform
A full-stack EMR platform that unifies patient records, appointments, and clinical data into a single role-based dashboard used by clinical staff across multiple pain treatment locations.
What wasn't working
Clinical staff across multiple locations had no unified system for accessing patient records and appointment history, resulting in fragmented workflows and slow chart reviews during patient encounters.
What I built
Designed and built a full-stack EMR dashboard with real-time data access, role-based access control, and HL7 messaging integration — consolidating all patient data into a single, fast-loading interface.
Patient Cost Estimation Engine
A real-time cost estimation engine that processes insurance eligibility and benefit data to provide patients with accurate out-of-pocket cost estimates before services are delivered.
What wasn't working
Patients received care without knowing their financial responsibility, leading to billing surprises, delayed payments, and erosion of trust between the practice and its patients.
What I built
Built a real-time estimation engine integrating with insurance eligibility APIs to calculate patient deductibles, copays, and coinsurance — surfacing accurate cost estimates prior to every appointment.
Revenue Cycle & Cash Flow Platform
An end-to-end RCM platform covering the complete claims lifecycle — from submission through ERA/835 processing, denial management, and real-time cash flow reporting for practice administrators.
What wasn't working
Multi-provider practices lacked visibility into the complete claims lifecycle, causing missed revenue, uncaught denials, and cash flow forecasting that was weeks behind reality.
What I built
Developed a comprehensive RCM platform that automates claim submission, parses ERA/835 remittance files, surfaces denial patterns, and delivers a real-time cash flow dashboard for administrators.
