Jan 2020 – Present | Chicago, Illinois, United States I build and scale enterprise platforms that sit at the intersection of healthcare and technology driving efficiency, automation, and revenue growth at scale. At Tempus, I engineered the core ordering platform powering intake from 1,000+ institutions and research partners, with lifecycle management tools that handle complex clinical workflows end-to-end. On the business side, I delivered platforms that manage $450M in annual billing orchestration and spearheaded new test integrations that generated an additional $50M in yearly revenue. I also designed provider-facing models such as subscription frameworks for early cancer detection and automated CDx-to-lab test conversions that expanded Medicare/Medicaid eligibility and cut 30 minutes of manual work per test, multiplying impact across thousands of orders. My technical expertise spans full-stack development and cloud infrastructure: JavaScript, TypeScript, React, MobX, Node.js, NestJS, Postgres, Docker, Redis, Terraform, GCP, and modern monitoring/testing stacks (Grafana, Splunk, Jest, Puppeteer, Playwright).

The platform was powered by a custom geospatial library with advanced mapping features including geofencing, asset clustering, overlays, and route tracing built for extensibility and performance. I also engineered a rules-based monitoring engine that ingests sensor data streams, detects anomalies, and generates actionable events, enabling proactive asset management and long-term trend analysis. To support configurability and enterprise adoption, I built a JSON-driven UI framework that allowed teams to rapidly deploy tailored workflows across multiple verticals, reducing time-to-market for new solutions. I also delivered a reusable charting library (AngularJS + D3.js) for consistent visualization across applications, and established automated testing frameworks that ensured reliability across large-scale deployments.
