My Career
Real Private Credit - UI/UX & Full-Stack Developer
Sep 2025 - Nov 2025
Real Private Credit was a fast-moving startup environment where I got to build things from scratch and ship quickly. My main project was NavLend, a lending platform that lets investment fund members originate loans and use their fund interest as collateral. I designed the interface and built both the React/TypeScript front end and the FastAPI/SQLAlchemy backend, working closely with a former Fortune 1000 architecture leader to deploy the platform on AWS. I also created a real-time conversational AI avatar that the team used as a top-of-funnel sales tool that helped secure more than 10 high-profile meetings. The whole experience was short but intense, and I walked away with a stronger sense of how to build polished software quickly in a high-pressure environment.
Client Work
CCS Cases
The CCS Cases application is a case simulator used to prepare medical school residents for the Step 3 portion of the USMLE exam. This exam is a final step in medical students securing their license to practice medicine independently. I was tasked with the UI/UX design and front-end development of this platform. The project is live and can be viewed by creating a demo account at the link below.
This platform has been used by over 100,000 future doctors all over the globe.
UltrasoundCards Website
This JAMSTACK website builder was designed and built around selling the UltrasoundCards application, later used again later to build the PsychQB marketing website. I was tasked with designing the UI/UX, writing the copy, and full-stack development of the resulting platform.
View ProjectUltrasound Cards
UltrasoundCards is a progressive web app created to help ultrasonography students study for the ARDMS exams, helping them to become licensed ultrasound technicians. I was tasked with the UI/UX design and front-end build out of this platform.
This application was later ported to include supplemental content for the CCS Cases application and used by thousands of users worldwide.
