What I'm looking for

I’m looking for a team where I can ship impactful frontend and mobile features, collaborate closely with product and engineering, and keep improving through fast feedback—while still applying my data and research skills to build smarter experiences.

I’m a frontend/fullstack developer focused on building user-facing, cross-platform experiences with React Native and Expo. In my current role, I led frontend development of a cross-platform mobile application, engineering responsive UI components to visualize real-time climbing progress and participant milestones.

I also bring strong collaboration habits to every build. I’ve worked with cross-functional teams via GitHub to ensure smooth integration between frontend and backend systems, and I’ve gathered requirements directly from a real-world client to iterate on product features.

Beyond product development, I contribute to medical imaging research as a Software Research Assistant—performing manual SAC segmentation on CT calcium score images with 3D Slicer and preparing/annotating patient imaging datasets for cardiovascular event prediction. I’m excited to keep combining clean frontend engineering with thoughtful data work, especially where iteration, quality, and real user impact matter.
