## About

```text
At Castor, I designed and implemented ePRO and EDC applications supporting clinical trials, and architected AI and computer vision pipelines for medical document processing. I also led technical planning and built a shared UI component library.

Before Castor, I developed data-intensive web applications for UBS and investment banking, and earlier built software for banking, credit risk, insurance, and real estate. My work has included leading frontend teams, improving application performance, and developing automated test suites for access control devices.
