PROFILE

Katrin Khilko

Worked across the formio/core, formio/formio, and formio/formio.js repositories to enhance data integrity, reliability, and user experience in form-driven applications. Focused on resolving complex bugs in JavaScript and TypeScript, such as correcting select component behavior in data tables, ensuring accurate CSV exports of nested form data, and preventing data loss in dynamic VM evaluation. Improved file upload flows to be non-blocking and refined component logic for persistent custom values. Emphasized robust unit testing and code refactoring, addressing edge cases in form submissions and component state management to support consistent, trustworthy workflows for both form builders and end-users.
