At GlobalLogic, I designed and implemented a reusable React filter builder for a healthcare security product. It supports nested AND/OR groups, dynamic operators, and field-specific inputs through a recursive data model.

I also refactored legacy code, including a 1,000+ line component, into a more maintainable structure. At EPAM Systems, I took on the Frontend Lead role while remaining hands-on, creating interactive research visualizations and recursive logic for hierarchical tables.
