Filters 2.0 reimagines search and filtering across Finix's payments platform, powering discovery over the entire product surface. Customer research during the dashboard redesign surfaced a clear demand for better search—but with global search out of scope, I advocated for a focused overhaul of the fragmented logic behind all 240 filters. The effort consolidates inconsistent filter behavior into a unified query model of fields, operators, and values, aligns the experience with users' mental models, and introduces advanced capabilities like nested logic and AND/OR flexibility. It balances deep technical refactoring with close customer collaboration, laying the foundation for future natural language global search while directly impacting net ARR growth.
