Frontend and backend features for a white-label payments platform integrated with a major banking partner serving multiple banks.

• Implemented check cancellation and refund workflows, working with the banking partner and internal teams to resolve API contract gaps and represent asynchronous payment states.
• Refactored payment synchronization to fetch additional refund details only for qualifying transactions, limiting external API calls while preserving downstream interfaces.
• Built synchronization flows using AWS Lambda and SQS, extending established serverless patterns through internal infrastructure tooling.
• Built partner-specific payment timelines and status displays through frontend plugins and APIs, including support for migrated checks with incomplete lifecycle data.

Interactive tools for a platform that automated credit-decision workflows.

• Independently designed and built a React and TypeScript formula editor using Lexical, with a custom parser converting expressions and variable references into abstract syntax trees.
• Built conversational formula creation end-to-end using LangChain, transforming structured AI output into the existing formula-processing pipeline.
• Led adoption of reducer-based state management in a complex workflow editor, separating user actions from state-transition logic.
• Introduced Storybook for isolated component development and review, creating the initial integration and stories for collaboration with product and design.

• Built a custom financial data visualization tool using React, D3.js, and pandas.
