Worked on moltbot/moltbot to enhance billing reliability by improving error handling for billing-related failures. Developed a targeted solution in TypeScript that recognizes the Poe 402 'used up your points' error and triggers a robust fallback mechanism, ensuring users are not exposed to raw error messages and billing workflows continue smoothly. Emphasized code quality through unit testing and collaborative development, with changes delivered via a squash merge and peer review. This work reduced user confusion and improved the reliability of billing paths, contributing to potential reductions in support tickets and a more seamless user experience within the billing system.
