Worked on maintaining stability and consistency in CAPTCHA-related workflows for the WhiteboxHub/wbl-frontend and wbl-backend repositories. Focused on restoring previous functionality by reverting changes that had altered CAPTCHA token naming and removed essential verification and fee collection routes. Used explicit revert commits to ensure traceability and facilitate future maintenance or rollback needs. Leveraged skills in API development, FastAPI, React, and SQLAlchemy, working primarily with Python and JavaScript. The approach prioritized minimizing integration risk and preserving business logic, resulting in improved alignment between frontend and backend systems and maintaining a seamless user verification and monetization experience across the platform.
