Developed foundational features for the HackBeanpot/core application portal, focusing on portal scaffolding and a robust authentication system. Leveraged JavaScript, TypeScript, and Next.js to implement email-based sign-in, session management, and protected routes, establishing secure user access. Introduced GET and POST authentication route skeletons to support future API development, while prioritizing maintainability through automated code formatting and linting adjustments. The work emphasized both backend and frontend development, ensuring a scalable architecture for subsequent features. By improving code consistency and readability, the project laid a strong technical baseline, enabling faster and safer delivery of new capabilities without addressing bug fixes during this period.
