Build small to medium features end-to-end, from the interface through to the data layer, following good coding practices. Improve existing frontend and backend code to make it cleaner, more consistent, and easier to maintain. Document your reasoning, approach, and code decisions to support AI training data quality.

Review peer-contributed code and technical submissions for correctness and clarity. Preferred Qualifications 1+ years of hands-on experience building both frontend and backend applications. Comfortable with at least one frontend framework (React, Vue, or Angular) and one backend stack (Node/Express, Python/Django/Flask, Java/Spring, or similar). Solid understanding of how frontend and backend systems connect through APIs.

Ability to debug issues that cross the frontend/backend boundary. Good documentation and communication skills to explain your technical decisions clearly. Interest in or curiosity about AI and its technical challenges (previous AI experience not required). Originally posted on Himalayas
