This is a UNV contract. More about UNV contracts.

UNICEF and the Learning Passport team works to provide uninterrupted education for every child affected by crisis – especially girls, children with disabilities, internally displaced children, refugees and migrants.

We help children develop skills to cope with the trauma of crisis, and supply them with learning spaces that are safe, child-friendly and equipped with water and sanitation facilities. Our work builds capacity by training teachers, supplying learning materials and supporting Governments to reduce the risk of disaster.

We’re looking for 2 volunteers to help review and improve an open source project built mainly in C#/.NET, with some JavaScript/TypeScript, CSS, T-SQL, and PowerShell. The work includes:

  • Reviewing code on GitHub

  • Suggesting improvements and contribute to the development of the LP2.0 roadmap

  • Contribute to FE architecture discussion, review component library, accessibility, performance.

  • Estimating the effort for new features and highlighting risks or dependencies

  • Support with documentation efforts

  • Using tools like GitHub Copilot, Copilot Chat/Agents, GitHub Spark, or Replit Ghostwriter to explore, explain, and even prototype code features

  • Submitting fixes, improvements, or small features via pull requests
