Testimonials

  1. Redeem was an Outreachy intern on a UI Uplift project for ODK-X, I was one of the mentor team. Redeem showed leadership and community spirit during the application process by encouraging fellow applicants, providing help to others to get started, and providing technical advice to anyone who needed it. As a selected intern on the project, Redeem was well organised, collaborative, and an active communicator on project progress. Redeem learned quickly, and showed strong commitment to submit changes and pull requests to help achieve successful project outcomes.
    It was great to work with Redeem and I am pleased to recommend him.
