GitHub's Black Employee Resource Group, Blacktocats, organized their first hackathon event in Africa, the CodeNaija Hackathon 2019, held in Lagos, Nigeria, aiming to empower Black lives in tech and highlight the fast-growing Nigerian open source community. The event drew over 100 mid-level and senior software engineers from more than 800 applicants, with participants working in teams to devise technological solutions to social issues in Nigeria. Ahead of the hackathon, a developer roundtable was conducted in partnership with Ingressive, bringing together developers and social entrepreneurs to discuss the community ecosystem. The event was supported by partners such as Andela, Flutterwave, Microsoft, and M12, who provided resources and sponsorship, underscoring the collaborative effort to connect with and understand the local developer community.
