Tech Tackle is an annual coding boot camp and hackathon program teaching adolescent girls design thinking, coding and research so they can use the skills to innovate tech solutions to critical social issues affecting children, particularly girls. The Tech Tackle 2019 theme is ''Promoting Peaceful and Inclusive Societies for Sustainable Development, Providing Access to Justice for All and Building Effective, Accountable and Inclusive Institutions at All Levels.'' The Tech Tackle 2019 theme aligns with the Education for Justice Initiative of the United Nations Office of Drugs and Crime (UNODC) and is working with public secondary school girls to innovate tech solutions to issues of the rule of law and the justice system in Nigeria. The Girls Hackathon 4 Justice innovated tech solutions inspired by phenomenal girls from ten (10) public secondary schools in the Federal Capital Territory.

Girls Voices Initiative launched the Tech Tackle 2019 program in support of the Education for Justice (E4J) Initiative of the United Nations Office for Drugs and Crime (UNODC), to host the ‘Girls Hackathon 4 Justice’ and explored technology solutions to the prescribed challenges of UNODC's Hackathon for Justice program. The Tech Tackle Program has trained 50 adolescent girls in design thinking skills, coding skills, and research skills. A total of ten (10) school teams were tasked to innovate technology solutions across some selected challenges under the Hackathon for Justice Initiative including: Counter Terrorism, Human Trafficking, Transnational Organized Crime, Crime Prevention and Criminal Justice, and Corruption (Inscribe the Bribe - an iReport solution to stop bribery). The girls teams each pitched their technology solutions to these challenges at a competition event where the winning teams were selected by an expert panel of judges and awarded. Participants from relevant government institutions and agencies, media, development partners, civil society organisations and diplomatic community graced the event. The event was filled with indigenous, mind blowing technology solutions, profferred by the girls.
