In the bustling tech hubs of Nigeria, where innovation meets ambition, Akoche Ochefu has quietly become a linchpin in the nation’s artificial intelligence revolution. As an AI Expert Annotator at Mindrift, Ochefu spearheaded a groundbreaking initiative to refine data for indigenous AI models, directly fueling the development of applications that now underpin government services and economic growth. His work, aligning with Nigeria’s National AI Strategy, has elevated data quality to new heights, delivering scalable impacts that position the country as Africa’s emerging AI powerhouse.

Launched in mid-2024 amid Nigeria’s push for digital sovereignty, Ochefu’s Data Precision for AI Advancement (DPAA) project targeted the annotation of vast datasets in local languages like Yoruba, Igbo, and Hausa. Drawing from his sociology degree and certifications in AI-augmented professional development from ALX Africa, Ochefu recognized a critical void: global AI models often faltered on African contexts due to biased or inaccurate training data. “AI isn’t just code; it’s about reflecting real lives,” Ochefu said during a recent panel at the National Centre for Artificial Intelligence and Robotics (NCAIR) in Abuja. “By annotating with cultural nuance, we’re building tools that serve Nigerians first.”
Under DPAA, Ochefu led a team that labeled over 500,000 data points; text, audio, images, and videos, boosting model accuracy by 35% for local language processing, according to Mindrift’s internal audits. This precision directly supported the Federal Ministry of Communications, Innovation, and Digital Economy’s rollout of N-ATLAS, Nigeria’s indigenous Large Language Model. Integrated into government platforms, N-ATLAS now powers AI-driven services like automated tax filings at the Federal Inland Revenue Service and identity verification at the National Identity Management Commission, reducing processing times by 40% and cutting fraud incidents by 25%.

Scaled nationally, DPAA dovetails with the 3 Million Technical Talent (3MTT) program, one of the world’s largest digital upskilling efforts. Ochefu’s annotated datasets have trained over 150,000 participants in AI applications, enabling them to develop localized tools for agriculture and healthcare. In partnership with Microsoft’s AI National Skills Initiative, which has already equipped 350,000 Nigerians and aims for one million by 2027, his work has extended to public sector modernization. For instance, AI chatbots for citizen queries in indigenous languages, refined through Ochefu’s annotations, handle 2 million interactions monthly across government portals, enhancing accessibility in rural areas.
Ochefu’s team transcribed and tagged audio from medical consultations in local dialects, creating datasets for AI diagnostic tools. Deployed via the Society for Family Health, where Ochefu previously supervised operations; these applications have scaled to 500 clinics, improving diagnostic accuracy by 30% and serving 1.2 million patients annually. “It started with tagging patterns in speech,” Ochefu noted. “Now, it’s saving lives by making health advice available in languages people trust.”

DPAA supports the National AI Strategy’s pillars of ethics, inclusivity, and sustainability, as outlined by NITDA Director General Kashifu Inuwa. The project received N50 million in grants from the Nigeria Artificial Intelligence Research Scheme (NAIRS), ensuring responsible data handling compliant with data protection laws. Challenges, such as initial data scarcity in underrepresented languages, were overcome through collaborations with universities like Benue State University, Ochefu’s alma mater, where he mentored sociology students in annotation techniques.

By 2026, N-ATLAS and related AI tools are projected to add N1.5 trillion to Nigeria’s GDP through efficiency gains, per PwC estimates. Ochefu’s initiative has also spurred 20 startups, funded under government schemes, to build on his datasets for fintech and e-commerce apps.
A Benue native with a diverse career spanning cooperatives oversight and cybersecurity training from Google and Cisco, Ochefu embodies Nigeria’s tech ascent. As the country eyes GITEX 2026 to showcase its AI prowess, his work stands as a testament to how individual expertise, harnessed at scale, can propel national transformation.
