What we believe
Proof that you can do the work

Founder, The Data Immersed · Lead Tutor and Instructor
Dabere Nnamani (Annie)
Daberechi "Annie" Nnamani is the founder of The Data Immersed (TDI) and the lead tutor at TDI Hub. Based in Lagos, she is a data analyst, data analytics consultant and AI engineer, and an educator focused on helping Africans break into data and tech.
Annie studied Microbiology, not Computer Science, before moving into data analysis, and she learned in public, documenting her progress as she built her skills. That path shapes how she teaches: practical, step by step, and built for people starting from zero.
Through TDI she has trained learners in Excel, SQL and Power BI, and grown the organisation around three pillars: a community for learning, a consultancy for businesses, and an annual tech summit. TDI Tech Summit 1.0, The Next Digital Revolution: Tech, Ethics, and Society, was held in Lagos in August 2025, followed by TDI Tech Summit 2.0 in July 2026.
Her work increasingly sits where data meets AI. She works as an AI and prompt engineer, closes the TDI Data Analytics Program with a dedicated stage on AI for data analysis, and runs AI Daily, a community for people learning about AI, keeping up with it and finding ways to earn with it. She shares practical data tips, AI insights and career advice online.
Annie also creates resources for learners at every stage: the Data Analytics Starter Pack for beginners, Show Your Work for documenting analysis projects, and Land a Job Faster with AI for job seekers. She writes on Medium about how to become a data analyst.

Student feedback
In their own words
What past TDI students said about learning with us.
“I've learned how to be more systematic. Ann's step-by-step approach and thorough thinking really shaped how I now tackle problems. Her conversations and interactions are top notch, and she's a true goal getter.”
Louis Wemudoi
TDI Masterclass graduate
“The teaching process has been very satisfactory. Every detail is explained in the simplest way possible, making it the most simplified class I've had. Learning from such a thorough and understanding teacher has been a joy.”
God'swill Ajimi
TDI Masterclass graduate
“I loved that everyone is given room to participate and feel comfortable in the learning process. I've greatly improved in my analysis because no one shames you for not knowing or learning at your own pace. Participation is encouraged, which makes learning faster.”
