Ake Ovie
Data Scientist · 9 years Python
Ovie has shipped Python in production from His University days and worked with Nigerian fintech startups. He has been teaching programming online since 2019 and is known for making abstract concepts feel obvious.
Frequently asked questions
What Python knowledge do I need before starting?+
You should be comfortable with Python basics — variables, loops, functions, and working with lists and dictionaries. If you're unsure, take Python for Beginners first.
Is there a lot of maths involved?+
Yes, but we teach the intuition before the equations. You don't need a maths degree. You need curiosity and the willingness to ask questions. We go at a pace that works for the cohort.
Will we work on Nigerian datasets specifically?+
Every project uses real Nigerian data: real estate prices, fintech transaction records, and economic indicators. The problems feel familiar, which dramatically accelerates learning.
How is this different from a free YouTube course?+
Live instruction, code review, human feedback on every assignment, and a cohort of people going through it alongside you. That combination of accountability and community is nearly impossible to replicate on your own.
Do I get a certificate?+
Yes. A verifiable Oak Forge Academy certificate is issued after your capstone presentation in Week 16.
How does payment work?+
This course is full payment upfront at ₦200,000 via Paystack. The monthly school-fee plan becomes available on programs priced at ₦300,000 and above — which includes our advanced full-school programmes launching later in 2025.
Will this course prepare me for roles at Nigerian companies?+
That's the explicit goal. The capstone panel includes working data scientists from Nigerian tech companies. Graduates have gone on to roles at Paystack, Interswitch, and several Series A startups.
