When Oyinlola Abolarin graduated with a degree in geology, he never imagined his career path would lead him into the heart of Africa’s booming fintech sector.
Today, at just 29, he is a senior software engineer credited with helping to build some of the continent’s most reliable and widely used digital financial platforms.
Abolarin’s unconventional journey into technology began during his National Youth Service at the National Business and Technical Examinations Board (NABTEB), where he worked on digitizing examination processes.
That experience, he said, sparked a passion for solving inefficiencies through technology.
His first real break came at CMC Interiors, where he digitized the company’s operations, replacing paper-based systems with custom-built platforms that boosted efficiency by nearly 40 percent.
“Suddenly, what used to take three phone calls and two days could happen with a few clicks,” he recalled.
From there, Abolarin honed his skills at Mactavis Digital, delivering more than ten end-to-end products, from websites to mobile applications.
His mastery of WordPress for high-traffic African businesses and his focus on scalability laid the foundation for the fintech engineering challenges that would follow.
He later joined Africa Prudential in a frontend engineering role before moving to Africhange, a major remittance platform.
At Africhange, his focus shifted to speed, reliability, and trust critical factors in digital financial services.
His leadership in architectural design and performance optimization led to faster load times, a 45 percent reduction in app crashes, and a 25 percent boost in customer retention.
“In African fintech, trust is everything,” Abolarin said in a recent interview. “When someone is sending money to family, the app can’t crash. If it feels unreliable, they’ll go back to cash or traditional transfers.”
Working under Africa’s unique constraints from patchy internet connections to older mobile devices, Abolarin says African engineers are forced to innovate beyond Silicon Valley standards.
“We were building apps that had to work perfectly on a three-year-old Android phone with a spotty 3G connection. That’s a much harder problem than optimizing for fast networks.”
Beyond coding, Abolarin is passionate about mentorship and team culture. At Africhange, he helped junior engineers grow into confident developers, boosting team productivity by up to 80 percent.
“Good code reviews and mentorship don’t just improve projects, they build stronger engineering cultures,” he explained.
His contributions extend to security and compliance, where he has integrated robust authentication systems and flexible architectures to adapt to Africa’s fast-changing regulatory landscape.
“In fintech, you can’t move fast and break things. You have to move fast and not break anything,” he said.
Looking ahead, Abolarin envisions African fintech not as an imitator of global models but as a pioneer of uniquely African solutions.
“We’re building digital tools under tougher conditions, but the solutions we create here can work anywhere in the world,” he said.
When he’s not engineering cross-platform applications, Abolarin spends time mentoring upcoming developers and contributing to open-source projects.
For him, Africa’s digital economy is still in its early stages and building its technical backbone is not just a job, but a responsibility.
