Over the last decade, Oluwasegun Mosaku has worked at the intersection of enterprise software, digital banking, cloud technologies and entrepreneurship, contributing to projects in Nigeria, Germany and the United Kingdom.
From helping build Sterling Bank’s OneBank platform to developing industrial Internet of Things (IoT) solutions and mentoring hundreds of aspiring software engineers, his career reflects the growing global influence of African technology professionals.
In this exclusive interview with Techeconomy, Oluwasegun Mosaku, a software engineer, entrepreneur and technology community leader whose work spans enterprise software, digital banking, cloud technologies, industrial IoT and mentorship initiatives across Nigeria and the United Kingdom, speaks about his journey, the future of AI, why mentorship matters as much as engineering, and what Africa must do to produce world-class technology leaders.
TE: You studied Electrical and Electronics Engineering but built your career in software engineering. What inspired that transition?
Oluwasegun Mosaku: Engineering has always been about solving problems for me. While studying Electrical and Electronics Engineering at the University of Lagos, I realised that software was becoming the driving force behind innovation across every industry. Whether it’s finance, healthcare, manufacturing or logistics, software sits at the centre of transformation.
That realisation changed my career trajectory. I became fascinated by how a single software solution could improve efficiency for thousands, or even millions, of people simultaneously. It wasn’t just about writing code; it was about designing systems capable of changing how organisations operate and how people interact with services.
That perspective has guided every role I’ve taken since.
TE: Looking back, which project do you consider the defining moment of your career?
Oluwasegun Mosaku: Every project has taught me something different, so it’s difficult to choose one.
Working on Sterling OneBank was particularly significant because it demonstrated how digital banking can improve financial inclusion at scale. Seeing a platform evolve into one used by more than a million customers reinforced the importance of building reliable, secure and user-centred technology.
Earlier in my career, developing Sophia ERP also left a lasting impression. The idea behind that project was simple: many small businesses couldn’t afford enterprise software. If technology truly enables economic growth, then SMEs shouldn’t be excluded simply because of cost.
That philosophy still influences how I think about technology today.
TE: Your work spans banking, logistics, manufacturing, cloud computing and enterprise software. Has working across different sectors shaped your approach?
Oluwasegun Mosaku: Absolutely. Different industries face different operational challenges, but they often share similar technology problems.
Banks require secure and scalable systems. Manufacturers need connected industrial platforms. Logistics companies depend on real-time operational visibility. Businesses everywhere need better data.
Working across multiple industries has taught me to focus less on technology itself and more on understanding the business problem first. Technology is only valuable when it solves a real problem.
TE: You later contributed to industrial IoT projects in Germany. What did that experience teach you?
Oluwasegun Mosaku: It expanded my understanding of engineering excellence. Industrial software requires an entirely different level of precision because the systems interact with manufacturing environments where reliability is critical.
Working on IoT solutions built on Microsoft Azure exposed me to global engineering practices, cross-functional collaboration and large-scale enterprise architecture.
It reinforced something I’ve always believed: African engineers can compete globally when given the opportunity.
TE: Today you’re based in the United Kingdom. How would you compare the UK and Nigerian technology ecosystems?
Oluwasegun Mosaku: They’re at different stages of maturity, but they’re also complementary. Nigeria has incredible entrepreneurial energy. Engineers are constantly finding innovative ways to solve problems despite infrastructure challenges.
The UK offers mature systems, structured engineering processes and strong investment in research and development.
I believe the greatest opportunity lies in connecting both ecosystems.
Nigerian engineers bring creativity, resilience and problem-solving ability, while the UK provides access to global markets, advanced technologies and established enterprise environments.
The future belongs to collaboration rather than competition.
TE: Artificial Intelligence is changing software development rapidly. Should engineers be worried?
Oluwasegun Mosaku: I don’t think engineers should fear AI. They should learn it. Every technological revolution changes how engineers work. Cloud computing did. Mobile computing did. Now AI is doing the same. AI will automate repetitive tasks, but creativity, architecture, critical thinking and business understanding remain human strengths.
Engineers who embrace AI will become significantly more productive than those who resist it.
TE: You’ve also become known for mentoring software engineers. Why is that important to you?
Oluwasegun Mosaku: Because somebody invested time in helping me. No one succeeds entirely alone. Technology communities grow when experienced professionals deliberately create opportunities for the next generation. That’s one of the reasons we co-founded the Nigerian Software Engineers in the UK Community.
We wanted people relocating to the UK to have access to mentorship, networking and practical career advice. When people succeed, the ecosystem becomes stronger.
TE: Beyond engineering, you’ve also founded technology businesses. What motivates your entrepreneurial journey?
Oluwasegun Mosaku: Entrepreneurship allows you to solve problems that traditional employment may not always address. With Wealth World Solutions, we’re building enterprise software that simplifies business operations. With Swadex, the focus has been financial discipline and community savings. In both cases, technology is simply the tool. The real objective is improving how people and businesses operate.
TE: Many young African engineers want international careers. What advice would you give them?
Oluwasegun Mosaku: Focus on fundamentals. Programming languages change. Frameworks change. Technologies evolve. Problem-solving doesn’t. Build strong engineering principles. Learn cloud technologies. Understand distributed systems. Develop communication skills. Most importantly, never stop learning.
The engineers who succeed globally are usually the ones who remain students throughout their careers.
TE: What role do African software engineers have in shaping the global technology industry?
Oluwasegun Mosaku: A significant one. For too long, Africa has been viewed primarily as a consumer of technology. That narrative is changing. Today, African engineers are building global products, leading engineering teams and solving complex technical problems across every continent.
I believe the next decade will see even greater African influence—not just through outsourcing, but through innovation, entrepreneurship and intellectual leadership.
We should aspire not only to work for global technology companies but also to build globally recognised technology companies from Africa.
TE: If you could solve one technology challenge over the next ten years, what would it be?
Oluwasegun Mosaku: Talent development. The world doesn’t have a shortage of technology opportunities. It has a shortage of well-prepared technology professionals.
If we invest consistently in mentorship, education and practical engineering experience, we’ll unlock innovation that extends far beyond software. We’ll create businesses. We’ll strengthen economies. We’ll improve lives.
Ultimately, technology isn’t about computers. It’s about people. And when people have the right opportunities, technology becomes one of the most powerful tools for creating lasting impact.
