How She Leads: Oluwatoyin Aromokeye’s blueprint for growth, security, and product integrity

Growth is often celebrated in numbers, but for any product to truly scale, it must grow with intention. Systems need to withstand pressure, and trust must be built into every layer. 

Behind many high-performing digital products are women making deliberate decisions about what users never see: how payments move, how failures are handled, how discrepancies are resolved, and how fraud controls are designed to protect systems without shutting out legitimate customers.

That kind of work defines the career of Oluwatoyin “Toyin” Rebecca Aromokeye. At Dot.ai (Dot Financial Inclusion Technologies Limited), Toyin worked as a Product Manager during a period of rapid expansion and increasing transaction volume.

She helped drive the delivery of an agency banking platform that onboarded over 10,000 customers within three months. At the same time, the company’s mobile and agent-facing products were supporting roughly 200,000 secure transactions each day.

Her work centred on reliability at scale, strengthening transaction integrity through reconciliation processes, risk-aware workflows, and product decisions designed to perform under real-world pressure.

Today, as a Portfolio Product Manager at Boost Mobile, Toyin collaborates across engineering, analytics, compliance, and customer teams to develop commerce features and implement fraud prevention strategies.

Read the excerpts from a chat about her work:

What first inspired you to pursue a career in technology and product management?

I was inspired by the opportunity to create technology-driven products that operate at scale and meaningfully impact how people access and interact with financial services.

Product management allowed me to take ownership of complex systems from strategy through execution and to be directly accountable for product success, adoption, and long-term value creation in regulated and high-impact environments like fintech.

How did your time at Dot.ai shape your understanding of fintech in Africa?

My work at Dot.ai deepened my understanding of the structural and regulatory realities of fintech in Africa.

I gained firsthand experience designing products for fragmented payment infrastructures, diverse regulatory frameworks, and rapidly scaling user bases.

This experience sharpened my ability to build resilient, compliant, and scalable fintech solutions that align global best practices with local market realities, an approach that continues to inform my work today.

Dot.ai has cited major scale numbers from that period. What did “scale” look like in practice?

Scale meant building for operational reality.

Dot.ai leadership has documented key outcomes from that period, including onboarding 10,000 customers within three months on a B2B agency banking product, supporting around 200,000 secure transactions daily, and processing over 80 billion Naira in transactions within four months.

For product teams, that means you cannot rely on assumptions. You have to design for failure paths, monitoring, support workflows, and reconciliation from day one.

In your view, how has technology changed the way people in Nigeria and Africa access financial services?

Technology has fundamentally transformed financial inclusion across Nigeria and Africa by decentralising access to financial services.

Digital payments, mobile banking, and identity-based financial systems have enabled individuals and small businesses to transact, save, and access credit without reliance on traditional banking infrastructure.

This shift has accelerated economic participation, reduced transaction friction, and improved transparency across the financial ecosystem.

Can you share an example of how you used technology to solve a complex problem in payments or fraud prevention?

I contributed to initiatives aimed at improving the reliability and transparency of digital payment experiences by helping define product workflows across multiple systems and partners.

One example involved addressing inconsistencies in how transactions were processed and communicated to customers, which required close coordination between engineering, operations, and customer-facing teams. 

By refining end-to-end payment flows and clarifying system responsibilities, we improved transaction consistency and reduced customer confusion, while ensuring alignment with platform constraints and compliance expectations.

What has been the toughest challenge you’ve faced in building reliable payment systems, and how did you overcome it?

One of the most complex challenges I faced was maintaining system reliability across interconnected payment networks, third-party providers, and compliance constraints.

I addressed this by driving cross-functional alignment, clarifying ownership across teams, and helping establish processes for monitoring and handling failure scenarios.

These measures improved system resilience and reduced the impact of incidents in high-volume, mission-critical payment environments.

What personal strengths do you rely on most when leading product teams under pressure?

I rely heavily on strategic clarity, data-driven decision-making, and calm execution under pressure. In high-stakes environments, I focus on prioritisation, clear communication, and aligning diverse teams around shared outcomes.

These strengths enable me to lead effectively during incidents, regulatory changes, or accelerated delivery timelines.

At Boost Mobile, how do you balance working across engineering, compliance, and customer teams to deliver secure commerce features?

At Boost Mobile, I play a central role in aligning engineering, compliance, and customer experience teams to deliver secure, large-scale commerce platforms in a highly regulated environment.

I lead cross-functional strategy from inception through launch, translating complex regulatory obligations and evolving risk requirements into clear, scalable product architectures. 

By establishing shared accountability, rigorous governance frameworks, and continuous feedback loops with customer teams, I ensure security and compliance are embedded into the product lifecycle, not added as an afterthought.

This approach enables us to move quickly while safeguarding customer trust, maintaining regulatory adherence, and supporting millions of secure transactions.

What do you aim to achieve in your career over the next few years, both personally and for the fintech industry?

Over the next few years, I aim to continue growing as a product leader focused on fraud prevention and trust-driven product design across highly regulated digital platforms.

Personally, my goal is to deepen my impact in building systems that proactively manage risk, protect users, and scale securely. 

From an industry perspective, I plan to contribute through thought leadership, advisory engagement, and cross-industry collaboration, applying fraud-prevention and governance best practices from regulated commerce and digital ecosystems to support the development of more trusted, inclusive, and resilient platforms.

What advice would you give to someone who wants to build a career in product management within fintech?

I would advise aspiring product managers to develop a deep understanding of financial systems, regulations, and risk management alongside strong technical and user-centric skills.

Fintech rewards those who can navigate complexity, lead cross-functional teams, and deliver solutions that prioritise security and trust as much as innovation.
