Dotun Adekunle: At OPay, Technology Remains Our Engine for Driving Financial Inclusion across Africa

In a recent interview with Sunday Ehigiator, Dotun Daniel Adekunle, the Chief Operating Officer and Chief Technology Officer of OPay, emphasized that technology remains the core of the company's mission to broaden financial inclusion across Africa. Leveraging artificial intelligence, advanced security systems, and digital infrastructure, OPay strives to provide fast, secure, and seamless financial services to its growing user base of tens of millions.

The company's scalable architecture is built on a distributed, microservices-based platform where each service—wallets, transfers, cards, bill payments, and agent banking—operates independently, allowing for focused scaling during peak times without affecting other services. Three guiding principles drive this architecture: redundancy at every level to eliminate single points of failure, asynchronous processing to ensure that one product's spike doesn't slow down another, and relentless performance engineering to keep latency in milliseconds.

While customers are more concerned with trust, the platform's architecture is designed to uphold that trust at scale. System downtime can severely damage customer confidence in digital banking. To ensure high system availability, business continuity, and operational resilience, OPay implements redundant infrastructure across multiple availability zones, progressive software rollouts, real-time monitoring with automatic failover, and live disaster recovery drills.

Their current availability stands at over 99%, with a particular focus on transaction speed during peak hours.

Cybersecurity is a constant threat, and OPay takes a proactive approach to protect customer data and financial transactions. Security measures are integrated into the platform from the beginning, including advanced threat detection, encryption, penetration testing, industry certifications, and the well-known nine OPay security features for frontline customer protection. Additionally, OPay invests significantly in staff, merchant, agent, and customer cybersecurity awareness to combat social engineering threats.

Artificial intelligence and machine learning play a crucial role in detecting and preventing fraud in real-time. OPay's fraud engine scores each transaction in milliseconds using hundreds of signals, such as behavioral patterns, device fingerprints, transaction velocities, and habit deviations. Graph-based analysis helps identify and dismantle networks of fraudulent accounts, while the system is designed to ensure that legitimate transactions remain unaffected.

Innovation and speed are maintained without compromising platform stability or customer protection. OPay integrates security reviews and threat modeling into the product development pipeline, utilizing automated testing, security scanning, and staged rollouts as essential checkpoints. This approach has enabled the company to release products more quickly while enhancing overall platform stability.

As Nigeria's financial ecosystem evolves rapidly, OPay adapts its technology infrastructure to comply with changing regulatory requirements while preserving seamless customer experiences. OPay sees regulators as partners and actively participates in working groups, such as those behind the Payments System Vision 2028. The company's compliance logic, KYC tiers, transaction limits, screening, and reporting are managed through configurable services, making it easier to adapt to regulatory changes without disrupting the customer experience.
