About

Professional summary

I am a Java backend and full-stack engineer specialising in payment systems, third-party integrations, and reliable financial services. I build production services that connect external platforms, payment providers, and business systems.

I have owned and maintained integrations with approximately 15 payment providers across multiple countries. My experience includes virtual accounts, settlements, payments, real-time webhooks, banking APIs, mobile money services, and reconciliation workflows.

I work primarily with Java and Spring Boot, designing REST APIs, secure authentication flows, asynchronous processing, and resilient transaction systems. I also have working experience with TypeScript, NestJS, React, and Next.js for end-to-end product development.

In my current role, I build integration services that allow retailers and businesses to connect their ERP systems to Moniepoint's inventory platform. I monitor production systems, investigate failures, identify root causes, review code, and deliver fixes through CI/CD pipelines.

I am experienced in building financial products such as wallets, escrow platforms, and cross-border payment solutions. I care deeply about idempotency, ACID-compliant transaction flows, failure handling, code quality, and clear technical communication.

I am also interested in evaluating and improving AI-generated code, particularly in production software environments where correctness, readability, security, and maintainability are critical.

Career history

Backend Engineer, Platforms Team (Moniebook) Moniepoint

I build and maintain integration services that connect retailers' and businesses' ERP systems to Moniebook, Moniepoint's inventory management platform. I design and implement reliable REST APIs using Java, Spring Boot, and NestJS where appropriate for business requirements.

I monitor production integrations with New Relic and Grafana, investigate failures, identify root causes, and deliver fixes. I also review code for correctness, readability, and failure handling, participate in design reviews, and deploy through Jenkins and GitHub Actions CI/CD pipelines.

Backend Engineer (Integrations) Ideation House

I owned payment integrations end to end for a cross-border B2B remittance fintech, integrating and actively managing approximately 15 payment providers across multiple countries. I maintained integrations as provider APIs and business rules changed and resolved production issues escalated by support teams.

I integrated virtual accounts, payments, settlements, and real-time webhooks, while building asynchronous payment processing using Kafka and RabbitMQ. I secured Spring Boot APIs with JWT authentication and role-based access control and contributed to the Java 8 to Java 21 upgrade while preserving backward compatibility.

Backend Engineer PayVerde

I built wallet capabilities for balances, transfers, QR payments, and merchant transactions. I also developed authentication and authorization features for users, merchants, and agents.

I integrated banking APIs, mobile money providers, and SMS/USSD services within a modular Spring Boot codebase. My work focused on building reliable financial functionality and extensible integrations.

Founder ShopSecure

I founded and built an escrow-based commerce platform that enables Nigerians to buy and sell online more safely by holding payments in escrow. I led product direction, system architecture, and end-to-end backend and frontend development.

I designed the escrow workflow, including staged fund release, dispute handling, Paystack payment verification, and webhook processing. The platform was built using Spring Boot, React, Next.js, and Paystack.
