Senior Software Engineer — Agentic Development & Production Systems

Building and operating reliable software systems for over a decade

Abuja, Nigeria · UTC+1 · Open to remote Senior / Lead Backend Engineer roles

Engineering Profile

Senior Software Engineer with over 10 years of experience building, scaling, and operating business-critical production systems across organizations in the US, Canada, Europe, and Africa.

I have over five years of experience working remotely with US-based engineering organizations through Andela, collaborating with distributed teams and delivering production software across different business environments.

Experienced in taking products end to end—from business requirements and system architecture through implementation, testing, deployment, and production operations.

My experience spans financial systems, renewable energy marketplaces, verification platforms, government technology, enterprise applications, and system integrations.

Increasingly using AI-assisted and agentic software development workflows to accelerate delivery while maintaining strong engineering, architecture, testing, and production standards.

I work particularly well where a business needs to turn a real operational problem into a reliable production system, or where an existing system needs to be organised, stabilised, or evolved.

Systems Expertise

Background

I hold both a Bachelor's and Master's degree in Computer Science and have spent over a decade designing and operating production systems across fintech, government technology, renewable energy marketplaces, verification platforms, and enterprise applications.

Over five years of working remotely with US-based engineering organizations through Andela gave me extensive experience operating within distributed teams, communicating clearly across time zones, and taking ownership of production work.

My earlier work in banking and enterprise systems shaped my approach to reliability, financial correctness, security, and operational workflows.

This experience shaped how I design software: explicit system behaviour, stable operational foundations, and architectures that remain maintainable as teams and products evolve.

Highlighted Experience

TrustVerify

Remote · 2025 - Present

Lead Engineer — Business Verification Platform

Led the technical planning and development of TrustVerify, a platform enabling businesses to establish trusted identities and verifiable credentials.

Used agentic software development workflows with Codex, GSD, OpenRouter, and MCP to take the project end to end—from requirements and system architecture through implementation, testing, and production readiness.

Defined the system architecture, API contracts, and data models upfront, guiding implementation across the platform and maintaining clear boundaries between system components.

Designed the verification lifecycle as explicit system states, ensuring transitions could not be skipped, replayed, or partially applied under concurrent requests.

Worked across backend architecture, APIs, integrations, testing, and production concerns, with a focus on building a system that could remain reliable as usage and requirements grew.

Mentored engineers and promoted structured backend architecture, testing practices, and maintainable system design.
