Backend engineer specializing in scalable, high-performance enterprise applications.
NigeriaWhat I'm looking for
I am a backend software engineer with strong experience designing and building high-volume, low-latency enterprise applications using Java and JavaScript ecosystems.
I've served as a consultant and founding-team engineer, delivering APIs, risk-management systems, payment and order management features, and performance optimisations across multiple startups.
I prioritise collaboration, design thinking, and developer best practices — including TDD, CI/CD, code reviews, and mentoring — to produce secure, maintainable systems.
My background spans cloud deployments, microservices, containerization, messaging systems, and database optimisation, and I consistently contribute to process improvement and stakeholder-aligned delivery.
