What I'm looking for

I'm looking for remote or international backend engineering opportunities focused on scalable systems, fintech, SaaS, or AI/LLM-powered infrastructure, where I can build reliable APIs, services, and technical products.

I built and operate OffCampus.ng, a live student housing marketplace connecting students with property owners and agents. I own its backend architecture, deployment, debugging, and technical product decisions for a product serving 1,000+ active users and 24,000+ page views.

I've developed production Go services and REST APIs at ServiceNow Innovato Nigeria, improving database query performance by approximately 40% through indexing and query optimization. At Tankar Solutions, I built Node.js services for a financial advisory platform serving 1,000+ clients and advisors, reducing server load by about 20% and improving API response times by 30%.

I enjoy building reliable APIs, transactional payment workflows, authentication systems, and scalable distributed services using Go, Node.js, PostgreSQL, MySQL, MongoDB, Redis, and AWS. I'm particularly interested in fintech, SaaS, and AI/LLM-powered backend infrastructure.
