I'm Onoyima Francis a full stack developer based in Lagos, Nigeria, with 5+ years building the systems that power real products.
My background spans aviation safety platforms, fintech trading systems, healthcare software, Web3 infrastructure and e-commerce across clients in the US, UK, Canada and Scotland. I work best where the problem is complex and the stakes are real.
I'm comfortable across the full stack: PHP, Node.js, Python and Solidity on the backend; React, JavaScript, HTML and CSS on the frontend; MySQL and PostgreSQL for database. I understand authentication, API integration, database architecture and how to build systems that are both secure and maintainable.
I studied Computer Science at the University of Nigeria, Nsukka, where I also led a team building the university's website. I've since worked with startups, remote teams and research institutions delivering software that ships and holds up.
How I Work
-
01
Clarify requirements first. I ask what needs to be built, how it should work, and when it should be delivered.
-
02
Adapt to the project. For solo projects, I often begin with the frontend to validate the user experience. In team environments, I typically focus on backend architecture, APIs, and integrations.

03
Measure twice, ship once. I review and test my work carefully before moving on to the next task.
