Onyema.
I build products from idea to production — engineering rigour and product instinct working in tandem, shipping remotely.
Who I am
“I don't just write code — I build products that work for the people who use them.”
I'm a Software Engineer and Technical Project Manager based in Nigeria, focused on building full-stack products that are technically sound and genuinely useful. I care about the full picture — from system design to user experience to delivery.
My experience spans building solo and in teams, shipping to production, iterating based on feedback, and keeping stakeholders aligned throughout. I work best at the intersection of engineering and product.
I hold a First Class BSc in Computer Science from UCLan Cyprus, and I'm open to select freelance work and interesting collaborations.
Where I've worked
Sole developer of a custom conference and event web app. Worked directly with HR and stakeholders through iterative feedback cycles, shipped to production, and received strong feedback from attendees.
Two-person team delivering a responsive site for an in-house game title. Led the entire frontend track — performance, component architecture, and cross-device QA — while coordinating directly with the game team on design and timelines.
Final Year: Full-stack employability events platform.
