About Me

Full-Stack Developer (PHP, Laravel, Flutter) | eCommerce Operations & Automation

I'm Chinonso Michael Mmuoma, a full-stack developer based in Nigeria and working remotely, with professional experience dating back to 2008. I build web applications, database-driven portals, Flutter mobile apps, REST API integrations and payment features, mainly in PHP, Laravel, MySQL, JavaScript and Dart, and I deploy and maintain them on Linux and Docker.

I also bring six years of remote eCommerce operations with a US-based team: Amazon listings and FBA, A+ content, Magento catalog management, inventory data and reporting in monday.com and Jira. That mix means I understand both the code and the business process it has to support.

Recent work includes the Watchman Campus Fellowship web and mobile platforms (role-based access, payments, reporting), a Laravel real-time video production platform (LiveKit/WebRTC), school admission portals, and Gatherly, an event ticketing and fundraising app.

I'm open to remote full-time, contract and freelance roles in software development, SaaS and eCommerce automation. On Freelancer.com I hold a 4.9-star rating from 136 reviews.
