About

Hi, I'm Chukwuamaka Friday, a mobile developer based in Nigeria with a strong focus on building scalable and user-centric applications using Flutter. My expertise extends into hardware integration with Arduino Express and web development with Vue, enabling me to create versatile, cross-platform solutions

I thrive on solving complex problems with clean, efficient code and continuously explore emerging technologies to deliver modern, high-quality products. Outside of development, I enjoy music composition, where I apply the same creativity and attention to detail that I bring to my work.

Lately, I’ve been diving into cutting-edge technologies, continuously expanding my skillset and staying ahead of trends to deliver modern, high-quality solutions.

Here are a few technologies I've been working with recently:

  • Flutter
  • Firebase
  • Node.js
  • Vue
