About

Hi, I'm Friday Chukwuamaka Kareen, a mobile developer based in Nigeria with a deep passion for solving problems through innovative solutions. Whether it’s crafting clean, efficient code or finding the perfect balance in a chord progression, I thrive on challenges that push me to think creatively.

While my primary expertise lies in Flutter, I also work with Arduino Express and Vue from time to time, extending my development skills into hardware projects and web interfaces. This diversity in my work allows me to create unique, integrated solutions that blend both mobile and interactive systems.

Beyond development, I have a strong interest in music, and I find joy in composing and exploring chord progressions in my free time.

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
  • MongoDB
  • Arduino
