Justice Opoku Nontwiri | Full-Stack Developer & AI Enthusiast

01. About Me

Hey! I'm Justice, a passionate technologist based in Ghana. My journey in technology started with a simple curiosity about how things work, which evolved into a deep passion for creating solutions that make a real difference.

I specialize in building innovative applications that solve real-world problems. From developing CropGuard, an AI-powered crop disease detection system for African farmers, to creating J-Assist, a personal AI assistant, I'm driven by the impact technology can have on communities.

Currently, I'm honing my skills at PRESEC-Legon, exploring the intersection of AI, web development, and robotics. I'm particularly interested in how emerging technologies can empower African communities and drive sustainable development.

Here are some technologies I've been working with recently:

Python & Machine Learning
JavaScript (React, Node.js)
HTML & CSS
TensorFlow & PyTorch
Arduino & IoT
UI/UX Design
