Hi, I'm Haruna! I'm a front-end developer with a passion for building clean, responsive, and user-friendly web applications. My core stack includes React, Redux, and JavaScript, with a strong focus on UI/UX design principles. I complement this with back-end expertise in Flask and MySQL, allowing me to develop robust full-stack solutions. My engineering background sets me apart. With hands-on experience in C programming, data structures, and electronics, I bring a low-level, performance-oriented mindset to software development. I'm proficient in embedded systems work using Arduino, C, MATLAB, and circuit design in Proteus/Kicad I am highly efficient in Linux/Unix environments, including Ubuntu and Kali, and am adept at using powerful editors like Vim and Emacs for development and system administration tasks. My project portfolio is diverse, spanning from e-commerce platforms and live chat applications to embedded systems for automation. Whether it's crafting a seamless user interface, optimizing system performance, or designing an innovative electronics solution, I apply a creative and analytical problem-solving approach to every challenge. Open to freelance opportunities—let’s build something great together

Designed and developed a smart solar flood lamp using a microcontroller. The lamp operates on a time-based schedule, which can be adjusted using an infrared remote. It can also synchronize with sunrise and sunset for automatic operation. A PIR motion sensor enhances security by detecting movement, and an audible alert sounds when the remote is used. This project combines energy efficiency, automation, and user control for optimal performance. https://github.com/hancho6319/ATBUproject4solarfloodlamp
