Hi, I’m Haruna Auwalu — an Embedded Systems Engineer, Electrical & Electronics Engineer (B.Eng, ATBU Bauchi), and Software Engineer with a strong multi-disciplinary background across hardware, software, and intelligent systems. • Embedded Systems Engineering I specialize in designing and building embedded solutions using C, Arduino, ESP32, STM32 and other microcontroller platforms. My experience includes circuit design, sensor integration, automation systems, and hardware debugging. I am also proficient with simulation and PCB design tools like KiCad and EasyEDA pro. • Electrical & Electronics Engineering (B.Eng, 5 years – ATBU Bauchi) My foundation in Electrical and Electronics Engineering gives me a deep understanding of electronic circuits, digital systems, communication systems, and power principles. This background strengthens my engineering approach and problem-solving mindset. • Software Engineering (ALX Africa – 12 Months) I trained as a Software Engineer with ALX, where I developed strong skills in Python, JavaScript, React, Flask, SQL/MySQL, Git, and Linux/Unix systems. I write clean, scalable code and build efficient full-stack applications. • CAD & PCB Design I design 3D models and enclosures using Autodesk Fusion 360, and I create professional PCB layouts using KiCad, EasyEDA pro, and other EDA tools. My experience covers both schematic design and turning concepts into manufacturable products. • AI & Python Development Recently, I expanded into Artificial Intelligence and Machine Learning, using Python for data analysis, automation, and AI model development. I combine AI with software engineering to build smart, efficient, and modern solutions. • Front-end & Full-stack Development I’m also a front-end developer skilled in React, Redux, JavaScript, and responsive UI/UX design. Combined with my Flask and MySQL experience, I build robust full-stack applications ranging from e-commerce systems to live chat platforms. • Linux & Developer Tools I am highly efficient in Ubuntu, Kali Linux, and shell environments, and I work comfortably with tools like Vim, Emacs, Webpack, and Git for development and automation. • What I Do My portfolio includes: Embedded systems for automation and IoT Full-stack web applications CAD modeling and PCB design AI-powered Python applications Whether it’s designing an embedded system, developing a web app, creating a 3D model, or building an intelligent software solution, I approach every project with creativity, precision, and engineering excellence. Open to freelance and collaboration opportunities — let’s build something great together.
