About me

Hi! My name is Denny Mario. I’m a passionate and adaptable person with a strong interest in technology, education, and everyday life skills. By profession, I teach web development and programming, focusing on helping beginners master full-stack development using modern frameworks like Vue.js, Express.js, Svelte, and Python. I enjoy breaking down complex topics like OOP, machine learning, IoT, and data security into simple, practical lessons. Currently, I’m also working on various side projects, such as building web apps with Laravel, creating game prototypes with Python Arcade, and developing smart plant monitoring systems using ESP32 and C++. I like experimenting with different tools — from Firebase for notifications to PM2 for Node.js deployment — and I always look for ways to share what I learn. Outside of tech, I enjoy physical activities like badminton and fishing, and I find balance by gardening — growing chilies and flowers at home. I love cooking simple dishes like sambal with fried tempeh and anchovies. I believe in living within my means and saving consistently, as I have personal goals like upgrading my gear and planning for my future family. In the long term, I aim to be a supportive parent who encourages my children to pursue their passions, whatever they may be. I’m always ready to work hard, learn, and adapt — whether that’s teaching, coding, or simply enjoying a good game of badminton.
