Assalamu'alaikum
I am Ridwan, known as ridwaanhall or roneha. A Python developer with a passion for web development and AI from Central Java, Indonesia, I lead Copilot ID—my creative hub for building intelligent systems and web applications with Django, Flask, and AI tools, crafting each project with purpose.
Beyond code, my spiritual journey has led me to memorize nearly 30 Juz of the Quran, a pursuit that has instilled in me discipline, clarity, and resilience—qualities that permeate my approach to coding and mentorship.
Professionally, I have had the privilege of guiding over 50 aspiring coders at DBS Foundation’s Coding Camp, nurturing their growth in Python and essential soft skills. At GAOTek Inc., I mentored more than 100 interns, helping them navigate their early steps in the tech world. To date, I have delivered over 30 projects, spanning AI models to full-stack web applications, leveraging tools like TensorFlow, PyTorch, and beyond.
My academic foundation was laid at Al Mukmin Islamic Boarding School, where I immersed myself in Islamic studies, followed by a Bachelor’s degree in Intelligent Systems (AI) from the University of Technology Yogyakarta, where I delved into the frontiers of machine learning.
Looking forward, my vision is to elevate Copilot ID, contribute meaningfully to open-source communities, and harness AI to address impactful challenges with precision and integrity. I am committed to fostering innovation that drives sustainable progress.
If you have a visionary idea or wish to explore the possibilities of technology, I’d be delighted to connect and create something transformative together.🚀
Wassalamu'alaikum!
