About

When I was 16, the choice I made to learn about computing brought me into the amazing IT world. With over 5 years of experience, mainly in Python, and additional skills in C++ and JavaScript, I’ve been involved in projects ranging from applied research in artificial intelligence to competitive programming and web development. Driven to apply my technical knowledge in real-world scenarios, I participated in the Build On, ASEAN Hackathon 2021 by Amazon Web Services, where my team and I created a prototype website proposing an improved business model for Carousell. This project taught me a lot about applying technical skills in a business context to create impactful solutions. Feel free to reach out to me at [email protected] if you’re looking for a developer committed to solving real-world challenges through technical expertise.
