About Me

I'm a passionate full-stack software/web developer with sheer obsession for creating unique digital experiences.

My Journey

With over 3 years of experience in web development, I've worked on projects ranging from personal to small-scale business web applications. My journey began with a curiosity about how things work on the web since I was 9, and it has evolved into a passion for crafting digital solutions that make a difference.

In 2024, I also dived into reverse engineering, particularly on iOS. I was so amazed by how elegant iOS internally is, and what are the powerful things you can do with iOS jailbreaking. Even though I somewhat feel I started diving in the jailbreaking community a bit late, I still believe I can still bring innovation to the community. Now, I have successfully released some tweaks / jailbreak application that people might've deemed useful.

In terms of being a programmer in general, I believe in writing clean, maintainable code and staying up-to-date with the latest technologies and best practices as much as I can. When I'm not coding, you may find me learning a new skill, learning new frameworks, or helping other developers.
