Building practical software from ambitious ideas.
I'm a dev from the Gen Z generation who enjoys turning ambitious ideas into practical software. My work spans AI engineering, full-stack development, and intelligent systems, with a strong interest in open-source software and trustworthy AI. I believe continuous learning, experimentation, and collaboration are the foundations of meaningful innovation.
Click a tag to jump into a compact project card. Public repositories are linked inside each card; private/company work is summarized without exposing source code, credentials, datasets, or confidential implementation details.
Some of my strongest work is in private repositories because it was built for companies, clients or sensitive business workflows. I do not publish confidential source code, credentials, datasets or internal implementation details. Public summaries focus on architecture, product value, stack and responsibilities.
Open to AI engineering, full-stack development, research assistant and applied AI opportunities.
