Crafting digital
experiences.

I'm a passionate Full-Stack Developer who loves building products that are both technically solid and delightful to use. With 5+ years of experience, I've worked across startups and enterprise projects across Southeast Asia.

My approach combines deep technical expertise with a strong sense of design and user empathy. I believe great software is invisible — it just works, beautifully.
