Crafting experiences
across disciplines.

I'm Geethaka, a developer and designer with 1+ years building products that live at the intersection of code and craft. I thrive in full-stack environments, cloud-native stacks, and the quiet satisfaction of a well-designed label.

My background spans enterprise software, DevOps automation, and freelance brand work. I treat every project as a system, where every decision is deliberate and every detail earns its place.
