A software engineer. Canonical page: https://www.suboth.com - **ATI Batticaloa / SLIATE** — A Sri Lankan government technical education institute. His **client**, not his employer. He built their website (atibatti.edu.lk). - **Chill Hutz** — A boutique garden resort and restaurant in Batticaloa. His **client**. He built chillhutz.lk. - **BBDSP Consultant** — An IT consulting firm in Batticaloa.
