About

I'm Toby, a developer who builds mobile and web applications from idea to production.

Portrait of Amzath, black and white

I care about doing things properly — clean architecture, clear communication, and products that don't fall apart after launch.

My recent work spans a mobile event-booking platform with multi-provider payments (Explotel), a multi-tenant seller e-commerce platform and storefront (Motiboutik), and a WordPress SEO translation plugin (Dotaga Translate) — see Projects for the full case studies.
