About Yanko

Bulgarian developer, translator, and coordinator based in Yokohama. I like making useful things — from ambient smart‑home tools to tidy, multilingual websites — and helping people communicate across Japanese, English, and Bulgarian.

What I do

  • Software & UX: Cross‑platform apps (C#, Swift, Lua). I enjoy small details: smooth animations, readable typography, and latency‑free interactions.
  • Smart‑home tinkering: Building calm, ambient interfaces for air quality, lighting, and curtains — useful without being shouty.
  • Languages: Translation, proofreading, and coaching for JP↔EN↔BG with a natural, context‑aware tone.
  • Events: Coordination for cultural & sports projects (especially Rhythmic Gymnastics) across Japan and Bulgaria.

Co‑founder, Team OKINA

A playful studio “obsessed with design, technology, and all things Japanese,” crafting edutainment‑rich apps about classical arts. The name Okina nods to the venerable “wise elder” of Noh — tradition infused with modern craft.
