Jiří Machynka
I build frontend-first products that are fast, accessible, and dependable. Deep in Vue / Nuxt and React / Next, with TypeScript backends from tRPC to Postgres.

About me
Hey, I'm Jiří, a Frontend Developer based in Ostrava. I ship Vue features for clients, and in the rest of my time I build my own products end to end, from the Postgres schema to the pricing page.
Some of them run on each other: Sonuslab Storage holds the files for PDFmod, SmartzQuiz and Decibel Demon, and Sonuslab's audio API powers Decibel Demon's clips and voices. Vue and Nuxt come first; React and Svelte when a project calls for them.
