Outside work he builds [Proxima Analytics](https://proxima.so/), open source analytics that respects privacy. His talks usually start with something he built or an experience he had. ### long bio 131 words · 766 characters Theodore Vorillas is a lead software engineer at [Workable](https://www.workable.com/) in Athens, Greece. Outside work he builds [Proxima Analytics](https://proxima.so/), open source analytics that respects privacy. [Devicons](https://github.com/vorillaz/devicons), an icon font he made for developers, has passed three million downloads. His newer side projects are [jiki](https://jiki.sh/), a Node.js runtime that runs in the browser, and [tok0](https://tok0.dev/), a CLI that trims shell output before an LLM reads it. He likes the web best when it leaves the screen. He has built a braille display out of solenoids and driven it from JavaScript, and he 3D-printed a robotic arm. Most of his talks come back to accessibility, and lately to AI inside user interfaces. He has been on stage since 2018, at JSConf US, NodeConf EU, React Advanced London, JSNation and JSHeroes, in English and Greek. ### topics AI inside user interfaces, and inside tests. JavaScript runtimes, React and the platform underneath. Design systems meeting legacy UI. Accessibility, with hardware when it helps. And the long road from junior to senior. ### formats Conference talks, meetups and the odd panel. In English or Greek, on stage or online. ### booking [x ↗](https://x.com/vorillaz) [github ↗](https://github.com/vorillaz) [linkedin ↗](https://www.linkedin.com/in/vorillaz)
