Career
Haz’s résumé lists a bachelor’s degree in Business Computer Science at Babeș-Bolyai University’s FSEGA faculty from 2017 to 2020. His engineering career includes an Accesa internship in 2020 and a Frontend Software Engineer role there from September 2020 to June 2023. The same résumé lists Frontend Software Engineer at Flutter UK/I from June 2023 onward, describing feature development, testing, migrations, and code review.[4]

Components a developer can change
React Bits organizes text animations, interactive components, backgrounds, and smaller interactions as source a developer can copy or install. It offers JavaScript and TypeScript choices with plain CSS or Tailwind. This matters when a library’s demo is close to a desired effect but its exact timing, appearance, or behavior needs to change: the component code lives in the application rather than remaining hidden behind a fixed design.[2]
Effects over live interface content
Canvas UI extends this work into GPU-rendered effects. Its components can wrap live page content with fluid, glass, particle, or other shader-based treatments. The implementation uses WebGL or WebGPU and, where available, an experimental HTML-in-canvas API to redraw actual interface content. Unsupported browsers retain the ordinary HTML or an overlay fallback. Developers receive the source through a shadcn-compatible registry and can use implementations for React, Vue, Svelte, and other frameworks.[3][5]
A family of creative tools
His GitHub profile also features React Bits Pro, the Vue and Svelte ports of React Bits, and OpenShaders. They extend the same interest across reusable visual effects, application blocks, and shader examples. The public repositories and live demos give developers both a preview of an effect and code to study, which is particularly useful when learning how motion and graphics fit into an ordinary web interface.[1]
