BeVisionare | Website

https://www.awwwards.com/sites/visionare
A scrolling interactive single-page presentation with gorgeous CSS animations for certain situations/scenarios. I used custom scroll and animation handler/scripts. All animations are created with CSS3 with a fallback to jQuery.

Survey System for Toptal Client

A Node.js, Vue.js, Nuxt.js, and MongoDB-based survey system.
My task was to build the entire survey system. The back-end part was created on top of Nuxt.js to help with the Vue.js front-end server-side rendering. Vue.js with custom-made components powered the front-end. Since the client was using MongoDB, I prepared and implemented additional collections for our needs.

WebRTC Example Project

Because I love to study new things, I decided to create a simple WebRTC video chat app. The front-end was built with simple, pure HTML, CSS, and no-library JavaScript compiled from TypeScript. We don't need to have a server for WebRTC calling, but it is a lot easier to use a server to connect two browsers. The server was built with few lines of JavaScript and runs on Node.js, again without any external library. To notify the server, I used a simple fetch/Ajax request; to notify the user, I used a few SSE (server-sent events).

Adys Music

The presentation page for a Czech music band. This was a solo project. I was in charge of everything from the front to the back end. I designed and coded the entire page. It is written in pure HTML, CSS, and JavaScript, with no libraries used.
