Experience

A Website for Content Creators

http://www.pickey.cz
Developed a PHP and Vue web application for creators providing space where they can share content with their subscribers in different tiers. On this project, I took care of the front-end part of the application written in Vue with Nuxt.js. My primary responsibility was to deliver a responsive website while consuming all provided REST endpoints.

Portal for Managing Repairs and Service Management

Created an Angular and C# based web application providing tools to manage the whole service process from customer visits in the store to delivering repaired products. For this project, I was a Full-stack developer taking care of implementing the required functionality from correct database structures to UI implementation.

Blog CMS

Developed a Blazor and WebAssembly-based portal for content management. The portal provides mechanisms for publishing different types of content. This project was made completely by myself, from database structures to the Blazor UI.

Building Blazor WebAssembly Applications with gRPC

Wrote a book about web development with Blazor and WebAssembly technology. How to speed up the communication between clients and servers using gRPC instead of REST and how to speed up development with source generators. This and more is covered in my book written in 2022.
