About
Tadeáš Kašpárek
One contact from brief to launch. Nothing gets lost on the way.
Tadeáš Kašpárek, web developer from Otrokovice. I build websites, online stores and web apps for businesses in the Zlín region and across the Czech Republic.
Mayhem Dev is me. I wrote my first page in HTML and CSS in 2021. From December 2022 I worked at HaSaM s.r.o., mostly in support. There was little room for web development there, so I made it my own: after work I taught myself React, Next.js, TailwindCSS and Shopify Liquid at home and built what is now my portfolio on my own projects.
I have been freelance since September 2025. For the agency Pixxi.cz I do the whole front end, such as a Next.js booking system for four mountain lodges or the Husky Outdoor store on a custom Shopify theme. For my own clients I build sites from design to launch. Chata na Soláni takes enquiries for a chosen date right in its opening section.
I care about the things a visitor notices without being able to name them: typography, smooth animation and a page that loads fast on a phone. I write TypeScript, build animation in Framer Motion and GSAP, and draw designs in Figma.
