Services
Markish Tech designs and builds custom websites —company sites, landing pages, product and event sites— with Astro or Next.js. Every site ships with responsive design, technical SEO, structured data and WCAG 2.2 AA accessibility, and is measured with Lighthouse before it goes live.

Client project
Case study of the official FORJA Challenge 2027 website, a functional fitness competition. A narrative landing page built with Next.js and scroll-driven animation.
A template ships generic design and code meant for many cases, so it usually loads more than needed and is hard to adapt. A custom site is built for your pages and content: it loads only what it uses, respects your brand and can be extended without fighting someone else's code.
It depends on the project. For mostly content sites (company sites, landing pages, event sites) Astro delivers static HTML with very little JavaScript, which helps speed and SEO. When the site needs heavy interaction, user sessions or server logic, Next.js is usually the better choice. This site is built with Astro and FORJA Challenge with Next.js.
