Web Applications &Built to Last
I'm David Mattiasson. I build complex web applications for companies that need things done properly. You talk directly to the person writing the code.
What I Build
Whether you have a clear spec or just a rough idea, both are fine. Here's what I work on.
Websites
Fast, modern, clean and written in real code, not a page builder. Anything from a single landing page to a full company site, I build them properly and to last.
Applications
Custom dashboards, internal tools, business portals. The kind of builds that actually require thought. I'm at my best when the problem is genuinely difficult.
Web3
Does your project touch blockchain like smart contracts, dApps, or crypto infrastructure? I've built advanced marketplaces and games in that space too.
Why Work With Me
20 Years of Code
I've been writing code since before most coding tools existed. 13 years as an IT professional and with a university degree. I think about how systems break, not just how they're built.
Modern Stack
React, Next.js, TypeScript, HTML, CSS, Tailwind, Material UI, Node, Python, etc. I work with top-notch AI tooling daily, which speeds things up without skipping the thinking.
Direct - No Fluff
You work with me, not a project manager relaying messages. If something in your brief doesn't make sense, I'll say so. If a better approach exists, I'll tell you. You can count on me to deliver the best solution!
Have a project in mind?
Whether you have a clear scope or just a rough idea, I'm happy to have a conversation with you. No pitch, no sale talk. Let's build something!
Based in Kungsbacka (south of Gothenburg), working with clients worldwide. Project-based, hourly, or whatever fits your situation.
