Hey People 👋
I just launched my first service here and wanted to introduce myself.
I'm Nikša - a dev and designer based in Munich, currently studying at TUM. I build landing pages and web apps that look sharp and load fast.
What I offer:
- Landing pages delivered in 2 days
- React / Next.js, fully responsive
- SEO optimized out of the box
- Monthly hosting + updates for just €10/month
If you've got a bigger project in mind - a full web app, AI integration, or something custom - I'm very open to that too. Just DM me and we'll figure it out together.
Let's build something 🚀

Welcome to Contra ✨
Are you an Obsidian or PKMS lover? Can you design and code frontend?

I’ve been thinking about something lately.
Does a wide tech stack signal versatility — or lack of focus?
I work across React, Next.js, Vue, Angular, Three.js on the frontend, and Node, NestJS, Python, and .NET on the backend, along with platforms like Shopify and WordPress.
From SaaS dashboards to e-commerce systems and custom web apps, I’ve built across a pretty broad spectrum.
But here’s the real question:
When someone lands on my work, do they see “this person can build anything” — or “this is exactly who I need”?
Because those are very different signals.
Lately, I’ve been refining how I present my projects — not by reducing what I can do, but by making the value clearer:
→ What problem was solved
→ What impact it had
→ Why it mattered for the business
Not just the stack.
Curious how others think about this:
When you evaluate a developer, do you value range — or specialization?
