Marcel Jelisić from Hannover

I build what your business needs tomorrow.

I make websites, AI assistants for WhatsApp and small automations for businesses that don't have time for tech. You tell me what's bugging you, and I build the fix.

Services

What I can
build for you.

You deal with exactly one person. I look at how your business really runs and build the tech to fit it.

Websites2–4 weeks

A site that makes customers ask who built it.

It loads fast, looks good on a phone and has animations that actually show something. I set up the legal pages, the privacy policy and your Google profile too, so people can find you.

AI agentsaround the clock

A colleague who answers enquiries at 3 am.

On WhatsApp, Telegram or your website. It knows your prices, asks for whatever is missing and sends you a finished enquiry at the end.

Motion & VideoReels, ads, brand

Moving images that stick within three seconds.

Short videos, animations and product clips for Instagram, TikTok and your website. I edit, add sound and then check what actually brings reach.

Then tell me about it. Whatever slows you down every day can often be solved with surprisingly little tech.

Questions

What you want to know.

How much does it cost?

Every project is different. Within 48 hours of our conversation, you’ll receive a quote with each item listed separately. The conversation is free.

How long does it take?

Usually 1 to 4 weeks. You’ll see the progress every week.

Will the website belong to me?

Yes, the content and domain are in your name.

What about data protection?

I build with GDPR compliance in mind: servers in the EU, no unnecessary cookies, and if an assistant processes customer data, you’ll receive a data processing agreement.

Do I need technical knowledge?

No. I set everything up and show you how it works. I stay available afterwards.

Which languages?

German, Croatian and English, for your website and your assistant.
