Websites & web applications from Frankfurt

You take care of your business. I take care of the digital side.

I build websites, interactive maps and custom applications, and look after them after launch if you want. Personal, straightforward and all from one person.

What I can build for you.

Three areas, separately or together. What gets built depends on your plans, not on a package.

Websites & digital presence

You get a website that shows your business clearly and professionally: designed for you, fast to load and as easy to read on a phone as on a computer. Visitors see straight away what you offer and how to reach you.

Depending on the project

  • Company website
  • Landing page
  • Contact and enquiry forms
  • Digital information pages
  • Mobile optimisation
  • Technical search engine optimisation
  • Ongoing updates

Interactive maps & applications

When an ordinary website is not enough, I build an application for your purpose: a map where visitors find your programme, an overview they can filter, or an interface where you maintain your data. In the browser or as an app.

Depending on the project

  • Event and festival maps
  • Digital programme overviews
  • Custom web applications
  • Data-driven platforms
  • Mobile applications
  • Interfaces and admin tools

Hosting & technical support

If you want, I stay responsible after launch: your solution runs on a server in the EU, I keep it up to date, fix errors and make changes. You have one contact who knows your project.

As agreed

  • Hosting
  • Maintenance and updates
  • Technical troubleshooting
  • Upkeep and adjustments
  • Further development

Ideas that already became real.

Real projects with real screens: a festival map, two websites with their own signature and my own platform. Each one has its own page with the starting point and what was built.

Open Viertel

The programme of the Bahnhofsviertelnacht as a map instead of a PDF: 97 points at 63 places, filtered by four categories. Behind it a back office where every entry is maintained once and is correct everywhere straight away. No extra work for the organisers.

Tragwerk

The website of a Frankfurt agency for subculture, nightlife and urban space, designed in the style of its own project plan: scratched paper, capitals, a flickering wordmark. Plus a second world at night for the partner platform Frankfurter Straßen.

One person to talk to. From day one.

I am Philipp Alt, founder of nomie.systems.

I build digital solutions for people and businesses who have a good idea but would rather not deal with the technical side themselves.

For eleven years I worked in sales for Red Bull, calling on clubs, bars and festivals, most recently as Area Manager. So I know how little time a business has for technology. Today I build myself: projects for clients and my own platform unowli, which is also in the App Store.

What matters to me: understanding what you really need, building a solution that fits, and staying reachable after launch.

You talk directly to the person who builds your project.

Talk it through. Build it right.

  1. Tell me about your idea.

    We clarify what you have in mind and what it needs to do.

  2. I work out a solution that fits.

    You get a concrete proposal and, once agreed, the technical build.

  3. If you want, I keep looking after it.

    Hosting, maintenance and further development can be agreed individually.

Planning something? Let’s talk.

A new website, an interactive application or a custom digital solution: tell me briefly what you have in mind.

Available Monday to Friday, 9 am to 6 pm (Frankfurt time).
