Jörg Lauenroth

Hey there! 👋
My name is Jörg.

I'm a freelancing full-stack web developer based in Berlin, Germany.

Currently, my main job position is front-end tech lead at Worldia, a platform for tailor-made travelling. But I'm always involved in plenty of other projects as well.

You can check out some of these projects further below and find out more about me on my about page.

Förderverein GARP

As a member of the Förderverein (friends of the school club) at Grundschule am Rüdesheimer Platz, I am responsible for the development and maintenance of their website.

Visitors can register to become a member, get information about the work of the Förderverein and financed projects.

When it's time for the flea market, people can book a spot on the schoolyard over the website. You can also checkout the app I built for check-in and statistics for the flea market.

  • CraftCMS
  • CSS / HTML
  • Design

Flea Market App

For the yearly flea market, organized by the Förderverein GARP, I developed an app to help implementing the hygiene protocol:

People who registered a spot at the schoolyard via the website, got a confirmation email including a QR-Code. This code can be scanned by the app and the current status of the reservation is shown: registered, checked-in or payed.

The app was connected via API to the CMS of the website, so that it was possible to use the app simultaneously by several people while having the data in sync.

At the same time, it was possible to use the app without a connection to the CMS - in order not to be blocked in case of any CMS issues. All data is stored in local storage of the device.

Perackis Architekten

I had the pleasure to implement the website for one of the finest architects in Berlin: Perackis Architekten.

They needed a portfolio to showcase a subset of their work.

This was the first freelancing project using CraftCMS which is always a pleasure to work with.

  • CraftCMS
  • CSS / HTML

Social network

I designed and implemented a simple social network for the movement Aufbruch, jetzt!. They needed a platform for discussions with a very special invitation system.

This was an opportunity to give redwood.js a try. It was quite fun to implement and was my first real project with GraphQL.

For the football world cup in 2014, I've implemented an app for our office at the EEAS where all colleagues were able to bet on the results of each match.

The initial version is currently broken but I am trying to migrate it to the latest Meteor version using React (used to be with Blaze) and styled components.
