Web and Software Projects
Make up your own mind about my work! A selection of my past projects:
Portfolio Relaunch
My relaunched portfolio Ingo-Steinke.com illustrates my work as a web developer. Modern design and typography, cutting-edge technology, and extensive textual revisions characterize my updated professional portfolio. Source Code:

HTML 5 CSS 3 JavaScript Liquid Eleventy
Atomic Design System
As a senior lead developer, of a team of front-end web developers, I developed a modular system for the relaunch of multiple websites of an international corporate customer.
The Fractal framework served as a technical basis.

Plugin for Shopware
My first Shopware 6 project was an administrative plugin facilitates load time optimization for online shops via an API. It has been released in the official Shopware store in 2020. store.shopware.com/waoio62482995391f/wao.io-cache-control.html

React Web App

Meetup Management

Small Business Website
I built Kleiderordnung-Duesseldorf.de as a single page website with tab navigation in 2016. I adapted the graphical print design for flyers and business cards in collaboration with the designer. www.kleiderordnung-duesseldorf.de
HTML 5 CSS 3 JavaScript PHP
Long-Lasting Solutions
I can implement your layouts across platforms, and pixel-perfectly if needed. My goal is to build long-lasting solutions that are elegant, transparent, and easy to maintain. Modular components, themes, as well as CSS frameworks and methodologies like BEM and Atomic Design help to simplify collaboration and further development. Continuous testing allows me to discover and eliminate errors at an early stage.
Full-Stack Experience
When enhancing existing code, I benefit from professional experience and a pragmatic approach. With back-end and DevOps experience and a high willingness to learn, I can also take charge of tasks that may arise besides front-end development.
Plugin Development
My preferred approach is to implement back-end interfaces as independent modules. For the web performance service wao.io, I developed plugins for Shopware 6 and WordPress. Both plugins were included in the official directories after being successfully tested. I am currently working on a WordPress plugin to detect plugin conflicts. I also developed themes for Shopware 5 and 6, for JetBrains-IDEs like PHPStorm and IntelliJ IDEA.

Work and Passion
What still fascinates me
Worldwide communication and inspiration: The World Wide Web connects people with robust and decentralized technology. Websites designed to offer everyone access to this network need to be attractive, fast, and accessible. My work helps to make this dream a reality.
Professional Background
I founded a start-up in 2000 whose first products were interactive websites and browser games. Later, our core business transitioned to search engine optimization and our Active-Webshop software.
While employed as an e-commerce engineer at Xsite in Düsseldorf from 2010 to 2014, I developed online shops for Shop-Apotheke.com, Ars mundi, and other customers. As a technical consultant at Sevenval Technologies (later Avenga Germany) in Cologne and Berlin, I optimized the loading time and mobile phone compatibility of apps and websites for Frankfurter Allgemeine Zeitung and created front-end applications for wao.io and other customers. I have been a freelance web developer since late 2020.
Future Topics and Sustainable Development
In the IT industry, innovation, transformation, and digitalization often mean nothing but technological progress. In many cases, social challenges in ecology, equality, safety, and data protection do not receive the priority they deserve. I want to support ethical and ecological projects, for example the transition in the transport sector, renewable energies, or environmentally friendly fashion. I'm a Fairantworter, a reflecta Changemaker, and I signed the Sustainable Web Manifesto.
In my DEV Blog I regularly publish articles about web development and related technological topics.
Talks and Events
At conferences, courses, and meetups I like to exchange ideas on a professional and personal level.
