It would be my pleasure to discuss your project over a coffee, with no obligations.


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. Code:

HTML 5 CSS 3 JavaScript Liquid Eleventy

Frontend Enhancement

After doing a ClimateHack project together in February 2021, I supported the Cologne based startup Planted by enhancing a webflow project and integrating payment providers.

Webflow JavaScript HTML CSS

Meetup Management

In early 2020, I assumed management responsibility for the Cologne web performance meetup. We held a series of international lectures by Patrick Meenan, Andrew Petryk, Anna Backs und Christina Zenzes, amongst others, to inspire an audience extending beyond the borders of the region.

Plugin for WordPress

This WordPress plugin to assist our customers' editors automatically purges the cache memory at wao.io's performance optimization servers. The plugin was released on WordPress.org in 2020.

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.

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, and CSS frameworks 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 the WordPress CMS. Both plugins were included in the official directories after being successfully tested. 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, 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.

Talks and Events

At conferences, courses, and meetups I like to exchange ideas on a professional and personal level.
