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.

HTML CSS Fractal Handlebars Webpack

Optimization and Enhancement

For the Sustainable Development Goals (SDG) consultants of Wandelpunkt-Consulting.de I added new content and optimized the blog's loading time. Wandelpunkt-Consulting.de

WordPress Semplice CSS SVG

Frontend Enhancement

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

Webflow JavaScript HTML CSS

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

Shopware 6 Symfony PHP Vue.js

React Web App

wao.io's graphical user interface visualizes technical data and allows webmasters to configure how their websites are optimized. I developed and updated app components as a member of the front-end and support team. wao.io/de/about-us/experts/ingo-steinke

React JSX ES6 CSS-in-JS Storybook

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. www.meetup.com/cologne-germany-high-performance-website-optimization-group

Event management Web performance

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.

Cleaner Web label

Carbon-aware website statement

This website at https://www.ingo-steinke.com/ holds the °Cleaner Web label for climate conscious websites.

Cleaner Web label

The website meets the °Cleaner Web standard. It has been tested for how climate-conscious the website is using objectively measurable factors.

In order to make a contribution to climate protection digitally as well, we have had this website checked for carbon emission optimization aspects and are in the permanent process of further optimizing it in this regard and always designing future changes according to climate-conscious aspects.

Testing categories of the °Cleaner web standard are:
  • Website content
  • Amount of data
  • Energy usage on user device
  • Green hosting
  • Server and performance
  • Data transfer
Ongoing climate optimization

Furthermore, our goal is to continuously improve the website - we see this online measure as one of many climate protection building blocks to actively contribute to the permanent reduction of CO2 emissions. In the event of major changes or a relaunch, we will have the website reviewed again.
