my blog. for you.

Let’s talk digital.

I’m an independent IT consultant and entrepreneur in the Internet and software business. I’m interested in design, enterprise applications, web apps and SaaS products. I design and develop business solutions and applications. I help companies in terms of software quality and knowledge transfer, e.g. with Angular and Spring Boot.

I see numbers

Metaphors play a vital role in how human beings make sense of the world. The ways in which we view and describe both the world around us and abstract thoughts often are inherently metaphorical. When relating to time, for example, we often use spatial metaphors such as "to look forward to", "time moving forward", or "to turn back time". For some though, relating to time in terms of spatial concepts and relations can take on quite a literal meaning. I've always visualised numbers, ... Read more

Welcome Back: beyond tellerrand Opening Titles Düsseldorf 2021

Last week, I was at the 2021 Düsseldorf edition of beyond tellerrand. As most on-site events during the last two years, beyond tellerrand had been postponed until, earlier this year, they got the go-ahead that the event was finally allowed to take place again. In spite of the rather short time to prepare, Marc and his team once again put on a fantastic event. These beautiful opening titles celebrate the event's return to the limelight with the simple, but very appropriate, words "Welcome ... Read more

The Layers Of The Web – Jeremy Keith @ beyond tellerrand Berlin 2019

Earlier this week - after a hiatus of almost two years on account of having been postponed due to the pandemic - this year's beyond tellerrand conference, an event about design, creativity, and the web, went ahead again. Even though Marc Thiele, the mastermind, organiser, and genuinely awesome person behind beyond tellerrand, ran a terrific series of online events under the Stay Curious moniker while on-site events weren't allowed to take place, it was amazing to be back at this wonderful event ...

User Experience Design Methods & Deliverables

As I previously wrote about, design and user experience (UX) design are disciplines defined and governed by rules, principles, and constraints. The highly recommended Laws of UX provides an in-depth overview of principles and best practices in UX design. Coming from a slightly more hands-on perspective, designer Fabricio Teixeira compiled a comprehensive list of UX design methods & deliverables such as service blueprints, personas, or user journeys.

A Collection of for a Improving the UX of Signup  and  Login Workflows

Independent UX designer Erik D. Kennedy recently published an article with 15 Tips for Better Signup / Login UX on Learn UI Design - a website through which he provides acclaimed courses on both UI and UX design. The article lists general suggestions such as autofocusing on the first field (i.e. the username, or rather: email, field), immediately validating form values, or making input labels clickable, as well as more specific - but no less expedient - ones like making password requirements explicit to ...

Opinion-driven Design: Simplicity Over Flexibility

Software developer Brent Roose recently wrote a blog post on what he calls "opinion-driven design". His point his that while a mindset of "high configurability and flexibility" is undoubtedly common when it comes to the development of software frameworks and libraries, it ultimately is also misguided in most cases. In an attempt to both accommodate every possible use case and to remain in control (also known as the "Not invented here" (NIH) syndrome), framework developers tend to favour flexibility at the expense of ...

Second-order Affordances: Design & Quantum Superposition

A few years ago, having read a thought-provoking article by Csongor Bartus I wrote about design & quantum superposition. The main idea behind this article, and my interpretation, is that - similar to a particle, which exists in a state of quantum superposition - a design doesn't exist by itself but can only ever be realised in a given context and at a specific moment through observation by a user and possibly a device that design is observed with. The gist, ... Read more

Cloud Design Patterns

In the past few months, I've been working a lot with distributed applications and more complex cloud architectures, both in terms of Stratospheric - From Zero to Production with Spring Boot and AWS (the eBook I'm currently writing together with Tom Hombergs and Philip Riecks) and client work. Microsoft's library of Cloud Design Patterns (as previously mentioned in this blog post) is a collection of cloud-related software and infrastructure design patterns that can help you with weighing up the merits of common ...

(Deutsch) Lösung für die COVID-19 Pandemie: Schnelltests als Zugangsberechtigung

Sorry, this entry is only available in German.Contrary to my usual writing habits the remainder of this post will be in German. The reason for this is that although the subject most certainly is of interest to everyone the specifics of the solution outlined in the following mostly apply to the current COVID-19 situation in Germany and my personal experience with that situation. The article therefore is mostly relevant to a German audience. If you're interested in discussing the potential for ... Read more

Five Articles on Software Quality and Design Patterns

This week I'd like to point you to five articles I previously posted on this blog and from which I think that they're as relevant as they were at the time. The first three are about general software design principles, software architecture and software quality while the final two refer to specific best practices and common design patterns for Angular: Writing Disposable Code, Not Reusable Code (November 06, 2016) What Causes Over-engineering and How Can You Prevent It? (April 16, 2017) Less Is More ... Read more
