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.

Reflectoring: Reactive Architecture with Spring Boot

Based on asynchronous event processing, message-driven data streams, and non-blocking I/O reactive programming is a popular paradigm for developing web and cloud applications, particularly large-scale and distributed ones using a microservices architecture. Some time ago, I published a tiny introductory post on reactive programming with Spring Boot and Spring WebFlux. Reflectoring has this much more in-depth article on reactive architecture with Spring Boot, which covers everything from building a traditional synchronous-style application, converting such an application to a reactive architecture, and using and ...

Currying in JavaScript

A reference to logician Haskell Curry, currying is a technique for converting a function that takes multiple arguments into a chain of abstract functions that each take a single argument (see Currying). Besides its significance for studying functions in the context of theoretical computer science and its relevance to lambda calculus both in the context of mathematics and linguistics, currying has very practical applications in functional programming. In a way, it's one possible approach for following the inversion of control design principle and ...

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, ...

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 ...

No-code, Low-code, Some Code and Everything In-between

CTO-for-hire (through Freeman Clarke) Alex Hudson recently wrote an article about what he terms "The 'No Code' Delusion": That so-called no-code and low-code tools will replace bespoke business software development entirely, no trained software developers required anymore. In a nutshell, it's the old pipe dream of just having to write a specification (in this case a visual one) and having the actual code write itself, the fallacy here of course being that the code is the final product rather than the specification ...
