Employers, clients, and colleagues expect far more from developers than working code. They want solutions that cause no harm, can be verified, are released in small increments, are based on honest estimates, and are built by people who respect each other’s professionalism and never stop improving. These ten principles — drawn directly from Bob Martin’s books and complemented by my own experience across […]

What this article covers: The specific challenges of test automation for AI healthcare applications, including HIPAA-compliant test environments, testing audio processing and AI-generated output, BDD implementation for regulated products, and CI/CD pipelines for health apps. Includes a real case from building a QA framework for Mentalyc, an AI-powered therapy documentation platform. What is test automation for AI […]

The four-ears model (Vier-Ohren-Modell) is an interpersonal communication framework developed by German psychologist Friedemann Schulz von Thun, which assumes that every message can be received on four distinct levels: factual, relationship, appeal, and self-revelation. When the sender and receiver focus on different layers of the same message, misunderstanding occurs and that is the root cause of a vast number of […]

Healthcare software in Germany, Austria, and Switzerland operates under a completely different set of rules than anywhere else in Europe. The regulatory stack is deeper, the compliance timelines are longer, and a developer who treats a healthcare project like a standard SaaS build will fail, not because they can’t code, but because they don’t understand what they’re actually building. This article […]

Every few months, a CTO somewhere reads an article about Netflix or Amazon and decides it’s time to break apart the monolith. Six months later, the team is exhausted, the delivery is stalled and the microservices architecture is somehow harder to maintain than what they started with. This isn’t a story about microservices being bad, more about the wrong question […]

Most articles about reviewing AI-generated code start with a checklist. This one starts earlier with the question every checklist skips: should you even be reading this code at all? I know what you’re thinking. But before you answer „obviously” picture a typical Tuesday on a team with high AI adoption. Cursor generates a PR. Then another. Then three more, because someone ran an […]

I’ll be honest with you: I spent way too long convincing myself I wasn’t ready yet. There was always one more service to review, one more practice test to run through. Eventually I stopped waiting and just booked the exam. And I passed. So if you’re reading this in a similar state of „almost ready” – this one’s for you. The AWS Certified Developer […]

The healthcare industry is entering a new phase In 2025, companies developing AI solutions captured 55% of all healthtech sector funding, compared to 37% the year before (Bessemer Venture Partners, State of Health AI 2026). This growth clearly reflects the direction healthcare investment is heading and has a direct impact on how medical products are built. The focal point of […]

The title „At our company it works differently” did not appear by accident. It is one of the first responses I used to hear as a Scrum Master when I joined a new team and asked why something was done in a particular way. On a certain level, this statement is true. Every company has its own specifics, history, constraints, and culture. But over 18 years of […]

The healthcare startup ecosystem in the DACH region (Germany, Austria, Switzerland) is growing rapidly. Digital therapeutics, remote patient monitoring, and AI-driven medical analytics are becoming key components of modern healthcare platforms. However, building a scalable healthcare product is far more complex than developing a typical SaaS solution. HealthTech companies must manage sensitive medical data, integrate with specialized devices, […]
