Michael Seliger – Insights https://michaelseliger.com/en/insights Articles on software architecture, cloud, e-commerce and team leadership in mid-sized companies — assessments from real projects, about once a month. en Expo over native — lessons learned from a cross-platform app https://michaelseliger.com/en/insights/2026-03-expo-statt-native-lessons-learned https://michaelseliger.com/en/insights/2026-03-expo-statt-native-lessons-learned For most apps, Expo is enough — faster, cheaper, one codebase. And it brings infrastructure you would otherwise have to build yourself. Where it delivered, where it hurt, and when it has to be native after all. Architecture Wed, 11 Mar 2026 00:00:00 GMT Astro over Next.js — the frontend decision that mostly never gets made https://michaelseliger.com/en/insights/2026-02-astro-vs-nextjs-marketing-sites https://michaelseliger.com/en/insights/2026-02-astro-vs-nextjs-marketing-sites When picking a frontend, teams often only weigh the "big" ones — Next, Nuxt and the like. For websites, landing and marketing pages, Astro is frequently the better choice on maintenance, performance and bloat. An assessment — using this site as the example. Architecture Wed, 11 Feb 2026 00:00:00 GMT The mid-market stack, part 3: serverless in house — functions without Cloudflare https://michaelseliger.com/en/insights/2026-01-mittelstand-stack-serverless-dokploy https://michaelseliger.com/en/insights/2026-01-mittelstand-stack-serverless-dokploy Cloudflare Workers are technically excellent — and still put some companies off. How to get functions behind a URL just as easily, without leaving your own stack. The finale of the mid-market stack series. Architecture Wed, 14 Jan 2026 00:00:00 GMT The mid-market stack, part 2: Terraform for small teams — when it starts to pay off https://michaelseliger.com/en/insights/2025-12-mittelstand-stack-terraform-kleine-teams https://michaelseliger.com/en/insights/2025-12-mittelstand-stack-terraform-kleine-teams Clicking it together is faster — until a few months later nobody knows what is actually running. Why Terraform pays off from the very first person in the IT team, and where it turns into an overhead trap. Part 2 of the mid-market stack series. Cloud Wed, 10 Dec 2025 00:00:00 GMT The mid-market stack, part 1: Hetzner instead of a hyperscaler — when it is enough, when it is not https://michaelseliger.com/en/insights/2025-11-mittelstand-stack-hetzner-statt-hyperscaler https://michaelseliger.com/en/insights/2025-11-mittelstand-stack-hetzner-statt-hyperscaler "Cloud" reflexively means AWS or Google for many mid-sized companies. That is often the most expensive answer to a question nobody asked. Part 1 of a series on a modern, affordable stack without enterprise overhead.

Not a contradiction, but exactly the question every CMS decision is really about. An assessment from fifteen years of selection processes. E-commerce Wed, 08 Oct 2025 00:00:00 GMT What I keep from 15 years in an agency — and what I now do deliberately differently. https://michaelseliger.com/en/insights/2025-09-agentur-learnings https://michaelseliger.com/en/insights/2025-09-agentur-learnings After fifteen years of agency work and team leadership, I drew a line in early 2025 and started out solo. Not a break with the past — more a deliberate inventory: what was genuinely good, what was only habit, and what cost more energy than it was worth. Leadership Wed, 10 Sep 2025 00:00:00 GMT
