Practical insights and guides on PHP/Symfony, React/Next.js, legacy modernization, and software architecture, drawn from 18+ years of building web applications for European businesses.
A Berlin consultancy invoicing a French client, a German GmbH placing engineers on-site in Amsterdam — these trigger different VAT and permanent-establishment outcomes most founders only discover during a cross-border audit. Here is the practical map.
Read moreCursor, Copilot, and ChatGPT keep suggesting the same handful of npm packages — and five of them are deprecated, supply-chain risks, or production landmines. Here is what we find in real vibe-coded codebases, why each package is dangerous in 2026, and the modern replacements we install during every rescue.
Read moreA real-world migration playbook for large Doctrine 1.x codebases: schema-first entity generation, a dual-ORM bridge that keeps legacy controllers alive, a snapshot-based test harness, and the four-month cutover sequence that retired 700K lines without freezing feature work.

Read moreRAG demos look great — production RAG fails predictably. Here is what goes wrong with chunking and reranking, and the four-question eval harness that catches 80% of regressions before they reach users.
Read moreMost SaaS teams wire up Stripe in a weekend and call it done. The teams hitting 110%+ NRR make a different set of engineering decisions — on proration, upgrade flows, dunning, and metered billing — that compound quietly into millions of ARR.
Read moreMost production LLM agents fail not because the model is wrong, but because the orchestration layer cannot recover when one step times out. This post shows how the Symfony Workflow Component — built for business processes — makes an excellent agent loop runtime with explicit state, replayable transitions, and built-in audit traces.
Read moreMigrating a WordPress site to headless Next.js without tanking your rankings is possible — if you do it incrementally. This is the step-by-step replatforming playbook for mid-size European businesses with hard-earned SEO authority.
Read moreBilling and support data catch cancellation two weeks too late. The signals that actually predict churn live in your product telemetry — feature adoption decay, session depth collapse, and the integration-disconnection pattern that precedes 90% of downgrades.
Read moreWhen Twig has hit its ceiling but a fully decoupled React SPA feels like overkill, Inertia.js gives Symfony teams a third option — modern frontend components without an API layer, a separate deployment, or a complete rewrite.
