- 📖Knowledge Base
  Plain-English explanations of the technologies and methodologies used to build your software — no jargon, no fluff.
  /en/knowledge/
  (21)
  - 🛡️Acceptance Testing — Knowledge Base
    Acceptance testing means the computer automatically checks that your software matches the Gherkin scenarios you approved. Every feature has a test that proves it does what you asked for — not what someone thought you asked for.
    /en/knowledge/acceptance-testing/
  - 🤝Afspraak is Afspraak — Knowledge Base
    A Dutch saying: 'A promise is a promise.' When I commit to something — a deadline, a feature, a price — I keep my word. No faceless agency where nobody feels responsible. You talk to the person writing the code. If there's a problem, I own it.
    /en/knowledge/afspraak-is-afspraak/
  - 🤖AI-Assisted Development (Agentic Programming) — Knowledge Base
    I use AI tools (like OpenCode, Claude Code, GitHub Copilot) as an accelerator. Think of it as having a senior engineer who types at 10x speed. The AI handles boilerplate, generates tests, and catches patterns — but I review every line, make every architectural decision, and take full responsibility.
    /en/knowledge/agentic-programming/
  - ⚙️Ansible — Knowledge Base
    Ansible is a tool that automates server setup. Instead of logging into a server and running commands by hand, I write a recipe that describes exactly how the server should be configured. Run the recipe, and the server becomes that configuration — every time, identically.
    /en/knowledge/ansible/
  - ⚡CI/CD Pipeline — Knowledge Base
    CI/CD (Continuous Integration / Continuous Deployment) is an automated assembly line for your code. When I push code to GitHub, a series of checks runs automatically: tests pass, code style is clean, security is scanned, and if everything is green, it deploys to your server — all without manual steps.
    /en/knowledge/ci-cd/
  - ✅Definition of Done — Knowledge Base
    Definition of Done is a checklist that must be satisfied before a task is considered finished. Not just 'it works on my machine' but: code is written, tests pass, reviewed, deployed to staging, approved by you, and deployed to production.
    /en/knowledge/definition-of-done/
  - 🚢Dokku PaaS — Knowledge Base
    Dokku is a mini Heroku that runs on your own server. It turns your code into a live website with a single command: git push. It handles deployments, scaling, databases, and SSL certificates automatically.
    /en/knowledge/dokku-paas/
  - 📊Domain Report — Knowledge Base
    A monthly report covering your site's performance (load times, Core Web Vitals), usage (traffic, popular pages), SEO ranking (search position for key terms), and recommendations (what to improve next month). Included with the monthly hosting subscription.
    /en/knowledge/domain-report/
  - ✉️Email Infrastructure — Knowledge Base
    Reliable email sending and receiving — transactional emails (password resets, order confirmations, contact form submissions) and inbound email processing. I set up SPF, DKIM, and DMARC records so your emails actually land in inboxes, not spam folders.
    /en/knowledge/email-infrastructure/
  - 💰Fixed Price vs Monthly Subscription — Knowledge Base
    Two ways to work together. Fixed price: we agree on scope and price upfront. You pay once, you own everything. Monthly: lower upfront cost, ongoing hosting + monitoring + maintenance + domain reports included. Ideal for startups who need to spread costs.
    /en/knowledge/fixed-price-vs-monthly/
  - 📝Gherkin — Knowledge Base
    Gherkin is a way to write down what your software should do using simple sentences: Given [some starting state], When [something happens], Then [this should happen]. Think of it as a recipe that both you and the computer can read.
    /en/knowledge/gherkin/
  - 🌐Hetzner & Leaseweb — Knowledge Base
    Hetzner and Leaseweb are European hosting providers. They rent physical servers (or virtual ones) that your application runs on. Think of them as the engine room — the physical machines that make your website available to the world.
    /en/knowledge/hetzner-leaseweb/
  - 📋Infrastructure as Code (IaC) — Knowledge Base
    Infrastructure as Code means your servers, databases, and network are defined in files — just like your application code. Instead of clicking around a control panel to set things up, everything is written down in a recipe that can be run automatically.
    /en/knowledge/infrastructure-as-code/
  - 🛡️Monit Monitoring — Knowledge Base
    Monit is a lightweight monitoring tool that watches your server and applications. If a process crashes, Monit restarts it. If CPU or memory spikes, Monit alerts me. It's like a building superintendent who lives on-site — always watching, always fixing.
    /en/knowledge/monit-monitoring/
  - 🎯MoSCoW Prioritization — Knowledge Base
    MoSCoW is a method to decide which features matter most. Every feature gets a label: Must have (essential), Should have (important but not critical), Could have (nice to have), or Won't have (explicitly out of scope for now).
    /en/knowledge/moscow-prioritization/
  - 🚀Ruby on Rails 8 — Knowledge Base
    Rails is a framework for building web applications. Think of it as a pre-built foundation with all the plumbing already in place — databases, user authentication, email, background jobs — so I can focus on building your actual features instead of reinventing the wheel.
    /en/knowledge/rails-8/
  - ⚡Static Site Generator (11ty, Middleman) — Knowledge Base
    A static site generator turns templates and content into plain HTML files — no database, no server-side processing. 11ty is the modern standard; Middleman is its Ruby predecessor. Your marketing site becomes a folder of HTML files that can be served from anywhere.
    /en/knowledge/static-site-generator/
  - 🔄Test-Driven Development (TDD) — Knowledge Base
    TDD means writing the test before writing the code. First, I write a test that says what the code should do. I run it — it fails (because the code doesn't exist yet). Then I write just enough code to make it pass. Then I improve the code while keeping the test green. Red. Green. Refactor.
    /en/knowledge/test-driven-development/
  - 🛡️UFW Firewall — Knowledge Base
    UFW (Uncomplicated Firewall) is a simple firewall for Linux. It blocks all incoming traffic by default, then only opens specific doors for the services that need them — web traffic (port 80/443), SSH (port 22), and nothing else.
    /en/knowledge/ufw-firewall/
  - 🔓Vendor Lock-In — Knowledge Base
    Vendor lock-in happens when your application depends on a specific company's proprietary tools or platform, making it expensive or impossible to switch later. I build with open-source tools on your infrastructure — you can take the code anywhere.
    /en/knowledge/vendor-lock-in/
  - 🔐VPN (WireGuard) — Knowledge Base
    A VPN creates a secure tunnel between your computer and the server. WireGuard is a modern, fast VPN that lets authorized people access private services (like staging sites or admin panels) as if they were on the same local network.
