astro-split-build: building a large multilingual Astro site on a shared host
An open-source npm package that builds a big Astro site one locale at a time and checks the merged pages.
About me
Websites, stores and web apps for 15+ years. One person, from the first call to support.
I've built everything from front-end interfaces for international e-commerce platforms to web applications and sites written from scratch. My core stack is Laravel on the back end and Astro, Vue and TypeScript on the front, and I own the whole system — architecture, implementation, deployment and support. Every project gets a solution shaped around it, on a current stack.
AI tools are part of how I work: code review, automated tests, content editing, architecture decisions. That isn’t corner-cutting. Automated checks catch problems before they reach production, which leaves me time for the parts that actually move your business. The same approach produced my own headless CMS — pages, translations and media in one panel, with AI wired in over MCP.
The rest is detail work — collaborating with UX designers, implementing SEO, setting up monitoring. Accessibility to WCAG 2.2 AA belongs in that list and is checked automatically on every change rather than quoted as an extra. I keep dependencies current and adopt new technologies early, so your project launches on a stack that won’t be dated in a year.
As for the name: spoko is Polish for “easy, no stress”. That’s how working together should feel.

A unique combination of computer science and visual design — giving me both the technical depth and the creative eye to build products that work and look great.

Technologies and tools from client work and my own projects.
REST APIs, queued jobs, admin panels, automated translations and data pipelines — the back end of every system I own.
Fast, SEO-friendly static and hybrid sites with interactive islands — from marketing pages to headless front-ends and my own larger systems.
Claude Code and Codex agents working in parallel — Herdr to run and watch them, Cezar to take a task from issue to reviewed PR, MCP to reach my tools. I plan and review; agents write.
Automated research, recurring workflows and repetitive tasks — connecting APIs and services to collect, process and move data with less manual work.
Custom online stores and product catalogs — from PrestaShop, Magento and Salesforce Commerce Cloud storefronts to fully headless solutions.
Custom themes, plugins, REST API integrations, and headless WordPress setups.
PHPUnit, Pest and Playwright suites, performance budgets, uptime monitoring, and error tracking. Issues caught before users notice them.
Contrast, keyboard operation, focus order and semantics, checked by axe and Playwright in both themes. Audits and fixes for sites I did not build, too.
Version control, code review, CI/CD pipelines and deployments on Cloudflare Pages and Workers.
App Router, Server Actions and server components for apps that need real state behind a login — deployed on Vercel or Cloudflare Workers.
Search engine and AI engine optimization (llms.txt, structured data, RAG-ready content). GA4, GSC, Core Web Vitals monitoring.
Utility-first CSS frameworks for rapid, responsive design implementation with consistent styling across every device.
Semantic, well-structured markup with clean, maintainable styles and modern layout techniques.
Modern ES6+ on both sides of the network — browser code and Node.js services, scripts and build tooling.
Mobile-first designs that work seamlessly across all devices and screen sizes.
Modern build tools and package managers that streamline development workflows and manage dependencies effectively.
Swagger/OpenAPI for REST APIs, project documentation, and clear technical guides for teams and clients.
Design tools for graphics, prototypes, and layouts. Claude Design and Pencil.dev for rapid AI-assisted design iteration.
The scope is written down before the first line of code and cut into small steps. AI agents write much of the code; every change is read by an agent on another company’s model, and tests and CI are the hard gate – small changes ship on that, large and critical ones I read myself. A deployment can be rolled back in one move; dependency updates, monitoring and documentation are the standard, not an extra. This site goes through the same: on every change, WCAG 2.2 AA accessibility checks in both themes before anything reaches production.
