About Martin

I build custom websites and web applications that load fast, rank on Google, and save businesses and independent professionals from technical headaches.
I'm a Computer Engineer and full-stack web developer. I take projects from start to finish: design, development, deployment, and SEO. That means you work with a single person responsible for the whole cycle, no middlemen and no loose ends.
I work with WordPress (custom themes, no page builders), React, TypeScript, Node.js, and Python. I also implement local SEO (Rank Math, Google Analytics 4, Search Console), multilingual sites (Polylang), and solutions on Microsoft 365 / Power Platform, drawing on my IT consulting experience for clients like SQM and Verisure.
I can help you with:

Corporate websites and landing pages that convert
Custom catalogs and online stores
Speed optimization and SEO
Migrations, maintenance, and security for existing sites
Automations and integrations (Power Platform, APIs)

What sets me apart: I deliver every project actually working, with clean code, strong performance, and clear communication at every step. I don't just write code, I think about the business behind the site.
