Browser-first apps, Plokk, and AI-assisted development.

What this blog covers

These are working notes from building and maintaining a small set of browser-first products. The case studies walk through real engineering decisions - how EdImport turns broker PDF statements into FURS-compliant tax XML entirely in the browser, and how the same privacy-first, local-processing approach keeps sensitive data on the user's own device across the studio's apps.

The development and design articles are practical rather than theoretical: prompt engineering techniques that survive contact with production traffic, patterns for building progressive web apps that feel native, and a detailed guide to designing dark-mode-first interfaces. Each piece is written from first-hand work on shipping software rather than summarized from elsewhere.

New articles are added only when there is something genuinely worth documenting - a problem that was hard to solve, a pattern that paid off, or a decision worth explaining. Accuracy and usefulness matter more here than publishing volume.
