Selected work

Two client sites and a class project. Each one answers the same questions: what was the problem, what I built, and what came of it.

    Built
    • A statically generated Next.js (App Router) site in three languages
    • Availability check and booking request, with input validated by Zod schemas on the server

Code & docs

Code & docs

How I keep a project in order

  1. A checklist before go-live

    Vityilló has a go/no-go table of the legal, GDPR, security, accessibility and indexing tasks that block launch, each with an owner.

    docs/launch-checklist.md (opens in a new tab)

  2. Tests beside the code

    The API guard and the cookie consent each have their own Vitest file next to the module: 28 unit tests between them.

    lib/api-guard.test.ts (opens in a new tab)

  3. The database in the repo

    The class knowledge base keeps its schema and seed data as SQL files, with an .env.example that lists the settings it needs.

    schema.sql (opens in a new tab)
