## Projects

- [Portal da Câmara — The Digital Front Door of a City Council](https://zwinglio.com/projects/portal-camara/): The official portal of the Câmara Municipal de Parnamirim (RN, Brazil): news, events, galleries, full legislature management, RG appointment scheduling, a transparency portal with multi-format export, and a SAPL mirror — four-time winner of Brazil's national transparency prize (Selo Diamante).
- [Fast Kanban — A Zero-Signup Kanban for Project Roadmaps](https://zwinglio.com/projects/fast-kanban/): How I removed user accounts from a kanban entirely: boards anyone can read through a link, writes protected by a one-time scrypt-hashed edit key, human-readable card IDs from atomic per-board sequences, and one Hono process that runs on Bun in development and Node in production.
- [Personal Portfolio — The One You're Viewing Right Now](https://zwinglio.com/projects/painel-contratos/): A trilingual Astro portfolio and blog built around one rule: publishing must never become a chore. Why I chose Astro over Nuxt, themed Bootstrap over Tailwind, Markdown over a CMS, and translated UI over translated content.
- [Zudget — Know What You Can Spend Before You Spend It](https://zwinglio.com/projects/zudget/): A personal finance planner that models money the way it really moves: accounts, planned vs. paid entries, credit-card invoices with installments, budgets, goals and recurring entries. A SvelteKit monolith on MySQL, with money in integer cents, tests against a real database, and an SSH-locked deploy.
- [Zweek — A Real-Time Weekly Planner Built to Stay Simple](https://zwinglio.com/projects/zweek/): How I built a weekly planner that syncs phone and desktop instantly without a sync framework: a Vue 3 SPA, a Hono API, a MySQL database moved next to the app after Turso failed in production, and per-user WebSockets — small enough for one person to own end to end.
