Projects

Full Stack

TypeScript, React 19, Turso, Argon2, Next.JSPortfólio Self-Hosted

My portfolio is a small CMS: the home page and project pages come from an API that I edit through an admin panel. When cold starts on the free API host started showing visitors a dark screen, I moved the frontend from a Vite SPA to Next.js with Incremental Static Regeneration. Visitors now get cached, fully rendered pages even while the API sleeps, at no extra hosting cost.

Turned a free-tier cold start that showed visitors a dark screen into instantly served cached pages, without paying for an always-on server.

Verbum is a Catholic study platform that puts the Bible, the daily liturgy, Laudes, the Catechism and personal notes in one workspace. It is a React app with a Fastify API, PostgreSQL, Redis and a nightly Trigger.dev worker that prepares each day's content. The post covers the decisions behind it: parsing liturgical references, keeping search in Postgres, making the nightly jobs reliable and treating reading history as sensitive data.

Turned three scattered morning habits (a Bible app, a liturgy website and loose notes) into one study workspace that prepares itself every night.

Python, PyQt5, Google Gemini API, MarkdownPyPost — AI Blog Post Generator

A desktop app that generates SEO-optimized blog posts from a subject and a set of keywords, using Google Gemini AI and exporting the result directly to Markdown, HTML, or plain text.

Turned blog post drafting from a blank-page problem into a one-click operation.
