I build practical web applications, automate repetitive workflows and investigate technical problems. Based in Portugal, available for fully remote employment and freelance projects.
My work combines implementation, reproducible tests, documentation and customer-facing experience. I use AI-assisted development with code review and verification.
| Project | What to review | Evidence and scope |
|---|---|---|
| Astro Commerce Core | TypeScript domain packages: order transitions, pricing, cashflow, SQLite and runtime safeguards | 23 tests passing + TypeScript check. Offline extraction; no live payments or customer data. |
| Book Pipeline | Document production and deterministic content-integrity QA | Documented reference manuscript check: 4,322 / 4,322 fragments verified. |
| Astro Calendar Core | Spanish/Portuguese date rules, timezone conversion and fixed-clock regression tests | 16 tests passing + TypeScript check. Focused library extraction, not the full application. |
The Core repository tests were verified locally on 15 September 2026 with Node.js 24.18.0. Each README explains how to reproduce them and the sample's limitations.
