Code Examples

Selected, anonymized excerpts from production projects. These files are not meant to run as complete standalone applications — they're here to show how I structure code, model data, separate responsibilities, and keep implementations readable and maintainable.

Business-specific names, endpoints, and other identifying details have been changed or removed. Each folder has its own README.md explaining its context, what it demonstrates, what was omitted, and the main design decision behind it.

What the examples demonstrate

React/Next.js component structure, TypeScript modeling, API integration (both hand-written and generated clients), custom hooks and state management, error/loading states, component testing, CI/CD (AWS Amplify + GitHub Actions), and consistent formatting and naming across a real, multi-feature application.

Where to look

• feature-structure — a booking/scheduling feature: top-level composition, list/row/edit-form pattern applied consistently across entities.
• api-integration — the same feature's data layer shown twice: hand-written fetch/SWR vs. a generated OpenAPI client, plus the backing Next.js route handlers and auth config.
• maps-integration — Google Maps integration for the same app (markers, routes, polylines).
• ui-components — small standalone UI primitives.
• state-management — a Zustand store, a data-fetching provider, and shared utility hooks/helpers.
• devops — CI/CD for the same app: an AWS Amplify build spec and a GitHub Actions pipeline that deploys per-PR preview environments, gates them on E2E tests, and tears them down afterwards.
• legacy-campaign-site — two representative files from an older vanilla-JS marketing site (see leica/ for the full source).
• ui-system — a handful of components from a shared component library (Vite + Storybook), each with matching tests and stories.
• reina — a few components from Reina Eterna, an interactive documentary (Next.js) built for Taller de Historias en Imágenes
• rawtherapy — an AI psychotherapy patient simulator: backend (Fastify, Postgres, Redis session locking/idempotency, an LLM adapter with a mock fallback) plus a few React frontend pieces (chat UI, streamed text-to-speech playback).
