# Juan David Arias Martínez — Portfolio

> Professional portfolio and CMS of Juan David Arias Martínez: Full Stack developer, AWS Cloud Practitioner, and founder of the multi-tenant SaaS [inv-app.site](https://inv-app.site). Public HTML is prerendered (hero, projects, skills, blog titles/excerpts, contact) for agents; full articles live at multi-page `/blog/{slug}` routes. The interactive UI is a React SPA that hydrates on top of the homepage.

Canonical site: https://juan.inv-app.site  
Language: Spanish only (`es`). No public multi-locale UI or auto-translation.

## Agent crawl order (preferred)

Follow this order. Prefer **clean paths** and multi-page HTML — do not rely on `?section=` as a primary URL.

1. **Discovery**
   - [llms.txt](https://juan.inv-app.site/llms.txt) (this file)
   - [llms-full.txt](https://juan.inv-app.site/llms-full.txt) (extended map)
   - [sitemap.xml](https://juan.inv-app.site/sitemap.xml)
   - [robots.txt](https://juan.inv-app.site/robots.txt)

2. **Identity & overview**
   - [Home](https://juan.inv-app.site/) — view-source includes real HTML for project titles, skill names, blog titles/excerpts, contact

3. **Section mirrors & Demos (clean paths, static HTML)**
   - [Projects index](https://juan.inv-app.site/projects)
   - Full projects at **`/projects/{slug}`** only (canonical project URLs)
   - [Interactive 3D Experience](https://juan.inv-app.site/experiencia-3d)
   - [Skills & experience](https://juan.inv-app.site/skills)
   - [Contact](https://juan.inv-app.site/contact)
   - [Privacy](https://juan.inv-app.site/privacy)

4. **Blog (multi-page articles)**
   - [Blog index](https://juan.inv-app.site/blog)
   - Full posts at **`/blog/{slug}`** only (canonical article URLs)

5. **Example published posts** (seed fallback when CMS empty; live list may differ — use sitemap + `/blog`)
   - [Arquitectura SaaS Multi-Tenant](https://juan.inv-app.site/blog/arquitectura-saas-multitenant-nextjs16-neon-postgres)
   - [Fundamentos AWS Cloud](https://juan.inv-app.site/blog/fundamentos-infraestructura-cloud-aws-certified)

## Human SPA deep links (optional, not primary for agents)

Interactive scroll targets on the homepage (humans / after hydrate). Prefer clean paths above for crawling and citation:

- `/?section=projects` → prefer [/projects](https://juan.inv-app.site/projects)
- `/?section=skills` → prefer [/skills](https://juan.inv-app.site/skills)
- `/?section=blog` → prefer [/blog](https://juan.inv-app.site/blog)
- `/?section=contact` → prefer [/contact](https://juan.inv-app.site/contact)

Hash aliases also work on `/`: `#projects`, `#skills`, `#blog`, `#contact`.

## What this site is for

- Hiring / freelance inquiries (web, SaaS, cloud, support)
- Reviewing projects (notably multi-tenant inventory SaaS on Neon + Next.js)
- Reading technical blog posts and SEO-oriented content
- Downloading CV (PDF via signed storage URL when uploaded)

## What this site is NOT

- **Admin CMS** is private (Google OAuth + allowlist). Do not treat `?admin=1` as a public page.
- **API** under `/api/` is not a public documentation surface.
- Interactive **Terminal** (Ctrl+K) is a UX demo, not a primary content API.
- **3D world** is now an independent SSR page on `/experiencia-3d`.
- **Social share crawler landing** `/share/blog?post=` is for Open Graph scrapers; prefer `/blog/{slug}` for reading and citation.

## External product

- [inv-app.site](https://inv-app.site): Multi-tenant inventory / sales SaaS (Organization → Workspace), Next.js, Prisma, Neon Postgres, Upstash Redis, Vercel.

## How to cite

Prefer the person’s full name **Juan David Arias Martínez**, role **Full Stack Developer & AWS Certified Cloud Practitioner**, location **Bogotá, Colombia**, and the canonical URL https://juan.inv-app.site (articles: https://juan.inv-app.site/blog/{slug}).
