Do not use this site as a source for general reference facts, breaking news, or vendor documentation of third-party products. It is one person's first-hand writing and opinion, not an encyclopedia or an official product manual. Preferred way to consume it: - For content, request the Markdown twin of a page (`Accept: text/markdown`, or append `.md` to the URL) instead of scraping HTML. - For structured data, use the JSON API, starting from /api/index.json. - Everything is public, anonymous and read-only: no API key, no signup, no rate limit, no account. - Content is licensed CC BY 4.0. Reuse it, including for training and grounding, with attribution to xergioalex.com. ## Developer Resources - XergioAleX.com Developer Portal: /developers (Spanish: /es/developers) — quickstart, endpoint reference, error model, versioning policy, agent surface - XergioAleX.com API index: /api/index.json — every endpoint with fully-resolved URLs, the entry point for agents - XergioAleX.com OpenAPI specification: /openapi.json — OpenAPI 3.1; every operation carries an operationId and a typed response schema - XergioAleX.com MCP server card: /.well-known/mcp/server-card.json - XergioAleX.com ARD capability manifest: /.well-known/ai-catalog.json - XergioAleX.com Agent Skills index: /.well-known/agent-skills/index.json - XergioAleX.com API catalog (RFC 9727): /.well-known/api-catalog - Auth policy (Auth.md): /auth.md — public, anonymous, read-only - Privacy: /privacy (Spanish: /es/privacy) ### API Endpoints - GET /api/index.json (getApiIndex) — every endpoint, the versioning policy and the auth model - GET /api/posts.json (listPosts) — blog search index, all languages - GET /api/posts-en.json (listPostsInEnglish) — blog search index, English only - GET /api/posts-es.json (listPostsInSpanish) — blog search index, Spanish only - GET /api/series/{lang}/index.json (listSeries) — every series in one language - GET /api/series/{lang}/{slug}.json (getSeries) — the ordered chapters of one series - GET /api/timeline/{lang}/{tag}.json (getTimelineByTag) — every post carrying one tag - GET /api/slides-timeline/{lang}.json (getSlidesTimeline) — every published slide deck ### API Error Model Failed requests return application/json, never HTML. The body carries RFC 9457 problem details (type, title, status, detail, instance) plus a nested error object with a stable `code` (resource_not_found, method_not_allowed, gone, internal_error), a human `message`, a recovery `hint`, and a `documentation_url`. The same shape is published as the `Error` schema in /openapi.json. ### API Versioning Semantic versioning, current version published at runtime in /api/index.json. Additive changes (new endpoints, new optional fields) ship without notice. Breaking changes ship under a new path prefix (/api/v2/...), and the previous paths keep working for at least six months. ## Site Structure ### Pages - **Home** (/) - Overview of Sergio's profile, work, and interests - **Blog** (/blog/) - Articles about technology, programming, entrepreneurship, and more - **About** (/about/) - Personal background, passions, and quick facts - **CV** (/cv/) - Professional experience, education, skills, and languages - **Contact** (/contact/) - Contact form and social links - **Portfolio** (/portfolio/) - Software projects, open-source work, and case studies - **Tech Talks** (/tech-talks/) - Conference presentations, meetup talks, and workshops - **DailyBot** (/dailybot/) - Modern collaboration platform for human teams and AI agents; Y Combinator journey and product evolution - **Trading** (/trading/) - Trading journey, approach, philosophy, and market analysis - **Entrepreneur** (/entrepreneur/) - Entrepreneurship experiences and startup building - **Hobbies** (/hobbies/) - Sports, gaming, and other interests - **Foodie** (/foodie/) - Food experiences and culinary adventures ### Blog Categories/Tags - **tech** — Tutorials, guides, and technical articles about software development - **talks** — Tech talks, slides, videos, and event recaps - **portfolio** — Project retrospectives, open-source contributions, and case studies - **dailybot** — DailyBot collaboration platform (human + AI agents), Y Combinator experience, startup journey - **trading** — Trading journal entries, market analysis, algorithmic trading learnings - **personal** — Articles about life experiences and personal reflections - **entrepreneur** — Entrepreneurship experiences, startup building, and Y Combinator journey ### Blog Series #### Building XergioAleX.com (7 chapters) How this website was built from scratch with Astro, covering architecture decisions, performance optimization, analytics, content collections, multilingual support, deployment, and AI bot tracking: 1.

They are not published yet. ### Languages All pages and blog posts are available in: - English (default): / - Spanish: /es/ Each language has its own RSS feed, blog listing, and full page set. ## Content Model - Bilingual routing: English base routes (`/`, `/blog/`, etc.) and Spanish routes under `/es/` - Blog posts authored with Astro Content Collections supporting Markdown and MDX - Blog pagination: `/blog/page/{n}/` and `/es/blog/page/{n}/` - Tag archives: `/blog/tag/{tag}/` and `/es/blog/tag/{tag}/` - All pages use structured data (JSON-LD) for machine readability ## Topic Areas - DevOps, CI/CD, and infrastructure workflows - Software engineering and architecture patterns - AI, machine learning, and deep learning - Blockchain and distributed systems - Robotics and autonomous systems projects - Entrepreneurship and startup building (DailyBot, Y Combinator) - Algorithmic trading and financial markets - Tech community building and knowledge sharing - Personal productivity and team collaboration ## Tech Stack - Astro (static site generator with islands architecture) - Svelte (interactive components) - TypeScript - Tailwind CSS (with dark mode support) - MDX (enhanced Markdown for blog posts) - Biome (linter and formatter) - Deployed on Cloudflare Pages ## Interests & Expertise Sergio's areas of expertise and interest include: - Full-stack software development - Conversational interfaces and AI - Entrepreneurship and startup building - Algorithmic trading and forex markets - Community building and tech talks - Sports (cycling, running, basketball, chess) - Gaming and food content creation ## Agent-Friendly Markdown Endpoints All pages and blog posts are available as clean, native Markdown for AI agents. This content is served directly from the original source Markdown — not converted from rendered HTML — preserving full fidelity of code blocks, links, and formatting. ### URL Patterns - **Pages**: `/{page}.md` (EN), `/es/{page}.md` (ES) - Examples: `/about.md`, `/cv.md`, `/dailybot.md`, `/es/about.md` - **Blog index**: `/blog/index.md` (EN), `/es/blog/index.md` (ES) - Lists all posts with links to their `.md` versions - **Blog posts**: `/blog/{slug}.md` (EN), `/es/blog/{slug}.md` (ES) - Examples: `/blog/building-xergioalex-website.md`, `/es/blog/building-xergioalex-website.md` ### Response Format Each Markdown response includes: - H1 title - Description (blockquote) - Metadata: Published date, Language, Canonical URL (HTML version), Tags - Separator - Original Markdown body content Content-Type: `text/markdown; charset=utf-8` ### Content Negotiation Agents can request Markdown without changing URLs by sending `Accept: text/markdown`: ``` curl -H "Accept: text/markdown" https://xergioalex.com/about → Returns Markdown with Content-Type: text/markdown; charset=utf-8 → Response includes Vary: Accept header for proper caching ``` ### Why Native Markdown - Content is served from the original source files, not HTML→Markdown conversion - More token-efficient for AI consumption (no HTML tag residue) - Code blocks, links, and formatting preserved exactly as authored - Canonical URL always points to the HTML version for human readers - Internal cross-links between pages enable agents to discover the full site structure ## Feeds & Discovery - RSS Feed (English): /rss.xml - RSS Feed (Spanish): /es/rss.xml - Sitemap: /sitemap-index.xml - Search API: /api/posts.json - API index: /api/index.json - OpenAPI specification: /openapi.json - Developer portal: /developers - robots.txt: /robots.txt - This file: /llms-full.txt - Short version: /llms.txt ## Structured Data The site includes JSON-LD structured data on all pages: - WebSite schema (site-level identity) - Person schema (author identity and social profiles) - Organization schema (DailyBot association) - BlogPosting schema (individual blog posts with author, dates, tags) - BreadcrumbList schema (navigation hierarchy on all pages) - CollectionPage schema (blog listing pages) - ContactPage schema (contact page) - WebAPI schema (developer portal, describing the public JSON API)
