What this site publishes
This site is a portfolio and writing space: a showcase of selected projects, a blog on engineering, tooling, and process, and a record of certifications and developer programs. The about page covers work experience, education, and the technology stack in day-to-day use; the contact page lists the email and social channels to reach out on for freelance work, collaboration, or open source.
For AI agents and developers
Everything here is also published in machine-readable form, so people and AI agents alike can read it without executing JavaScript. Markdown surfaces include /llms.txt for the complete site context, /agents.md for an agent-ready profile, and /sitemap.md as a semantic page index — and any blog post serves raw Markdown when .md is appended to its URL. A public, read-only JSON API at /api/v1 exposes the same content as structured data, described by the OpenAPI 3.1 specification at /openapi.json; no API key is required, and the versioning, deprecation, and rate limit conventions are documented on the developers page.
