This is a personal portfolio with real machine-readable surfaces. Every endpoint listed below is live. Read operations do not require auth. Anonymous user-initiated agents (ChatGPT-User, ClaudeBot, PerplexityBot, etc.) are welcome; training-only crawlers are disallowed.

If you only have time to fetch one thing: GET <https://www.gabrimatic.info/api/profile>. It returns the structured profile in about 3 KB.

If you speak MCP or A2A, start from the discovery cards under <https://www.gabrimatic.info/.well-known/>. Both protocols accept anonymous reads.

## Site runtime

- Framework: Flutter Web `3.41.8`
- Dart: `3.11.5`
- Engine revision: `59aa584fdf100e6c78c785d8a5b565d1de4b48ab`
- Machine-readable source: `portfolioSite` inside <https://www.gabrimatic.info/api/profile> and the MCP `get_profile` tool.

## Structured data (JSON, no auth)

- [Profile](https://www.gabrimatic.info/api/profile): schema.org/Person. Name, location, current roles, links, expertise, languages, contact preferences, and portfolio runtime metadata.
- [Professional journey](https://www.gabrimatic.info/api/journey): schema.org/ItemList. Nine roles. Affinidi is pinned at position 1; the rest stay reverse-chronological.
- [GitHub repositories](https://www.gabrimatic.info/api/repos): live proxy of `api.github.com/users/gabrimatic/repos`, edge-cached for 5 minutes. Each repo includes a server-side `category` (ai, flutter, native, other), a nullable `priority` from 0 to 5 for curated portfolio ordering, and a `hidden` flag showing whether the portfolio UI surfaces it.
- [Merged open-source contributions](https://www.gabrimatic.info/api/contributions): live proxy of GitHub merged pull requests authored by `gabrimatic` outside owned repos. Each project includes `name`, `fullName`, same-origin `logoUrl`, `mergedPrCount`, and a GitHub URL filtered to merged PRs by Soroush in that repository.

## Live agent protocols

- [Model Context Protocol server](https://www.gabrimatic.info/api/mcp): Streamable HTTP, JSON-RPC 2.0, protocolVersion `2025-03-26`. Discovery card: <https://www.gabrimatic.info/.well-known/mcp/server-card.json>. Tools: `get_profile`, `get_journey`, `get_repos`, `get_page_markdown`. POST any JSON-RPC `initialize` / `tools/list` / `tools/call` request directly; no session header is required.
- [Google A2A endpoint](https://www.gabrimatic.info/api/a2a): JSON-RPC 2.0, protocolVersion `0.3.0`. Agent card: <https://www.gabrimatic.info/.well-known/agent-card.json>. Methods: `message/send`, `tasks/get`, `tasks/cancel`. The card lists four skills with example user queries.
- [WebMCP](https://www.gabrimatic.info/webmcp.js): in-page tool registration via `navigator.modelContext` for browser-resident agents.

## Markdown alternates (for LLM scrapers)

Every page route returns Markdown when the request carries `Accept: text/markdown`; direct `*.md` URLs are equivalent. `Vary: Accept` is set on every negotiated route.
