Sunny Yuen

Sunny Yuen is an independent full-stack engineer who operates a self-sovereign "Resume Agent": a machine-queryable professional profile served from agent.yuens.me for employer AI systems, ATS tools and personal assistants. The surface is an anonymous six-operation REST API described by a published OpenAPI 3.1 document, a public remote MCP server exposing an ask_candidate tool, and an A2A 1.0 agent card, with the agent's identity tied to the yuens.me domain through an Ed25519 fingerprint published in DNS (Open Employment Protocol Phase 1). The software is MIT-licensed and published as a fork-ready reference implementation.

Sunny Yuen publishes 6 API contracts indexed on the APIs.io network, including Availability API, Info API, Match API, and 3 more. Tagged areas include Company, AI Agents, A2A, MCP, and Resume.

Sunny Yuen’s developer surface includes engineering blog, GitHub presence, support, changelog, and 17 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/yuens-me: open an issue to ask a question, or submit a pull request to add artifacts.
