Adds .portfolio/project.md, which holds everything kgu.one shows for this project: the one-line description, the summary paragraph and the full write-up on the project page, plus the date, award, stack and links. The file is a byte-for-byte copy of the site's current text, so merging changes nothing on the site. After the merge, this repository becomes the source for that text, and the site copies the file from the default branch once a day.

node /tmp/kgu-portfolio/check.mjs validated the file against the entry format: required keys, date, line length, a 50 to 80 word summary, a write-up under 1,500 words, https links, and no em dashes or middle dots. gh api confirmed the pushed file equals the site's copy.

📝 Walkthrough

Walkthrough

Added .portfolio/project.md with Connvo metadata, links, editorial requirements, and a first-person description of its features, backend, access controls, and division of work.

Changes

Portfolio entry

Layer / File(s) Summary
Add Connvo project metadata and description
.portfolio/project.md
Adds portfolio-page editing requirements and Connvo metadata. The first-person write-up describes matching, queue handling, backend services, access controls, and the stated division of work.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~4 minutes

Change: Other

Merge Risk: 🔵 Low · up to 7bb3b

The new portfolio entry could mislead readers about access controls, matching, and queue timing. The issues are confined to public copy, so the change presents low merge risk, though correcting the descriptions would improve accuracy.

Architecture Summary

Architecture risk: 🔵 Low · up to 7bb3b

The changed surface does not map to a changed system, dependency edge, entrypoint, or external dependency.

Fix with agent prompt
### Issue 1
.portfolio/project.md:23
The entry describes scored matching that leads to a hosted coffee chat, but the professional queue shows a hard-coded match after a timer. Accepting it redirects to a page with mock participants and messages without creating a meeting. Readers may expect a real match and call from this flow. Please qualify the copy as a prototype or describe what the current flow does.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

### Issue 2
.portfolio/project.md:23
“Calls run on Stream video” makes Stream sound like the provider for every meeting. Meeting creation instead selects WebRTC unless the organizer is on a paid plan and requests a large or recorded meeting. This gives readers an inaccurate picture of the video setup; please describe both providers.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Summary

Adds a portfolio entry intended to supply Connvo’s project page, including its metadata, links, and feature description.

  • The entry’s description should distinguish the implemented backend and demo user flow, and accurately describe the video-provider selection.

Connvo sets up one-on-one video coffee chats between people whose interests, goals and experience fit. With Andrew Wang, I wrote most of its Convex backend. The matching queue scores each pair on shared interests, complementary experience and roles, and embedding similarity, then explains the score. Calls run on Stream video, sign-in on WorkOS, and every meeting has permission checks and an audit log.

Narrow the universal permission and audit claim.

createMeeting permits unauthenticated creation when an existing organizerId is supplied, without checking ownership. Lifecycle creation and transitions do not write audit records. Stream webhook events do write audit records, and participant or host operations check access, but this does not support “every meeting.”

Suggested wording update
-Calls run on Stream video, sign-in on WorkOS, and every meeting has permission checks and an audit log.
+Calls run on Stream video, sign-in on WorkOS, and supported participant and host operations enforce access checks; Stream call and recording events are written to audit logs.

Connvo is built around one conversation at a time, so a match has to be worth showing up for, and both people should be able to see why it was made.

## How a pair gets scored

The matching engine scores each pair on eight features, weighted by default like this:

- Shared interests, 25%
- Embedding similarity between the two profiles, 20%

Clarify that time-zone compatibility is currently a placeholder.

The matching scorer currently sets timezoneCompatibility to 1.0 for every pair. The project description therefore implies behavior that is not implemented. State that time-zone compatibility is planned or currently a placeholder.

Correct the outcome-analysis description.

The optimizer excludes accepted records. It uses only completed and declined records, treats completed as success, and calculates feature correlations before proposing weights. Update the copy to describe those inputs accurately.

Suggested fix
-Accept, decline and completion outcomes feed an analysis that measures how well each feature predicts a successful match and proposes new weights from that.
+Completed and declined outcomes feed the weight optimizer. It treats completed outcomes as success, measures each feature's correlation with that outcome, and proposes normalized weights.

You tell the queue when you’re free, and an entry expires on its own once that window passes. The queue is processed in shards, and match creation uses optimistic concurrency to prevent race conditions.
