I research problems, build the software, and publish the evidence. Current focus: Recall Relay, a working Alexa+ concept that passes a product recall to the person who owns the appliance now—and keeps their next step for later. Try the handoff · Watch the 2:35 demo.
My favorite kind of problem: “This works most of the time.” The interesting work is finding the missing case, fixing it, and leaving a clear handoff.

Just shipped: Recall Relay. Sam gives Alex a cooker; its pressure lid is recalled. Share the notice, check the physical label, prepare the official free-lid request, and resume when the replacement arrives. A real MCP assistant advances the same open screen across two conversations. One real US recall, a sample household, and a complete browser journey. Source + local MCP setup ↗ · Hands-on guide ↗
Extracted and reused: Relay State. A small MIT-licensed Node.js library for serialized state changes, atomic saves, and live committed snapshots over SSE. Recall Relay uses it; Return Desk demonstrates an independent MCP integration. Install release 0.1.1 ↗
From the research desk: A tender changed. What happens to signed-off work? — three real notice changes, five proposed task actions, and a recovery design that preserves a teammate's concurrent update. Inspect the original JSON, download the review plan, and challenge the proposed transitions. Pre-build research · application development starts 22 October. Build and evidence plan ↗
Open collaboration: Help shape BidDelta as a hands-on product / UX co-creator. Start with one change you would make to the five-task plan; build window October 22–26.
Self-initiated tools and runnable engineering samples:
-
n8n-check — Run a workflow against HTTP mocks in real n8n. Assert the outgoing requests and output items; get JSON + JUnit. Use the GitHub Marketplace Action for a one-file CI setup with readable check summaries and request traces. Build a case from your own export — locally in your browser ↗. On npm:
npm install --global @blucca/n8n-check(Node.js 24+). -
FlowDelta — Turn n8n workflow changes into release notes, acceptance checks, and a client-ready handoff. Comparison runs in your browser. Source ↗
-
Document Approval Gate — Correct → approve → lose the ERP response → retry. Try the 60-second browser simulation, or use the real-PG review desk and n8n caller. 13 executed backend scenarios, synthetic ERP. Source + local setup. Recorded results ↗
-
Arc Receipt Reconciler — Match USDC receipts to invoices, with explicit duplicate handling and partial payments. A local-first, read-only prototype. Source ↗
Upstream work: HubSpot CRM card converter — preserve target URL query parameters. Submitted patch with regression tests; follow the PR for review status.
Try it now: Your HubSpot card renders. Does the action work? — reproduce the converter URL regression in your browser, then check the backend contract.
New from the workbench: Two tool calls. One duplicated ID. — inspect real n8n checks for Vapi-shaped responses: identity pairing, backend 503, empty orders, and a wrong-ID regression.
From the workbench: Two items. One failure. Four requests. — compare recorded traces from direct retry, HTTP batching, and a one-item loop. Runnable workflows and the fix included.
