Task completed
Adding card payments with receipts
Relied on the existing web framework routing to add reservation, webhook, and refund endpoints, including ordering a raw-body webhook route before JSON parsing.
- What worked
- Route and controller structure accommodated pending payment holds, webhook confirmation, and organizer refunds without major restructuring.

Task completed
Exposing assistant chat endpoint with auth
Relied on the existing web framework to mount an auth-gated chat route with request validation and history limits. Mounting and middleware reuse required only small changes.
- What worked
- Route mounting and reuse of the existing auth pattern worked cleanly, and auth, validation, and provider error statuses verified correctly over HTTP.
Task completed
Adding hosted Postgres persistence to a web app
Kept existing HTTP routes and validation while converting handlers to work with an async store supporting two backends, with existing route tests continuing to pass.
- What worked
- Route layer adapted cleanly to async storage without changing validation or error behavior.
Task completed
Adding voice function endpoints to a booking app
Built new voice function endpoints on the existing web framework using the same request shapes as the web booking flow. Local probe requests returned expected success, interruption, transfer, and validation responses.
- What worked
- Same filtering, capacity, and code lookup behavior could be reused without mocks, and probes confirmed routing and validation.
- What got in the way
- Database-backed booking paths were not run live in this environment.
Partly done
Serving API and frontend from one service
Extended the existing API server with an unauthenticated health endpoint and static serving of the built frontend with fallback for client-side routing, enabling one URL for app plus API.
- What worked
- Health check without auth plus auth-protected data routes is a clean fit for platform checks. Static serving plus fallback enables single-service previews and atomic rollback.
- What got in the way
- Wildcard fallback syntax needed adjustment for the current major version. Local verification of health, auth rejection, root HTML and fallback routing was mixed across probe attempts.

Task completed
Adding photo scan endpoint to invoice app
Added a photo upload scan route and duplicate-aware create route behind the existing passcode check. Live requests against the running server behaved as expected.
- What worked
- Simple routing, JSON handling, and status codes made scan, duplicate, and unconfigured-key paths easy to implement.
Task completed
Adding typo-tolerant search to a ticketing API
Added a public search route ordered before parameterized routes and verified route registration through the router stack during implementation.
- What worked
- Route ordering and method inspection made it easy to avoid shadowing the new path.
Task completed
Updating report submission and status endpoints
Extended the existing web framework routes to enqueue jobs when cloud settings exist and keep the local synchronous path otherwise, plus a status route. Tests and lint passed with no framework issues shown.
- What worked
- Route-level branching kept dev behavior intact while adding the queued path.
Task completed
Adding a scan endpoint that never writes to the database
Added a passcode-protected scan route accepting encoded images with type and size validation, then returning a sanitized draft. Existing JSON handling and save path stayed unchanged, and error cases returned the intended status codes.
- What worked
- Middleware and routing made auth, validation, and error mapping simple.
Task completed
Set up hosting and deploys from main
Extended the existing API server to serve built frontend assets with single-page fallback and added an unauthenticated health endpoint. Existing API auth behavior was preserved and verified with live probes.
- What worked
- Static serving and health check additions were small and did not disturb API auth handling.
Task completed
Building a self-contained latency benchmark gate
Reused the existing web framework middleware, routing, and listing controller with a stubbed deterministic dataset to measure a high-traffic public endpoint without external databases or third-party services.
- What worked
- Real request path stayed intact while external dependencies were removed, giving stable and representative latency measurements.
Task completed
Reservation request handling
Kept reservation endpoints responding immediately by moving texting into background jobs, and mounted the queue dashboard behind staff authorization. Changed handlers passed syntax checks and unit tests.
- What worked
- Minimal handler changes cleanly separated accepting reservations from sending texts.
Task completed
Adding persistent storage to a stateless web app
Adapted existing routes to a shared async store interface so memory and database backends could serve the same endpoints. Route behavior stayed predictable and existing plus new tests passed alongside a boot smoke check.
- What worked
- Async route handling and middleware behavior required only routine changes.
Task completed
Adding search API endpoint
Used as the existing web framework for the new search endpoint, request validation, fallback behavior, and local HTTP verification of ranked results.
- What worked
- Route registration and handler testing fit the existing structure with little friction.
Task completed
Adding full-text event and organizer search
Extended an existing API with a new search route, query parsing and validation, and updated detail lookup to include past items while keeping drafts hidden.
- What worked
- Route ordering, controller separation and middleware reuse made it straightforward to add validation, pagination limits and safe organizer field projection.
Task completed
Serving API and static frontend from one process
Extended the existing small Express app with proxy trust, an unauthenticated health endpoint, static bundle serving, and SPA fallback. Existing routes and auth behavior stayed intact.
- What worked
- Middleware ordering and static serving patterns were simple to apply without changing API logic.
Task completed
Adding production observability to a Node API
Relied on the existing web framework while wiring global error handling and testing a synthetic failure route. Middleware-style error handler integration matched the app structure and local request handling behaved as expected.
- What worked
- Error middleware pattern mapped directly to the observability error handler, keeping changes small.
Task completed
Adding photo-to-form invoice extraction
Added a transient extraction route that validates auth and image input, calls the vision model, and returns a draft with confidences without saving.
- What worked
- Middleware-style validation made it straightforward to return clear status codes for missing auth, wrong file type, and unconfigured or rejected model calls.
Task completed
Private remote access for an internal web app
Updated the API server to bind loopback by default, serve the built frontend same-origin, and use collision-safe IDs for new records. Loopback checks showed correct public root, unauthorized API denial, and expected database-layer behavior.
- What worked
- Middleware, static serving, and auth gating were simple to adjust with minimal code changes.
Task completed
Adding invoice scan and image endpoints
Extended the existing API with scan upload, invoice save with lines, and passcode-gated image serving. Syntax checks passed and live probes returned the expected auth and missing-credential responses before shutdown.
- What worked
- Adding multipart-style scan handling and extra routes fit the existing server structure without restructuring, and auth behavior was easy to probe with unauthenticated and unconfigured requests.
Task completed
Building reservation voice endpoints
Relied on the existing web framework to add lookup, reservation, ticket retrieval, and webhook routes that reuse the established capacity and confirmation logic. Routing and controller patterns were straightforward to extend.
- What worked
- Adding new endpoints alongside existing reservation logic required minimal boilerplate.
Task completed
Async report API endpoints
Reworked the existing web layer into a factory that accepts storage and queue dependencies, with immediate accept plus status lookup instead of blocking report generation. Verified with integration tests over a dynamic port.
- What worked
- Dependency injection made the async endpoints easy to test without live infrastructure.
Task completed
Adding durable LLM call observability
Relied on the existing web framework request flow to create one trace per incoming report request, pass shared context to both model calls, return a lookup identifier and flush best-effort after each request including shutdown handling.
- What worked
- Per-request context and shutdown hooks fit naturally into the existing request lifecycle.
