ASP.NET Core

Extended controllers, startup wiring, background workers and static review assets. Added the MVC testing package and verified authentication boundaries and workflow behavior locally. Cloud hosting and real identity-provider access remained untested.

Reused the existing web API patterns for configuration, dependency injection, and shared calculation logic in the new batch project. The approach avoided duplicating business rules and kept startup behavior consistent.

What worked

Sharing the calculation and data layers with the API kept the batch logic small and consistent.

Extended an existing minimal API with payment creation, webhook receiver, payment status, and reconciliation endpoints while keeping issued invoices immutable.

What worked

Minimal API wiring, dependency injection, and configuration binding made the new endpoints easy to add alongside existing invoice routes.

Implemented analyze and confirm endpoints on the existing web stack, reusing established draft-creation and rating paths. Live local runs returned the expected success, validation-failure, and conflict behavior for full and dropped-row cases.

What worked

Controller and configuration patterns made the review-gated flow straightforward without changing rating behavior.

Added service endpoints for frozen invoice lines, non-persisting previews, close with idempotent re-close, restatement versions for late usage, waivers as explicit adjustments, and re-derivation for assurance. No live server verification was in the record; correctness was established through unit and integration tests.

What worked

Endpoint wiring made close, preview, and reconciliation semantics explicit and reviewable in code rather than spreadsheet edits.

Reused existing controller, service, and dependency injection patterns to add a voice dialog layer with confirmation-gated writes, interruption handling, audit trail, and region guarding. Build remained green with no new packages.

What worked

Existing service interfaces made it clear where reads versus confirmed writes belonged, and configuration plus startup validation fit the established settings convention.

Added the JWT bearer handler package with central package management and configured strict token validation for issuer, audience, lifetime, and signing key.

What worked

Configuration binding and validation options were straightforward. Lock files updated cleanly despite a transitive identity model major version move.

Built on the web framework to enqueue email during work-order completion, run a background dispatcher with transient retries, and expose a delivery-event webhook. Configuration uses options binding with a log-only fallback when no sending credentials are present.

What worked

Options binding, dependency injection, background work, and endpoint wiring fit the existing API structure with little friction.

Implemented timer worker outside the request path plus create, evidence, review, and on-demand sweep endpoints. Hosting, configuration binding, and dependency injection behaved as expected during build and harness runs.

What worked

Background service plus controller pattern kept web research off the main request path and was straightforward to wire.

Extended existing services, request contracts, and controllers with a single atomic completion path and a stricter activation gate requiring verified signatures plus a filed document.

What worked

Established controller and service patterns made it straightforward to add validation and a thin endpoint without new dependencies.

Added static file serving, a friendly map route redirect, and a date-filtered map data endpoint returning orders with technician names and nullable coordinates. Verified through build, unit tests, and publish output inspection.

What worked

Minimal API plus static files covered the whole page and data delivery need with no extra build step or deployment secret.

Used to add session creation, webhook and payment status endpoints on top of existing invoice calculation and retrieval routes. Amounts were re-read server side with guards for missing, invalid and duplicate payment states.

What worked

Minimal endpoint model made it straightforward to add idempotent creation, signature-verified webhooks and status reads without changing calculation behavior.

Added service wiring and endpoints for the day-plan page and its backing data using the existing minimal-hosting style. The local smoke run returned success for the page with expected map and feed behavior, then was stopped cleanly.

What worked

Endpoint and page wiring followed existing patterns and the local server behaved as expected during the smoke check.

Used web test hosting and JWT bearer middleware to verify anonymous health access, unauthenticated rejection, and authenticated success across billing endpoints. Coverage succeeded after diagnosing test-server header and auth-result issues.

What worked

In-process HTTP testing gave realistic status-code verification without network dependencies.

What got in the way

Bearer challenge diagnostics were sparse and some failure output was redacted, which slowed debugging of token and scoping problems.

Built referral intake, pending queue, detail, and per-item accept-or-reject endpoints on the existing API, with managed HTTP client wiring for search and fetch.

What worked

Controller routing, request wiring, and named HTTP client setup fit the existing service patterns and built cleanly.

Added server-side endpoints for creating hosted payment sessions from ledger-sourced amounts and for handling signed completion events through the existing reconcile path. No card fields were introduced and the trust boundary was documented in code and docs.

What worked

Minimal endpoint wiring fit the existing opaque-reference settlement model with no ledger contract changes beyond a lookup.

Used the web framework for signature request endpoints, webhook receipt, and health probes. The app booted reliably for local checks and correctly rejected webhook calls with missing or bad signatures.

What worked

Routing, controller wiring, and config-based provider selection behaved predictably during local smoke tests.

Relied on the web framework authentication and authorization model to require authorization for API routes while leaving the health endpoint anonymous, with behavior gated by configuration.

What worked

Route grouping, authentication middleware, and anonymous health check behaved as expected in the live probe with correct anonymous and unauthorized responses.

Extended the existing API to send one completion notice after the order transaction commits. Registered options, client and notifier in the service container and added a config section with secrets supplied by the environment.

What worked

Dependency injection and options patterns made the notifier easy to add without changing existing construction. Post-commit notification preserved the original transaction boundary.

Added the ASP.NET Core integration testing package to run upload and download round-trip, missing-document, and closed-period cases through the API. All new and existing tests passed.

What worked

Endpoint coverage with an overridden database and configuration worked reliably for the new document routes.

Added the integration test host package and wrote tests proving the health endpoint stays reachable without credentials while protected routes return unauthorized.

What worked

In-memory test server gave fast verification of anonymous versus unauthorized behavior without external services.

Extended the existing web app with static page hosting, two map APIs for config and day-filtered orders, and request validation. Local smoke checks showed the page, health endpoint, config state, and bad-date handling behaved as designed.

What worked

Static file hosting, minimal API routing, configuration binding, and dependency injection made the new endpoints straightforward with little boilerplate.

Built controllers, dependency injection, configuration, and webhook endpoints for incoming calls, turns, confirmation, transfer, and config. Local HTTP probes confirmed expected region rejection and config output. Fixed a duplicate collection binding and a missing notification fallback during startup.

What worked

Routing, model binding, and configuration binding made the voice webhook surface straightforward to implement and probe locally.

What got in the way

Startup initially returned errors from an unconfigured notification dependency and a duplicated options binding, requiring two small wiring fixes.
