I focused on pragmatic development, security, and coding standards over feature richness. I refactored where necessary to align with framework conventions, wrapped critical operations in transactions to prevent race conditions, and added database indexes for performance. I included an example implementation of structured logging, tracing on the import pipeline, and unit tests for validation. For the most part, trade‑offs are intentional, not overlooked. I've used devcontainers to develop and test the project.

Commits are separated by business logic, and I tried to keep them as readable and as small as possible.

In consecutive 3‑hour blocks:

• RE‑001 completed + polished
  • fix: 6f05556, b2f4158
  • feat: c971d69
• RE‑002 completed
  • feat: 16a257f
• RE‑003 completed + polished
  • refactor: dd18409
  • feat: 4f8dff0
  • fix*: 418b910

In distributed extra 3 hours:

• RE‑004 completed
  • feat: 02fe6fc
• RE‑005 completed + polished
  • feat: 0cddc40
  • chore: acefe00
• RE‑006 completed
  • feat: 98772c1
• Extra polishing
  • test: 0f1609f
  • log: 799f2e1

Task Report

The commit log is mostly a representation of the time I spent from the first commit, and it shows that I started with minor refactoring, then the implementation of RE‑001, followed by RE‑002, then more polishing before implementing RE‑003.

I took the full 3 hours, with most of my time spent on RE‑001, RE‑003, and RE‑005, along with their related polish work.

Lastly, I spent some time creating example implementations of structured logging and unit tests, which I think must be done to show production‑level readiness for a project I (virtually) own.

To Be Improved Notes

Security & hardening

• Restrict CORS from AllowAnyOrigin to known frontend origins; add request‑validation middleware and rate‑limiting on POST /staff/login to prevent brute‑force.
• Replace hardcoded staffAccessCode with a secrets manager, introduce a Staff table with per‑user credentials plus audit trails for room‑cleanliness changes, and implement proper email sending (e.g., SendGrid, SES) instead of showing codes to staff.
• Harden file upload security with server‑configurable MAX_FILE_SIZE, binary content sniffing beyond the .csv extension, and a health‑check endpoint for orchestrators.
• Use a durable store (Redis or DB table with TTL) instead of in‑memory verification codes, and migrate from SQLite to PostgreSQL or similar in production since SQLite is single‑writer.

Code quality & design

• Replace exceptions‑for‑control‑flow (e.g., NotFoundException) with result types or similar; use FluentValidation for declarative, testable rules instead of custom extension methods.
• Organize code by adding an Api prefix to namespaces, pluralizing controller names, and placing DTOs in a dedicated folder.
• Avoid down‑migration‑script gaps and keep SQL queries optimized (e.g., prefer cursor‑based pagination over LIMIT/OFFSET and tighten queries where possible).

UX & observability

• Add a dedicated housekeeping page with filters (dirty‑only, floor grouping) and ensure every staff action that changes room state is logged for audit and traceability.

Delivery & operations

• No deployment pipeline yet; add CI/CD for build, test, migration, and deployment automation.
• Documentation is limited; update setup, architecture, API, deployment, and runbook docs.
