Nail Salon API Automation (looking for vietnamese coder)

Looking for vietnamese coder.

I need a Node.js script that can log in to our online nail-salon booking platform with staff credentials, discover its private REST API, and then use that same API to tweak appointment lengths on the fly.

Scope of work
• Authenticate with the site using the provided username/password pair (no public API key is offered).
• Pull upcoming appointments, including technician, start time, current duration and any other fields your logic needs.
• Apply our simple business rule: add or subtract minutes per technician so calendars stay realistic.
• Push the updated time blocks back through the same private endpoints, confirming changes were accepted.

What I will hand over
– A test account on the live system as soon as the project starts.
– The minute-adjustment table for each technician.

Deliverables
1. Clean, well-commented Node.js source (TypeScript is fine, plain JS also acceptable).
2. A README that explains installation, environment variables, and a one-command way to run the script (npm script or Docker).
3. Short PDF or Markdown file documenting every discovered endpoint and payload you used so future devs can extend it.
4. A quick screen-capture or log transcript proving the tool updated at least one appointment end-to-end.

Acceptance criteria
– Script runs on my VPC, modifies sample bookings exactly as per the rule set, and leaves no orphan data.
– No third-party services other than open-source libraries (axios, puppeteer, cheerio, etc.) without prior approval.

Timeline & payment
Two weeks total. I’ll fund the full amount (up to $1,500) immediately; the milestone releases once the script is running on my side with all docs delivered.

If you have experience scraping or reverse-engineering private REST flows, let’s get started.
