Overview
A production-oriented automation system designed to coordinate repeated appointment workflows across multiple accounts while managing authentication, scheduling, email-based verification, notifications and failure recovery. The project grew beyond a simple automation script because the real challenge was not making a single request work. It was keeping multiple workflows reliable over time.
Problem
Manual appointment monitoring was repetitive, time-sensitive, difficult to scale, vulnerable to missed opportunities, and difficult to coordinate across multiple accounts.
- Perform recurring checks without relying on manual triggering
- Keep account state isolated so one workflow could not corrupt another
- Handle authentication and session expiration as part of the workflow
- Process verification emails and notify users in time to act
- Recover from transient failures and continue when one workflow failed
Constraints
- Multiple independent account states
- Recurring execution over long-running processes
- External service dependencies
- Authentication and session expiration
- Time-sensitive actions
- Network failures and availability variability
Solution
Built a manager/worker architecture: a coordinating layer scheduled and managed work while account-level workers handled individual workflows.
External services were integrated for email verification, notifications, availability data and account actions.
Retries, logging and session handling were treated as part of the system, not as afterthoughts around a script.

Technical Decisions
Why a worker-based architecture?
The workflows were independent and failure in one account should not stop the others. Separating work by account also simplified state handling and retries.
Why scheduled background execution?
The system needed to run continuously without requiring a user to manually trigger checks.
Why external notification integrations?
The output of the system only had value if users could act quickly on time-sensitive results.
Reliability / Failure Handling
- Account isolation so a failed workflow did not stop the rest of the pool
- Retry strategies for transient network and API errors
- Session expiration treated as recoverable state rather than a hard stop
- Logging to make stalled or partial failures visible
- Scheduled execution so the system kept running without manual intervention
Result
The platform supported more than 1,000 successful appointment workflows and became an operational system used beyond development/testing.
What I Learned
The project reinforced that automation reliability is mainly a state-management and systems problem, not simply a browser-control problem.
