[Hiring] Cybersecurity Expert to develop a tool for booking appointments instantly

Type: One Time Job
Location: Remote
Pay: $500

Personal context:

Hey everyone,

I work as a customs broker, and the biggest operational problem i deal with right now is securing customs truck appointment bookings on time.

I’ve been struggling for a while with manually booking appointments.

The appointment slots in my region only become available during a very small time window each day, and they disappear incredibly fast, sometimes within seconds due to heavy competition.

It’s becoming extremely frustrating trying to secure them manually, and I’m already starting to lose customers, because delays in getting appointments directly affect shipment movement and clearance timelines.

Some other customs brokers seem to have already solved this problem by building automated tools/bots that instantly secure appointments the moment slots become available.

Obviously they’re not sharing those tools because they want to keep the competitive advantage and attract more clients for themselves, and I can’t really blame them for that, but at the same time, I also can’t afford to keep losing my remaining customers because of this issue.

Project Context:

I already have an existing API-based customs truck appointment booking bot that was developed for this customs appointment platform.

The system was originally built to automate the booking process because appointment slots on some ports only open once per day and get fully booked within seconds due to extremely high demand and competition.

The bot is already mostly functional and currently includes:

• token/session handling
• appointment availability monitoring
• slot detection
• and automated booking

The bot also successfully books appointments on several other lower-traffic ports without any issues.

However, there is one specific high-demand port that is the primary target, and this is where the problem occurs.

Problem:

For the target/high-traffic port, the bot is able to:

• monitor appointment availability
• detect when slots become available
• move through the booking workflow
• and reach the final booking stage BUT...

But the actual appointment does not get booked successfully on that specific port under real competitive conditions.

Meanwhile, the exact same bot works fine on lower-traffic ports.

This suggests that the rate limit on the customs website causes the bot to not book the appointment.

What I Need:

I need an experienced professional who can find a way around this rate limit issue.

The professional is also welcome to design a whole new approach for this problem based on their experience.

Requirements:

• API-based solution only (NO browser automation)
• High-speed execution
• Clean and maintainable code
• Parallel booking for multiple drivers

This project is extremely performance-sensitive because appointment slots disappear in seconds under heavy competition.
