...computer networks. PDA based flexible ticket system You are going to implement a prototype of a flexible ticket system. In its complete version it is going to replace the current RF-id tag based system. The new system expected lifetime is 5 year only. In 5 years it is expected that face recognition has advanced sufficiently to allow ticketing based entirely on automatic unattended image processing. While the proposed system only partly reduces the manual control, it will reduce the amount of sign in /sign out equipment on platforms and placing that equipment entirely in the rolling stock. Each train compartment or bus is already equipped with a wireless LAN connected to the InterNet. The train or bus computer knows the current position (GPS). A passenger simply assoc...

...now needs a focused round of improvements. My immediate priority is the payment system: I want a one time subscription option configured end-to-end, keeping the door open for monthly, quarterly or annual plans and a free-trial mechanic that I can switch on later. This includes product setup, workflow tweaks, invoicing logic and whatever Stripe or Braintree hooks are required inside Bubble. In parallel, every task created in the CRM has to appear automatically in Google Calendar for the assigned user. I already have a Google account ready; what I need from you is the full OAuth handshake, event-creation workflow and a way to keep edits in sync both ways so users always see the latest due date. Finally, a handful of buttons and on-screen actions need to be relabelled or repurpose...

I have a set of Automation Anywhere A360 bots that currently handle web automation, Excel processing, and email handling. I now need every one of those workflows rebuilt in Microsoft Power Automate—both the cloud flows and Desktop (PAD) components—while preserving the same business logic and performance. Here is the flow of work I expect: 1. Analyse the existing A360 packages to capture every step, variable, credential, and dependency. 2. Re-create each bot inside Power Automate, introducing structured error handling and logging so exceptions are surfaced clearly in run history or via alerts. 3. Set up test cases, walk through them with me, and adjust until each migrated flow produces identical results to the original A360 version. 4. Package the final solutions ...
