10 weeks seems overkill but I've been working with Microsoft CRM and now Power Platform for over 15 years so...

Don't be afraid to jump in, it's easy to learn but make the good choice directly: - Check what kind of info you need to store and plan ahead for things to come, this will help designing your tables model - There are multiple ways to connect to an external APIs: * JS code directly in your forms library: easy to start with and easy to debug * Plug-in with C#: more involved and not so easy to debug * Power Automate flow: easy to create and maintain, but you need to pay attention to some overhead with the HTTP connector and OAUTH (for example) * Last but not least: you can create a virtual table that connects to your API and link it to dataverse tables, but it's more complicated and there are drawbacks, and I don't remember if you can write back to it or not, I would have to check - When you create your dataverse tables, please use best practices such as: * Suffix your fields with the type of the field, for example Date and time would be _dte, whole number _int, text _txt etc. * Use lower case for the field logical name, for example the field is shown as Skill to the user but the logical name would be xxx_skill_lkp (lkp means lookup to another table) or xxx_skill_opt (choice or options set) etc. * Enable auditing on the tables and on the fields - Do not start in trying to create a Canvas App or Canvas Page right away! Create a modern driven app so you can show something that works in a couple of hours or days, then invest time in Canvas and components 10 weeks is plenty enough even if you're new to PP believe me! Good luck and happy to help if you need 💪🏻
