I am currently in a BootCamp trying to work on a capstone project. I am in the AF Reserves and we use a site that you can enter information in and it is supposed to take that information and use it to populate a fillable PDF. Unfortunately, that feature doesn't actually work and I am wondering if this is something I can build using the CRUD stack I have learned of JS/CSS/HTML/Node.js/PostgreSQL and how to even approach doing it. Before I even begin working on the front in and the data capture I wanted to know if there is even a way to transfer the data I am collecting and transfer it to the fillable form.

If there are methods using other languages I would greatly appreciate the knowledge of how to do it in them. I want to improve the military process as it's a big function of my job and right now a redundant process of filling out all the information on our site and then manually having to fill out the pdf as well.

Thank you for your help and knowledge.

EDIT: To be more direct. I want to build a front end that takes in the data through a form. From there store it in a database. The process I have the question on is how to take that data either from the front end or database and input that in a PDF form(a pre-built standard form that has designated fields and data types typically filled out manually) within the stack I am currently working with. If it's not possible within these languages/stack, what do I need to learn for this function(populate pdf form with inputed data on a webpage) to work.
