Struggling with Project Documentation and Application Flow – Need Advice

Hi everyone,

I’m currently leading a small team 2 developers to develop an application for HR system. While we’ve made good progress step by step—creating endpoints, testing functionalities, and ensuring things work—it’s becoming clear that the lack of documentation and planning upfront is causing issues.

Here’s the situation:

There was no design flow, wireframe, or documentation created at the start of the project.

Now I’m struggling with the overall application flow—how components should connect, how the backend integrates with the frontend, and how the frontend should look.

We’ve been working based on personal experience and immediate needs, but I’m realizing that a structured approach is now critical.

Could anyone recommend:

• The type of professional I should hire to help with this (e.g., project manager, UX designer, technical writer, or someone else)?
• Resources or tools that could help me improve the current situation?
• Any best practices for structuring this kind of documentation and planning moving forward?

I’d love to hear from others who’ve been in a similar situation or have expertise in application development and project management. Any advice would be greatly appreciated!

Thanks in advance!
