Java code for CPM & PERT Visualization for project management

I'm in need of a Java expert to develop a CPM & PERT visualization tool for project management.

There are multiple sources of code online about the relevant algorithms needed to execute the CPM&PERT methods in Project Management. I will also send you material and lectures(via private message) on how to calculate the result of CPM&PERT techniques Follow the examples of the lectures sent to you, to understand how the visualization of the network will be.

I will proceed to the payment in 4 stages, or every milestone reached,after you deliver to me the requested task deliverables.

This tool should meet the following requirements:

- Support Manual input, as well as the ability to Import from CSV and Excel files. It should also load Work-Breakdown Structure (WBS) or table.
- Show critical path, activity durations, and dependencies.
- Generate CPM & PERT networks.
- Graphically visualize CPM & PERT networks.
- Generate PERT chart in java swing
- Include Project-level summary, Task-level detail, and Resource allocation and the tool should be able to perform Project crashing based on Economic Dimension of the Project.

Ideal candidates should have:
- Proficiency in Java and experience in developing similar visualization tools.
- Strong understanding of project management concepts, particularly CPM & PERT.
- Experience in working with different input data sources and formats.
- Familiarity with Project Management tools, specifically Project crashing.

Apart from the code,you also have to deliver:

a README File

Overview: A brief description of the project, its purpose, and its key features.

Installation Instructions: Step-by-step instructions on how to set up the environment and install any necessary dependencies.

Usage Instructions: How to run the code, including any necessary commands or scripts.

File Structure: An outline of the directory structure and a brief description of each major file or folder.


Documentation:

User Guide: Detailed instructions on how to use the software, including examples and expected outputs.

Code Comments:
Ensure that the code is well-commented, explaining the logic, important functions, and any complex sections of the code.
You should also deliver a very short report (a pages at most) describing what every function does and with descriptions outlining which functions were implemented in the code.


Sample Data: Include a small set of sample data that can be used to test the code.
Configuration Files: Any configuration files required to run the code
Testing: Test Scripts: Any test scripts used to validate the code.
Test Data: Data sets used for testing the code, along with expected results.
Instructions: Instructions on how to run the tests and interpret the results.
