There are cases where a bloated software with a GUI is not always needed. Rather, a software with a text based user interface (TUI) or a command line interface is required. A good Java library capable of implementing a text-based user interface (TUI) similar to the famous command line tool “midnight commander” is Lanterna. Another option involves using Java Picocli which makes it possible to create command line tools such as git, tar, etc. Command line tools are great for developing software used by scientists to perform some calculations. If necessary, the command line tool will perform concurrent calculations.

On the other hand, there are cases in which a software with a GUI is more appropriate. JavaFX should be taken into account if an interactive simulation machine for topics related to chemistry and physics is needed. Of all the Java GUI frameworks out there, it is the one that is the most advanced. It allows for a liquid layout. What’s more, the visualisation of (large) data sets such as the temperatures of a specific region during a certain period of time can be realised by sticking to web applications using the Haskell framework yesod.

This gig involves creating software useful for scientific or research purposes in chemistry or physics related topics.

What I can do else for you:
- creating a command line tool using Haskell or Java which will perform concurrent calculations
- To visualise data the gnuplot library can be imported in a Haskell or Java command line tool. The frontend will be realised by Java Picocli, Java Lanterna, or a Haskell library suitable for command line tools. You will be able to run the compiled Java or Haskell program in the terminal just like any other utility
- developing a Java simulation machine with a graphical user interface realised by JavaFX. This software will be able to simulate chemical or physical reactions by making use of a chart library for scientific purposes
- developing a web app using the Haskell framework Yesod. The web app is suitable for displaying (large) data sets such as temperature figures by using available chart libraries

Please take into account that the program will be delivered as a Maven, Stack or Python project which will include the source code. Additionally, I support MySQL, SQLite and MariaDB database systems.

For $17.50, I can develop a customised command line software performing calculations using Haskell or Java. This price is valid for the implementation of three main functions.

For $29.16, I’ll create a command line tool in Haskell / Java or a TUI in Java. It’s suitable for visualising data that consists of (large) data sets that were collected during experiments. This price is valid for the implementation of three different diagrams.

For $46.66, I’ll develop a simulation suitable for applying chemical reactions or physics processes using Java and JavaFX respectively. This price is valid for one main function including one diagram.

For $58.32, I’ll implement a web app written in Haskell. The web app is able to display (large amounts) of data sets collected during experiments. This price is valid for one main function including one diagram.

For an extra $5.83, you can add a diagram.
For an extra $5.83, you can add another functionality to your program.
