Application development

I believe that in life, you should offer rather than take—what you receive, you also have to offer. That's easy to say when you have your essential needs covered.

It's my dream for a better world.

Technological resources

The more technological resources you have, the greater your ability to create.

The greater the variety of ingredients available, the more elaborate and flavorful your dishes can be.

IDE

Select your preferred IDEs: IntelliJ, PyCharm, Visual Studio Code, NetBeans, Eclipse, or vi

Programming language

The programming language is important (Java, Python, VB6, bash scripting)

Design patterns

Design patterns promote modularity in software design. Some examples of these patterns include Composite, Facade, Proxy, Wrapper, Strategy, and Visitor.

Database

Data persistence is sometimes crucial and is achieved through file systems and databases like Oracle, MySQL, and MongoDB.

Web services

When the application needs to use modules from other languages, utilizing them as a resource in a remote server via a REST API can be beneficial. Various servers, libraries, and web frameworks, such as Tomcat, Jersey, Django, Gunicorn, and Flask, can be used for this purpose.

Virtualization

To make your server services independent, consider using virtualization tools like VirtualBox, Docker, or Kubernetes

User manuals

Providing users with the option to access application details can be beneficial.

Excel macros

Using Excel macros, you can automate various tasks associated with data processing and presentation

Benefits of having a personal project

In a personal project, you set the goals and, if working alone, take on all development roles.

Learning by trial and error
As the creator, you are responsible for ideating features, designing them, and developing the final product
You can share your project while demonstrating your skills at the same time
This allows for the development of skills across various roles

Testimonies

"The ChessPdfBrowser application is appealing for chess players with PDF chess books that lack available games in a PGN format."
Fran Rojas

"The integration of artificial intelligence in face recognition enhances the appeal of the Morphing Video Editor application."
Fran Rojas

"The capabilities of artificial intelligence have been a valuable asset. Thanks to it, I was able to innovate in the implementation of the IEEE article on fractal image compression by using K-medoids to select the most representative triangles for the codebook."
Fran Rojas

"Using generic classes in the application to calculate a polynomial's roots allows the algorithm to be programmed independently of the specific numeric type used."
