Using Resilience4J, this is a Demo project which uses a Library as background and manages all its requests. This library can rent books online and the usage rate is extremely high. There is a reactive way to access, which is the one normally used, but sometimes, the system needs a bit of help from an old machine running a non-reactive MVC Spring application using JPA. Let's make this in Kotlin and find the best solution!

news-cast-explorer

The goal of this repository is to create a tool which users can install as a service and with that, have their phishing emails automatically sent to whatever user map them to. I will only make an official release of this when I'm absolutely sure of a couple of things. One is that the wrong mail doesn't get emailed to a phishing reporting service and make sure that to the best of my knowledge, the phishing emails are reported by the minute you receive them. This will give pirates and hackers a lot less time be able to escape. All of this comfortably knowing that no script will be run from the emails received.

image-train-filters-web

This is an Image transformation webservice where we can see 3 algorithms performing updates on images. It implements a contour for images, the Kuwahara blur filter and finally an algorithm I made myself called chartizate. The latter creates images where the foreground is written text.

Implements most common used methods for image comparison with the goal of making a case study between the different proposed algorithms

Worldwide, the ISBN number is used. It is a massive collection of numbers which uniquely identify books per type and edition. Based on that, this project is here to evaluate the recent experimental project from the spring team called Spring-FU. As DSL that, when released, it will allow Spring applications to be developed without the use of annotations. The main argument is that annotations bring unnecessary overhead to the application and that processing time can be avoided.

A note manager application that implements a search engine for story telling texts. It feeds a UI and the idea is to show how can we, with Arrow, use its benefits to create a more robust, resilient, back-pressure resistent, innovative application with support for high capacity and high availability.

This project is a performance study of how REGEX can work better or worse considering different cases. It is called string array paradigms because it actually studies Strings and Arrays in a very deep level.
