Since I started to learn software coding in Delphi and I am always looking to learn new languages, I discovered in VB an easy and well object oriented language. My experiences was making Windows services, desktop applications, user controls, websites and web services. In the mobile my experience was with Windows Mobile in warehouse and point of sales, also in some applications used by companies to control stock or production with RFID.

For some projects and with previous C++ knowledge's from the university, I started to use C# so many years ago as one of my favorite languages. As VB.NET I have many projects done and with years of success, mostly in lottery applications. My experience with c# include some mobile apps developed using Xamarin.

Along with develop of websites the use of client side code its very important to get sites running smooth and fast. I have many years working with Javascript and its tools, using it for validate, conversions, change of behavior, drawing and more.

I have many years of experience developing websites using styles also mentoring part of the team with the markup language and the user experience, so I can help in the design and code process.

I made two applications for the iOS some years ago in Mono project before the creation of Xamarin, later with Xamarin I made a few more mobile applications for Android. Some of this can be found in the Play Store.

As database is the base of storing and retrieving of the information which is vital part of the applications, I have years of experience of the design and use of SQL databases like queries, SP and its calls or executions from the .NET libraries.

For some projects I was able to learn and develop applications that makes use of Oracle databases, using the PL/SQL, Triggers and procedures.
