An integral part of this particular vocational sector is that it evolves faster than any other. As a result, I make sure not to stick to a particular technology, and to widen my knowledge, so that I am always ready to be standing next to state of the art technology.

As a result, my current niche lies with the MERN stack development. NoSQL database languages are gaining ground nowadays, so MongoDB is my preference. Also, the ability to write both back- and front-end in javascript, along with the multiple packages offered, make NodeJS a no-questioner. However, I'm also using the classic technologies, like Java, MySQL and PHP since the web nowadays comprises mostly of them.

As far as front-end is concerned, the emergence of javascript templates rules the web, so VueJs, ReactJS and AngularJs are what I prefer to use. Of course, none of the above would be possible without HTML5, CSS3 and pure Javascript (or some jQuery). To make powerful, dynamic web applications, I prefer to use ReactJs, exploiting the advantage of React Native to turn web into mobile applications without changing tools.

Being passionate about whatever makes people's lives easier and living by the standards of professionalism, I am for sure the best candidate to develop your software. Every project is special to me, and you will not ever doubt that I am paying the right amount of attention to your needs.

Feel free to contact me about your project and I will be more than happy to discuss your needs with you.
