India

I am a trainer by profession. Currently I am working with iFuture Technologies(India) as a Senior Faculty. I enjoy programming as a hobby. During my career I have seen the growth and decline of many technologies, many of them being my favorites like Flash, WPF, Windows Mobile Development. Few of my current favorites are Android, Xamarin and Python, though I also like traditional and evergreen languages like PHP, C#, Visual Basic and Java.

Apart from computers, my favorite pastime is bicycling.

I am a software architect and a developer with great passion for new engineering solutions and finding and applying design patterns.

I am passionate about learning new ways of building software and sharing my knowledge with others.

I worked with many various languages including C#, Java and C++.

I fell in love with WPF (and later Silverlight) at first sight. After Microsoft killed Silverlight, I was distraught until I found Avalonia - a great multiplatform package for building UI on Windows, Linux, Mac as well as within browsers (using WASM) and for mobile platforms.

I have my Ph.D. from RPI.

Paulo Zemek

Software Developer (Senior) Microsoft

United States

I started to program computers when I was 11 years old, as a hobbyist, programming in AMOS Basic and Blitz Basic for Amiga.
At 12 I had my first try with assembler, but it was too difficult at the time. Then, in the same year, I learned C and, after learning C, I was finally able to learn assembler (for Motorola 680x0).
Not sure, but probably between 12 and 13, I started to learn C++. I always programmed "in an object oriented way", but using function pointers instead of virtual methods.

At 15 I started to learn Pascal at school and to use Delphi. At 16 I started my first internship (using Delphi). At 18 I started to work professionally using C++ and since then I've developed my programming skills as a professional developer in C++ and C#, generally creating libraries that help other developers do their work easier, faster and with less errors.
