MIT App Inventor is a visual programming environment that enables everyone to build apps for smartphones and tablets. The course for beginners does not require any previous programming experience. It starts with an introduction to the App Inventor interface. Then, after Event-Driven Programming is explained, learners will discover the available command blocks which they will have to combine to make their own apps. During this course, learners will have the opportunity to use their imagination and practise analytical and critical thinking to create their own apps such as animations, games, quizzes, tourist guides or drawing apps. This course also aims to engage intermediate or even advanced App Inventor programmers who can build on their previous experience to create more sophisticated apps. The content and pace of the course is adapted to the age and needs of the learners.

We will be using MIT App Inventor. It is a visual programming environment that enables to make apps for Android smartphones and tablets and is a very motivating tool for engaging learners with computing. A visual "building block" method of programming is utilized in MIT App Inventor and it is incredibly easy to master. There is no need to have any programming experience. I will adapt the content of the course to the age and wishes of the learners. I also teach foreign languages and make learning apps. I can also teach you how to do that.

Computer programming is the craft of writing useful, maintainable, and extensible source code which can be interpreted or compiled by a computing system to perform a meaningful task. I have 7 years experience in computer programing. Together we will learn how to write the computer program from the beginning level. I can be your teacher in: Android Java MATLAB C#

You found an old file—something important, maybe even sentimental—but your computer just won’t open it. Or maybe you’re dealing with a custom software system that uses a weird, proprietary format. What now? I specialize in rescuing, translating, and reverse-engineering data formats that most people don’t even recognize. Whether it’s a corrupted calendar file from a PDA or a bizarre export from a dead program, I approach it like a digital archaeologist. It’s not magic—it’s patience, logic, and deep technical skill. If something should work but doesn’t, let me figure out why.
