Starting from my school days, including my time spent at university, I've participated in many programming Olympiads.

· In my last year at university, I won a silver medal in the Republic Olympiad.
· In 2003, I traveled to the US and participated in IOI (International Olympiad in Informatics) as one of four participants representing Kazakhstan.
· From 2005 to 2010, I participated in a number of ACM ICPC competitions.

I developed an Android application to make interactive, adaptive tests to students on various subjects. It uses an internal SQLite database full of test questions.

The project was implemented using three different prototypes. The first was a simple test with no adaptivity. The second separated the questions into ten different levels and the user needed to answer at least eight correct questions to pass to next level. The third and final one was built with an adaptive approach in mind so a user who answers more questions rapidly increases his progress, otherwise, the progress slows down.

This project was implemented as part of my PhD research.

I built this Python-based application to assign specific seat arrangements in an auditorium during university exams. It uses students' registration details as input to obtain a list of relevant students and their registered courses.

A manager inputs the exam dates and the specific auditoriums along with their capacities. The application then chooses the auditoriums for each exam and assigns each student a specific seat. It also creates an Excel spreadsheet with a different student seating plan for each exam and their exact seat assignment.

This generates a mosaic image using a set of grayscale images. I used a PIL library in Python to extract information from the images and reconstructed larger images using pixel data and selecting an image that is closer in the color space to each given pixel. As a result, some very large images that were created consisted of other images.

This is a Java project that I used in my class called Introduction to Algorithms. I used it to detect plagiarism in my students' source code. It took all of the student-submitted source code, compared it to one another, and similar programs were detected. This project preprocesses all of the source code and removes unnecessary information such as comments and extra spaces, leaving just the variables, and then compares the code.

I worked as part of the team that implemented a document management system for a small company using a Joomla framework on PHP. I specifically implemented the version reconstruction of the document that was sent, redirected, returned, and updated by multiple people.
