WORK EXPERIENCE

 AvMap Ukraine, Junior C++ Software developer
April 2023 - October 2025
Learned a lot new in C++ development, including Qt, Boost, CMake, OpenGL
etc. Developed new features in frontend using QML and in backend using Qt and
C++. Also, constructed many tests using GTest, worked with SQLite and
JavaScript. Was involved in creating new features from scratch and helped in
designing new flows. Took a big part in approving code requests by trainee
colleagues as well as teaching them about current projects. Working in Java,
 especially with Android development and Amazon Web Services is worthy of

Helped students of universities across the country to complete their course works
in C/C++ development, including writing apps (both back-end and UI) from
scratch. Solved different mathematic problems in Advanced Mathematics,
Probability Theory, Linear Algebra. Did re-factoring of program codes, including
QA testing. Lectured students in C++ development, mathematics and general
computer science.
 Various freelance jobs (not using any specific platform), program
developer
March 2020-February 2022
Started helping my classmates with their IT studies, writing tasks for them and
helping them to prepare for the exams. After entering university, started taking
