CV
Behind the character is an ambivert, I have strategic and critical thinking, I do not like to sit still, if there is no work, then I come up with it myself.
From the very youth I was interested in electronics, repaired various household appliances, decided to study as a programmer, which I do not regret a bit and I have a desire to further develop in this specialty.
Having continued my studies already as a computer engineer, I really wanted to get a deep knowledge of how computers and all electronics work at the physical level, and I got exhaustive knowledge in this.

180 USD Power outage schedule
Hybrid Mobile Apps
Project to develop a program for the schedule of power outages.
The main functionality of the program includes the following features:
1. Area selection: The user can select an area from a list downloaded from the Internet.
… 2. Show outage schedule: After selecting a house number, the program displays the group of that address and the outage schedule per week.
The program works on the basis of using the Flutter framework, which allows to create cross-platform applications for different operating systems. It provides a consistent interface across platforms (Windows, Web, Android, iOS, MacOS, Linux) and the use of Material Design 3.
The program uses external resources that provide information on power outage schedules. Thanks to this, the user can quickly and conveniently receive up-to-date information about the disconnection in a particular locality.

135 USD Modular robotic camera control platform
Desktop Apps
Development of a modular software platform for controlling the robo-camera.
The robo-camera consists of a cylindrical coordinate system manipulator, an Arduino UNO control board, and an OV7670 camera with an Arduino NANO control board.
Both control boards are connected to the computer via the USB interface using the Serial protocol.
The idea is to develop a platform (API) that allows you to abstract from the data exchange protocols between the plugin and the robo-camera, the plugin implements some functionality, for example: manual control of the robo-camera, searching for a face in the image and following it, etc.
…
Program functionality:
- Responsive and adaptive modern design;
- functional connection / disconnection from the robo-camera and handling of all related errors;
- the system automatically loads all available plugins from the file system and displays them;
- implemented floating camera widget that allows you to see the image on any selected plugin;
- connection setup and plugin activation/deactivation.
Implemented built-in plugins:
- manual control of the robo-camera, control is carried out using the keyboard;
- control using machine vision, finding a face in the image and following it.
Stack:
- Gtk4 and components Adwaita, Gio, GDK, GObject, GLib;
-Python3;
- OpenCV, PySerial, logging, Cairo, numpy;
- CSS;
- Linux, PyCharm, Gnome Builder, Cambalache, Glade.

Development of NFC lock on Arduino and Android application
Freelancer Vadim formulate the TZ, created the design – although it was not required, he in advance to find problems that were not visible at first. Discovered in all the subtilities of the project. I had a task above my expectations. To my surprise, Vadim approached the implementation of the project as serious as possible, if to say otherwise, then "as to his own." According to Vadim’s work, it is clear that it’s not a job for him, but a complete pleasure, because the approach to the execution of the project on the face, as to the favorite thing. In general, I am very pleased with the collaboration with Vadim and I recommend it to all, you will not regret it.
