More than 15 years working in the field of software development.
Automation of the company s activities based on 1C: Enterprise.
Setting up and administering standard and atypical configurations based on
1C.Drawing up instructions and technical documentation for the created software
product.Modification of configurations.Development of configurations for the
tasks of the company.Integration of 1C with external systems.Work with trade
equipment (scales, barcode scanner, acquiring).Development of a motivation
system for sellers, managers.Development of systems for planning orders and
distribution of goods between branches.Development of warehouse logistics
systems accounting of goods, cellular warehouse, automation of inventories.
Development of web services.
Knowledge of the processes of activities of organizations wholesale and retail
trade, CRM, manufacturing, finance, personnel, accounting.
Experience in MS
SQL server administration ability to configure archiving, optimize databases.
Experience in writing technical instructions.
Since childhood, I was interested in programming, and when I studied at the
university, I got the opportunity to study 1C as a trainee in one company in
Minsk. For several months I studied and did the simplest routine work, then I
passed the exam at the 1C company, and start working. Since that time, I have
constantly worked with 1C in various companies in Belarus and Russia.
After moving to Lithuania, I continued to work with 1C remotely. Mostly as a
freelancer.
At times I had to solve problems using different programming languages (PHP,
Visual Basic, Python, SQL), but these were one-time relatively simple tasks.
At one time there was an attempt to switch to SAP, but it was difficult to
combine education with work, in the end I abandoned this idea. Later, I tried to
get into mobile development, but I didn’t get to real projects. The situation was
similar with machine learning. However, I plan to return to study of AI and
mobile development later.
In 1C, in most cases, it is difficult to single out some outstanding project; in
most cases, this is a routine revision of configurations. The most interesting
projects for me were those that I started as my own business. Alone or with a
small team, I made an application for restaurants, small businesses and a
mobile application (this is also possible on 1C). Technically, they were all
completed, but they practically did not go to the market.

Client-side high-efficiency optimization for real-time location system. There was a problem with a huge amount of messages through WebSocket channel about positions of all trackable objects. After some small amount of objects it start to have some freeze on client side because of overload main ui thread. I've created WebWorker for handling WebSocket messages about their positions, collect it to hashmap to overrite deprecated one and pass to the main ui thread only fresh data constantly each 250ms. After this improvement starts to be able to track much much more objects during one floorplan.
