Information system with a client-server architecture, written and maintained from scratch by myself alone.
The key functionality of the system includes managing the structure of the organization, the corporate phonebook, conducting tenders and contracts of the organization.
The server part of the system is an ASP.NET application with the service layer implemented with the WCF RIA Services technology.
As a data storage, a database under the control of MS SQL Server DBMS is used, the data access layer is implemented using the ORM Entity Framework. Database development is carried out according to the Model-first principle using the EDMX schema.
The client part of the system is a Silverlight application divided into separate modules that encapsulate the implementation of individual sections of the system. Dynamic loading of modules on demand is carried out using the Prism framework.

This information system is intended for planning meetings of the collegium, preparing materials for them, managing the workplaces of meeting members, as well as synchronously displaying meeting materials on the central screen of the meeting room and workplaces of meeting members.
The system is a software package that includes a service, a client web application and a native desktop application.
My work on the system is divided into two stages: as a contractor while working at Intelcom and as a stakeholder at CEAIT SP.
By the time I started working as part of a small development team, the system had been around for some time, so I had to start by looking at the existing source code.
In the course of work, the system was refactored, and then the components were rewritten using a more modern technology stack: replacing Silverlight with ASP. NET MVC, and Windows Forms with WPF.

Helpdesk-system with client-server architecture, written and maintained by myself alone from scratch.
The system is intended for registration and processing of requests to the technical support service of the Accounts Chamber users.
The server part of the system is an ASP. NET-application with implementation of the service layer using WCF RIA Services technology.
Database under the control of MS SQL Server is used as a data storage, data access layer is implemented using the Entity Framework ORM. Development of the database is done according to the Model-first principle by means of EDMX-scheme. The client part of the system is written in Silverlight.

The information system is designed to register the results of expertise of legal acts projects submitted to the Accounts Chamber of the Russian Federation.
The system is a program complex with client-server architecture. The client is a web application developed using ASP. NET MVC, which interacts with REST-service, that provides operation with the data stored in the database under the control of MS SQL Server DBMS.
The system includes several modules: a module for recording the results of expert review of draft laws and regulations, a module for integration with the interagency electronic document interchange system, a module for integration with the state financial control portal, and an analytical module for reporting.
My work on the system is divided into two stages: as a contractor during my work at Intelcom and as a customer at the FSI CEAIT SP.
I developed and implemented the first version of the system by myself, during the further evolution of the system I was in charge of a small team of two to three developers.

It is the key information system for automating the activities of the Accounts Chamber. The main features include the formation of an annual plan of activities (inspections) and control of its execution, preparation of materials for inspections, recording the results of their implementation, and report generation.
In this project I participated in the formulation of technical specifications for the system, was a member of the acceptance committee, participated in system tests, dealt with operational issues, developed solutions for problems faced by system users, reverse engineered the system because even its developer could not always say how it operates, made data extracts for analytical purposes.
The version of the system that was functioning at the time I joined the Accounts Chamber was developed using C++ Builder with an Oracle database and had a very high bus factor. After some time it was decided to modernize the system by transferring it to a more modern and import-independent technology stack: Java backend, client web application and PostgreSQL database.
In the process of modernizing the system, I participated in the formulation of requirements, engineering, system design, and testing of functional prototypes.

This information system is meant for publishing information on financial audit and control carried out by various levels of authorities.
In this project, I played the role of a stakeholder: I participated in compiling the technical specifications for the system, approved the project documentation, took part in designing the system user interface, and was also a member of the acceptance committee and participated in system testing.
In addition, I was involved in the roll-out process of the information system and participated in the legislative support of the system operation processes, ensured technical procedures of data exchange with other systems of the Accounts Chamber.

The information system was developed by myself in a very short period of time (less than three weeks). Further development and support of the system was carried out by a team of two people.
The purpose of the system is to generate analytical data on the key characteristics of the Accounts Chamber’s activities. The data of this system is also used to assess the efficiency of the Accounts Chamber inspectors.
Most of the data necessary for functioning is obtained through integration with other information systems (the system " Control Activities Complex", the system of expertise of legal acts projects), as well as with the aggregator of the Accounts Chamber staff information (combines, deduplicates and checks the integrity of data from the HR system, telephone book and LDAP-directory), also written by me.
Technically, the system is an ASP. NET Core MVC with a PostgreSQL database.

This information system is used to register information about people with disabilities, publish information about the social support system for such people, and automate processes related to the realization of the disabled people’s rights.
My role in this project was to define the directions of the system development, participate in the formulation of technical specifications, testing, implementation and relevant regulatory support.
A major step was the creation of a service for registering and checking information about vehicles transporting people with disabilities, which made it possible to eliminate the need for disabled people and their relatives to receive paper “disabled person” signs for vehicles.

An information system designed to automate the processes of assigning social support measures, registering information about recipients of social support measures, and publishing information about the social security system of the Russian Federation.
My role in this project was to determine the directions of the system development, participate in the formulation of technical specifications, designing, testing, implementation and relevant regulatory support.
The key stage of the system development was the creation of a subsystem for the establishment and payment of social protection (support) measures. This subsystem makes it possible to automate the processes of processing citizens’ applications for support measures, obtaining information, verifying it and making decisions on the assignment of support measures. In addition, this subsystem is responsible for informing citizens about their rights to social support measures arising in the event of certain life events, such as the birth of a child or the onset of a certain age.

A simple BI-system for calculating and displaying analytical indicators based on the data loaded into it.
The key task of the system was to meet the needs of the management of the Ministry of Labour of the Russian Federation to regularly receive up-to-date information on the key performance indicators of social sector organizations.
I managed to develop the system in two weeks, and within another week I was able to prepare and approve the regulation for the system’s operation to ensure that it was filled with data.
Technically, the system is an application on ASP. NET Core MVC with a PostgreSQL database.

The “My Export” platform acts as a single entry point for exporters to receive state and commercial services.
The system’s portal provides access to an extensive catalog of services that can be applied for through a system’s unified account.
My role in this project is to build efficient processes of developing new features and refining existing ones.

A set of bots for World of Warcraft to automate various tedious game activities. All bots worked inside the HonorBuddy shell, which took care of most of the concerns related to the injection into the World of Warcraft game process.
Creating these bots was a non-trivial task: HonorBuddy supported a narrow subset of the .NET framework, there was almost no documentation, so I constantly had to reverse-engineer and write auxiliary addons for WoW in Lua for some tasks, and all this had to be done in a way that wouldn’t trigger WoW’s bot detection system.

Bot for managing inventory, character bank and guild bank

This bot would log on to each character from the configurable list and perform a number of actions: put extra ingredients and money into the guild bank or character bank depending on the settings, craft valuable items from the list with customizable limits, auction items, collect money from the post office for items sold and items returned from the auction, and a bunch of other little things.

Bot for training and catching battle pets

This bot could form a roster of battle pets from the general collection according to the settings, form effective teams of pets, conduct pet battles with the capability of specifying battle tactics for each family of pets using a self-written scripting language, catch pets that are not yet in the collection or of better quality than the existing ones.

Resource gathering bot

This bot was dedicated to farming resources according to a list set up in its settings. It received the location of resources from a self-written service that parsed data from the Wowhead game database. Having received the spawn points of the necessary objects, the bot built an optimal route and went to collect them. The collection continued until the timer expired or until reaching the limit on the number of resources collected.

Bot for simultaneous launching of multiple bots

HonorBuddy could only run one bot at a time (one mode of operation), so I had to write a bot that could switch from one mode to another depending on the game situation and set of conditions, effectively allowing multiple bots to run simultaneously.

A set of combat bots for different character classes

These bots were dedicated to efficient combat management. For each class, I programmed optimal skill rotation for different combat situations (one target, multiple targets, lots of targets, etc.), as well as special routines to handle complex combat situations ( battling other players, using skills to get out of different types of control, etc.).

Mods for Rimworld — colony simulation game by Ludeon Studios.
My mods are aimed at reducing micromanagement in the game, i. e. automating some game mechanics: automatic distribution of colony members to work shifts, assigning types of work depending on the abilities of each colonist, automatic selection of equipment depending on the characteristics of the colonists and external conditions, etc.
The creation of these mods required mastering the Unity game engine and the executable code injection mechanism.
Also, often there is no possibility to see the source code of a particular modification, compatibility with which must be ensured, so I have to reverse-engineer and decompile.

A personal website where I talk about myself, my career path and the most important projects for me. Technically it is an ASP. NET MVC application running in a Docker container.
