DSS system Opti-Wood is designed for wood harvesting enterprises as a production optimization tool for planning, management, and control. The system has a digital map-based GIS tool to improve the visibility of planning results. The largest Russian pulp and paper industry company was one of the customers. I was the lead developer and system architect. I designed math optimization models, implemented algorithms with most back-end logic, and created an Android application for factory management.

A cloud-based service designed as a tool to optimize production for companies that are engaged in stone processing. I served as a lead back-end programmer and project architect and handled math modeling and implementation of optimization algorithms.

Cadaster is a web application created by a team led by me for calculating the mass cadastral valuation of real estate objects. It uses various statistical methods to calculate mass cadastral valuation based on numerous factors, including territorial ones. For them, a GIS map was created based on the OpenLayers library.

Repair is a microservices-based application related to processing sensor signals to predict machines' breakdowns and parts in factories. A team of 15 people developed it: four of them, including me, were in charge of REST APIs to CRUD signal data, obtaining online data via WebSockets paired with a message broker, and developing a UI to visualize various signal characteristics.

Represents development of taxi automation system. From my side, the following features were implemented: a client notification service (SMS/calls), binding for PBX Asterisk, a web application to view the KPIs of the taxi service, and an Android application to order a taxi.

An optimization algorithms library for solving different manufacturing tasks by projecting math models solved using linear programming, non-linear programming, dynamic programming, heuristic programming, and meta-heuristic programming. My role was to implement most of the optimization methods from the computer science parts above.

A Jakarta EE application related to receiving, handling, and storing messages from various sensors in a big equipment chain using Apache ActiveMQ. I designed and wrote a data handling interface to get data from a broker and save it into a Hadoop database.

URobot Cloud is a cloud-based microservices application for managing robots, maps, and building models. It allows you to perform work at construction sites, enterprises, and factories using robots. I was a senior back-end developer and was in charge of the development of microservices with the main features of the application and improving performance.
