• I'm part of team which works on Yandex Maps - it's a web-maps service. My main scope of work is harvesting & processing various cartographic data - the result of that processing appears on maps and helps millions of people in their everyday lives. Because there are terabytes of data, map-reduce clusters are actively used for such processing.
• Examples of projects:
• Adding information about flats to maps data (tens of millions flats) - data mining & interpolation.
• Launching a pipeline to decode information from signboards of organizations (50K+ signboards in most popular zones).
• Adding personalized real-time data to organizations to show it on maps (60K+ RPS in peak).
• Key technologies: Python, C++17, MapReduce, Toloka, ClickHouse.

• The project was generating and reliably delivering events for betting services. I started as an individual contributor and finished as a tech lead of the project. It was a mix of the architecture tasks, mentoring my peers, working on the infrastructure and programming itself.
• Created a system which worked as a single point of access to random events (at-least-once delivery, RabbitMQ & PostgreSQL HA clusters, 10+ events consumers).
• Implemented tools for controlling processes of various games (UI, a user-space driver for hardware, business logic of a game), 10+ games were plugged as events' sources to the system, worked 24/7.
• Made a proper infrastructure for the project (IaC as the main concept, monitorings, backups, logs, alerts, CI/CD). It drastically decreased the amount of indcidents.
• Key technologies: C++14, Qt, PostgreSQL, RabbitMQ, Python, Ansible, Docker, ELK stack.

• The main project was developing a set of Windows applications for penetration testing of corporate
• networks for known vulnerabilites (ICMP/DNS tunneling, system scanning for sensitive information,
• firewall bypassing, screen recording, etc).
• Made a dozen of small apps.
• Created a single huge application which could check for all possible vulnerabilities.
• Key technologies: C++11, .NET, Windows.

• I worked on a static analyzer of C++ code.
• Greatly reduced amount of false positive errors (~50%) on open-source codebases
• for certain checks.
• Created a new check which detects an unreachable code.
• Key technologies: C++, Windows, Linux.
