Developed game balance import system, which resulted in fully automated game design updates. Designed and implemented user's save migration subsystem for simple applying game version updates.

Increased overall application performance about 3-5% using proper data structures and optimizing bottlenecks. Developed time-limited game events system, which resulted in higher money conversion. Implemented game protection from time-cheating threats based on system's steady clock. Refactored critical parts of supported game projects with legacy code, resulted in easier further maintenance.

Developed client / server network application with p2p communications for embedded devices connected via mobile broadband (with ability to transfer large file using torrent-like approach). Developed SIP audio intercepting application for high load of simultaneous calls (libpcap, Boost.Interprocess). Designed and implemented database and API for Uber-like application (Django, Redis, PostgreSQL).

Designed and developed custom Wifi captive portal (server and embedded clients as gateways), which provided seamless client network roaming using MAC authorization (Linux, OpenWRT). Implemented C++ monitoring solution for video streaming nodes, which resulted in reduced outages by 30%.

Implemented software for cryptographic hardware tokens and client / server communication layer according to Ukraine national standards on information security, which allowed the project to process sensitive personal data.
