● Key roles – product and technical elaboration of projects, resource planning, ensuring everything is in place to meet goals, metrics-driven development.Advertising Quality Department- spearheaded the technical and product evolution of the smart banners advertising product- identified and resolved several complex technical issues scattered throughout the product that had severely hindered its growth for years- justified the necessity, launched, and continued to improve new modern advertising formats- all of the above resulted in a six-fold increase in the product’s revenue (up to +200% YoY), and expanded its share in the Yandex Advertising Network from 3% to 11%- analyzed, fixed and enhanced the schemes for obtaining search advertising for partners, resulting in a 15-20% increase in search advertising revenue in each caseApplication Performance Service (Yandex Browser Ecosystem)- managed the acceleration and unification of various applications, achieving a 1% increase in market share of the Yandex search app on Android, 20% faster startup and 25% faster new tab opening in the desktop Yandex Browser, 20% faster search bar load and 60% faster SSO and redirects on dzen.ru- managed the extension of Yandex Browser support for Windows 7/8.x, maintaining compatibility after Chromium support ended, resulting in sustained user satisfaction and retention- established product vision, defined requirements and constraints for DivKit Pro (admin panel + visual constructor for full screens), collaborating with the designer to ensure optimal user experience

● Key role – Senior / Lead Game Designer of "Evolution 2: Battle for Utopia".- developed game loops, player progression, and the project's economic model (including monetization elements) in collaboration with the executive producer, ensuring cohesive and engaging gameplay- designed game systems and their interactions, prototyped algorithms to ensure seamless experiences and manageable outcomes, while providing flexibility for future expansions - led the entire lifecycle of features from concept and documentation to implementation and fine-tuning, managed the project's feature list- maintained game balance of progression and economic systems throughout project development- monitored project metrics, analyzed feedback and statistics for continuous improvement of the gaming experience, following a metrics-driven development approach

● Key role – game mechanics designer of "World of Speed".- analyzed and documented previously implemented vehicle acceleration and movement algorithms from the game's source code for subsequent improvements- enhanced core gameplay by integrating and tuning various game mechanics (including off-road behavior, weather-affected driving, drifting, and skidding) and fine-tuning vehicle dynamics to ensure their key characteristics matched the manufacturers' specifications- received positive feedback from colleagues and users (all aspects of vehicle behavior and physics were significantly improved; in QA's words, “we got the most out of the game engine”)- designed and balanced a vehicle performance upgrade system- developed a new system for distributing tracks and weather conditions in matchmaking, minimizing their repetitiveness for each player involved in the race- developed a user-friendly game design tool for quick tuning of a large number of different vehicle parameters, achieving partial automation and significantly reducing manual adjustment time

- led a development team of 4 technical specialists, organizing the development process and coordinating team activities (including task management and sprint planning)- communicated with clients to ensure effective prioritization and timely project delivery- designed DWH architecture, constructed data warehouses and data marts for several banks- developed complex and efficient algorithms to meet functionality and performance requirements, resolving key technical and architectural challengesProgramming languages and technologies used: SQL, Oracle, Greenplum, ODI 11g, Informatica, Jira

- improved existing web applications (both back-end and front-end), identifying and fixing numerous bugs and vulnerabilities, and refactoring the source code- solved various tasks to maintain the functionality of the holding’s IT infrastructure- developed comprehensive cross-browser, cross-platform interface and functionality tests for existing web applicationsProgramming languages used: Python, Ruby, JavaScript

- extracted, transformed, and loaded banking data to develop data marts and data warehousesProgramming languages and technologies used: SQL, Python, Oracle, Informatica, etc.

● RoadMonitor project (processing of road surface depth maps and images for flaw detection)- developed an algorithm for 3D model reconstruction from LIDAR data, as well as project-specific algorithms for 3D model processing and filtering- developed an edge detection algorithm leveraging 3D model and LIDAR data, as well as tools for visualization and interaction with the model● LidarK project (open-source framework for processing multidimensional data)- redesigned the algorithm of adding points to Seg-Tree (a variation of R-tree)- developed an algorithm for interactive segmentation of 3D point cloud data, as well as a corresponding visual tool for interaction- co-authored the paper «Robust LIDAR data segmentation using compact point clusters»Programming languages used: C/C++, MATLAB
