Due to a non-disclosure agreement, I am limited in sharing detailed specifics about my current project.● Provide mentorship and conduct code reviews for junior team members● Engineer a client-server application (game) using .NET & C++● Author RFC documents to propose and clarify new feature implementations● Develop source generators and custom Roslyn diagnostics, identifying and resolving potential bugs, contributing to the software's reliability● Write unit and integration tests to maintain a high-quality codebase, ensuring reliability of the application.● Integrate the 'Sony NP' online service API, facilitating the project's launch on PS4 and PS5 platforms

● Engineered a backend solution utilizing .NET Core and PostgreSQL, focusing on user state management. This enhancement notably amplified system stability and scalability● Contributed to the development of a backend leaderboard service by employing Go● Decreased the server's CPU load by optimizing AI implementation, thereby enhancing system performance by 5%● Led the development and implementation of key server-side features, including: hero mechanics, new game modes, Utility AI, and pathfinding algorithms.

● Engineered a distributed actor system to optimize user state management, utilizing a tech stack comprising .NET, PostgreSQL, and Redis.● Developed a wide range of server-side features including: matchmaking, items, leaderboards, bounty chests, player's inventory● Implemented a dynamic backend for the admin panel using ASP.NET, facilitating efficient live operational management● Integrated an analytics platform employing Kafka & C#, enabling monitoring and detailed analysis of user statistics● Conducted load testing to ensure reliability under peak loads which helped to support over 20,000 concurrent users.● Significantly improved the median server response time by 15% through optimization, focusing on reducing garbage collection (GC) pauses, minimizing memory traffic, and eradicating memory leaks, thereby enhancing overall system responsiveness.

● Engineered a new version of the backend server for a major web resource, significantly boosting its capacity to handle concurrent users.● Incorporated multiple third-party services such as booking system and schedule parsing, enriching the platform's functionality and contributing to a notable increase in revenue● Executed code reviews, minimizing bug occurrence and facilitating the seamless integration of new features● Rolled out an integration with ElasticSearch to introduce search features, enhancing user engagement and interactivity on the platform

● Engineered core features using ASP.NET MVC, enabling clients to make informed product selections based on multiple criteria, which increased revenue by 24%● Optimized database performance by analyzing and restructuring SQL queries, creating indexes in MSSQL, and rewriting hot-paths. This enhancement boosted the system's capacity to handle more concurrent users and reduced spending on servers due to improved efficiency● Enhanced website loading speed by 40% by restructuring HTTP routes, leveraging insights from dotTrace profiling, significantly improving user experience and engagement
