Artem Kostritsa

Developed and architected multiple ecosystem products with a focus on Playdeck, a central hub for game discovery, engagement, in-app payments, and community interaction. Addressed key challenges such as scalability and performance by implementing auto-scaling and load balancing to efficiently handle traffic spikes. Ensured security through encryption, secure authentication, and regular audits. Designed a microservices architecture including services for bot, game catalog, user profiles, leaderboards, payments, and push notifications. Optimized data access using Redis for read-heavy operations and leveraging Redis queues for delayed task processing. Integrated Playdeck seamlessly with other ecosystem products, enhancing user profiles, social features, in-game purchases, and cross-platform gaming experiences.

Played a key role in the development and launch of a startup product enabling seamless integration of in-app social feeds with minimal code. Led development and architectural design of the core functionality. Focused on customer satisfaction and efficient development processes while integrating the SDK with three applications. Spearheaded the launch of Angelboard, a fundraising community built on Tribally, powered by Ethereum blockchain with Solidity smart contracts and Web3j. Responsible for system design and implementation leveraging blockchain technologies to create a decentralized and transparent platform for content creators and supporters.

Developed and optimized a Demand-Side Platform requiring a high-performance, scalable, and event-driven architecture for real-time bidding (RTB) and large-scale data processing. Addressed challenges in scalability and performance by designing high-throughput systems using RxJava and Kafka for real-time event processing. Optimized MySQL and Druid for fast analytical queries on large datasets. Implemented Aerospike caching for frequently accessed data, reducing response times. Built modular Spring-based microservices for efficiency and maintainability. Ensured millisecond-level response times for programmatic ad auctions.
