Hi, I'm Aleksandr Beljakov. I design highly resilient, high-concurrency systems for the complex demands of modern Gaming & Gambling platforms. From architecting high-throughput sportsbooks and real-time betting engines at betPawa and pawaTech, to scaling global matchmaking networks (30M+ DB scale, 1M active users), I engineer robust, low-latency microservice architectures that deliver 99.99% system availability.
How I approach high-scale systems development
Specializing in sportsbook architectures, betting transaction cores, stateful real-time game engines, and low-latency validation systems. Leading publishing pipelines and engineering core registries as a board member of BSBS GAMES OÜ.
Designing highly decoupled, resilient microservices fleets using Java and Spring Boot. Leveraging high-speed gRPC streams to establish strongly-typed binary service contracts, eliminating API gate overheads.
Decoupling high-velocity betting and matchmaking transaction pipelines using Apache Kafka and RabbitMQ. Engineering bulletproof queuing patterns to ensure transaction isolation, eventual consistency, and zero-loss operations under load spikes.
Scaling databases using certified TiDB NewSQL and MySQL configurations. Specializing in horizontal scaling, multi-region replication, and query routing to achieve continuous operational availability.
Provisioning, deploying, and scaling microservices globally using Kubernetes and Docker. Managing infrastructure-as-code to build self-healing auto-scaling clusters that guarantee 99.99% system availability under intense user loads.
Real-world systems engineered to scale
Scaled core sportsbook software engineering fleets to support 5M+ active bettors. Engineered an ultra-fast, event-driven settlement engine capable of processing and settling 3M+ bets in tight windows with absolute transactional isolation using gRPC, Kubernetes, and Apache Kafka.
Designed and implemented a high-concurrency matching engine utilized across 37+ countries. Engineered real-time matchmaking queues, low-latency candidate searches, and real-time state synchronization, handling 30 million registered users in the database with up to 1 million active users.
Certified in TiDB for MySQL Users (MySQL-specific features). Engineered and configured horizontally scalable NewSQL databases to maintain ACID compliance globally while providing continuous uptime and real-time analytical capabilities under extreme read-write scenarios.
Designed, developed, and deployed high-performance game architectures as an independent lead. Orchestrated complete pipelines: from core game mechanics and network synchronization engines to automated cloud staging, self-healing Docker hosting, and continuous liveops monitoring.
