Built a prototype of a bandwidth rate-limiting service within a telecom DPI platform. Implemented a concurrent hierarchical token-bucket (HTB) algorithm to allocate bandwidth across nested policies. Packet forwarder and analyzer: x2.3 throughput via multi-queue parallelism, zero kernel drops. Systems depth: TCP/IP, NAT, Linux process management, traffic analysis (Wireshark/tcpdump)

Проекты

Rate Limiter Service

Built a distributed rate-limiting REST service in Java with Spring Boot, backed by Redis for shared state across instances. Implemented token-bucket logic with atomic Redis operations (Lua) for correctness under concurrent load. Tools Used: Java, Spring Boot, Redis, Maven, JUnit

Packet forwarder

Built a zero-loss network monitor sustaining 10 Gbps / 1.25M pps (2.3× parallelism (PACKET_FANOUT) and GC-pressure reduction (sync.Pool). Tools Used: Go, Linux AF_PACKET, REST/JSON, concurrency, HyperLogLog

Chirpy - HTTP Server

Built a RESTful HTTP server in Go that uses JWT for authentication with refresh tokens, password hashing with Argon2id, and PostgreSQL database integration for user and content management. Tools Used: Go, PostgreSQL, JWT, sqlc, Argon2id
