Projects

Production-grade systems built with distributed architecture thinking. Not demos — real engineering case studies.

Featured Project

Distributed Real-Time
Trading Platform

Event-driven microservices for real-time order matching. Apache Kafka as the central event bus, Spring Boot microservices, in-memory priority queues for order matching, and Kubernetes for production orchestration.

GitHub

Production-grade distributed trading platform built on event-driven microservices. Apache Kafka as the central event bus ensures reliable message delivery and fully decoupled service communication with guaranteed ordering per symbol partition.
