About Me

I’m Hüseyin Aydın, a Senior Backend Developer based in Istanbul, Turkey. I specialize in Java and Spring Framework, building scalable, high-performance systems using microservice architectures and event-driven design.

Over the years, I’ve worked on FinTech, E-commerce, and Investment platforms, focusing on margin trading systems, real-time order management, and asynchronous data processing. My passion lies in designing resilient backend architectures that scale effortlessly across distributed environments.

I have hands-on experience with Kafka, Redis, Docker, Kubernetes, and AWS Cloud, and I often combine these with observability stacks like Prometheus, Grafana, and New Relic to ensure performance and reliability.

Beyond backend engineering, I enjoy experimenting with frontend technologies like React.js to understand the full flow from UI to database.
