Nazarbek Amanbek

I’m a backend-focused Go developer with 1.5+ years of hands-on experience and a completed backend internship at Astana Hub. As a 3rd-year Software Engineering student at Astana IT University, I focus on building reliable services that perform well in real-world conditions.

I’ve delivered practical backend improvements, including a 3x database speedup and a 5x report-generation speedup on a production CRM system. I build REST and gRPC services using goroutines, channels, and context-based concurrency—grounded in unit testing and maintainable patterns like table-driven tests.

During my Go Developer work on ticket management, I implemented JWT authentication, logging middleware, panic recovery, and graceful shutdown. I also optimized PostgreSQL with composite indexes and pagination, reducing average response time from 300ms to 90ms.

I’m especially motivated by systems that are both fast and observable. I built a highload URL shortener with full Prometheus/Grafana monitoring and alerting, and I enjoy designing concurrent solutions such as a worker-pool job vacancy parser and a WebSocket + Redis Pub/Sub real-time chat.
