Top SchoolCengizhan Çalışkan is a Staff Software Engineer with 11 years of experience building high-performance, cloud-native microservices across startups and enterprise teams. He specializes in Go and Python for scalable, low-latency systems, with strong hands-on expertise in Kafka, PostgreSQL, Elasticsearch/OpenSearch, and containerized deployments on AWS and GCP. His work spans search and recommendation systems, event-sourced distributed architectures, and production ML serving—often delivering sub-300ms services and decomposing monoliths into resilient microservices.
