Sercan Ayyildiz is a Senior Software Engineer with over 8 years of experience building and operating distributed, high-throughput systems using Java, .NET, Python and cloud-native technologies. He has deep practical expertise in machine learning engineering and data pipelines—having developed an online ML module with incremental learning, partitioned streaming and model versioning for a multi-node decision platform—and has integrated custom algorithms and external model services. Sercan combines systems-level skills (Cassandra, Docker, Linux, AWS) with strong test-driven practices (TDD/BDD) and a background in computer vision (OpenCV) used in production ID-document projects. He has driven coding standards, prototyped resilience tests via a chaos engineering tool, and taken on technical lead responsibilities including DevOps, security audit readiness and hiring. Based in the Randstad, he’s comfortable moving between hands-on implementation and architectural leadership, often improving performance and reliability in legacy and cloud environments. An understated strength is his habit of inventing practical tooling (deployment and chaos tools) to validate and harden complex distributed services.
