A techno-obsessive being who occasionally scribbles on paper, deals with the development thing. Software Development Engineer at @sahibindencom

Software Development Engineer with 8 years of experience specializing in distributed systems and scalability. Currently working as Principal Engineer in the Search Team at Sahibinden.com, leading high-impact projects including Conversational Search with Google Gemini integration, Vector Search, and AI-powered search experiences. I have extensive expertise in Elasticsearch, Generative AI integrations, Real-Time Bidding infrastructures, and building scalable microservices with Java Spring Boot. I architect and implement distributed systems from scratch, with proven experience in horizontal scaling, load balancing, database sharding, and event-driven architectures. I establish comprehensive observability stacks using Graylog and Grafana, define SLOs, and implement automated monitoring systems. My work spans full-stack development using Angular and TypeScript, big data processing with Apache Spark, and WebSocket-based real-time communication systems. I actively engage in technical leadership, mentoring team members, code reviews, and architectural decision-making. I focus on code quality, system reliability, and the migration of legacy systems to modern architectures. I hold a Bachelor's Degree in Computer Science from Dokuz Eylül University with a GPA of 3.62/4.00, graduating as Department Valedictorian.
