Backend engineer specializing in scalable systems and cloud technologies.
TurkeyWhat I'm looking for
I am a dedicated Backend Engineer with a passion for building scalable and efficient systems. Currently, I am working at PLUSMINUSONE, where I architect and optimize backend services for applications that serve millions of users globally. My expertise in AWS, TypeScript, Node.js, and various database technologies has enabled me to drive significant improvements in system performance and reliability.
Throughout my career, I have successfully led initiatives that resulted in substantial operational cost savings and enhanced system efficiency. For instance, I eliminated polling delays by migrating to a queue-based architecture, which increased throughput by 10-15% under high load. My commitment to quality is reflected in my rigorous testing practices, where I have implemented comprehensive integration and end-to-end tests that have improved system reliability. I am always eager to adopt new technologies and methodologies that can further enhance the performance and maintainability of the systems I work on.
