I am a dedicated and results-driven software engineer with over 5 years of experience in backend development, specializing in distributed systems and low-latency algorithms. My strong mathematical background and analytical problem-solving abilities have enabled me to consistently deliver scalable, efficient, and reliable solutions. I have a proven track record of building robust architectures and optimizing system performance, which has been recognized in my previous roles.

Throughout my career, I have worked on various projects, including a booking management system for hotels and a startup launching system with multiple microservices. My expertise in Java, Spring Boot, and event-driven architecture has allowed me to implement solutions that enhance flexibility and scalability. I am passionate about continuous improvement and have contributed significantly to software quality through integration testing and code reviews.
