With over 5 years of experience in building high-performance, scalable backend systems using Java, I excel in designing robust solutions with Spring Boot and microservices architectures. My expertise includes multithreading, concurrent programming, and optimizing systems for low latency and high availability. I am proficient in RESTful APIs, SOAP services, and message queues (e.g., Kafka), and skilled in both relational (PostgreSQL) and NoSQL (MongoDB) databases. My experience extends to cloud platforms like AWS, Docker, and Kubernetes, where I deploy and scale cloud-native applications effectively. I apply Domain-Driven Design (DDD) to create fault-tolerant systems and adhere to software engineering principles such as OOP, SOLID, and TDD for maintainable code. Additionally, I have hands-on experience with CI/CD pipelines and Agile methodologies, driving technical innovation and leading teams to deliver impactful solutions.
