As a Java backend engineer with around 4 years of hands-on experience, I excel in developing and operating end-to-end, high-availability web systems with a focus on achieving high performance and scalability. My expertise mostly lies in Java and Spring, and I have experience in object-oriented design, data structures, algorithms, and web services. My ambition is to continually learn and accumulate more experience and knowledge, which can help me transition into a decent solution architect down the line.
