Hi, I’m Ankush — a Java Backend Developer with 2.5+ years of experience building scalable, cloud-native applications. I bring 1000+ hours of hands-on coding and DSA practice, along with strong expertise in Java, Spring Boot, Spring MVC, Hibernate, JPA, RESTful APIs, and MySQL, with working knowledge of HTML5 and CSS3. I have experience designing high-traffic backend systems, integrating payment gateways, and building event-driven architectures. I’m passionate about clean code, performance optimization, and developing resilient, low-latency services that scale reliably in production. I enjoy working on challenging projects, continuously learning new technologies, and adapting easily to both remote and on-site environments.
