Listing Java without specifying the version
State the Java version (e.g., Java 17, Java 21) to show you work with modern language features.
Not mentioning system scale or performance metrics
Include transactions per second, latency targets, uptime SLAs, and data volumes you handled.
Omitting testing practices
Mention code coverage percentages, testing frameworks (JUnit, Mockito), and TDD practices.
Ignoring migration and modernization experience
Monolith-to-microservice migrations are highly valued. Describe the scope and outcome of any migration projects.
Java Developer Resume FAQs
Which Java certifications are most valued?
Oracle Certified Professional (OCP) for Java SE is the most recognized. AWS or Azure certifications complement it well for cloud-focused roles.
Should I list both Java and Kotlin on my resume?
Yes, if you have experience with both. Many companies use Kotlin alongside Java, especially for Android or Spring-based projects.
How do I show microservices experience?
Describe the number of services, communication patterns (REST, Kafka, gRPC), and the scale at which they operate.
Is Spring Boot experience mandatory for Java roles?
For most backend Java roles, yes. Spring Boot is the dominant framework. Also mention Spring Cloud, Spring Security, and Spring Data if applicable.
How important is system design knowledge?
Very important for senior roles. Mention distributed systems concepts, caching strategies, and scalability patterns you have implemented.
