Chanukya Polaki

I am a Senior Java Backend Developer with nearly 6 years of experience building and maintaining enterprise applications using Java, Spring Boot, REST APIs, Microservices, SQL, AWS, and Azure.

I have worked on both greenfield and modernization projects involving backend APIs, batch processing, event-driven integrations, database design, cloud deployments, authentication, and production troubleshooting. My experience includes working with Spring Boot, Spring Batch, PostgreSQL/Aurora, Azure SQL, AWS Lambda, S3, CloudWatch, IBM MQ, OAuth 2.0, and CI/CD pipelines.

Over the years, I have gone through multiple technical interview processes and have developed a strong understanding of what interviewers typically look for in Java backend candidates—not just theoretical answers, but clarity in explaining real-world scenarios, project architecture, debugging approaches, and design decisions.

I currently focus on helping Java developers prepare for backend interviews through mock interviews, targeted feedback, and focused revision across Core Java, Spring Boot, Microservices, SQL, REST APIs, cloud fundamentals, and project discussions.

My approach is practical and interview-oriented: identify weak areas, challenge candidates with follow-up questions, and provide clear feedback on what to improve before their actual interviews.
