Java Backend Engineer focused on building reliable APIs, distributed systems, and production-grade services.

• I build backend systems with Java, Spring Boot, REST APIs, databases, messaging, and cloud-native tooling.
• I go deep into Java internals, system design, operating systems, DSA patterns, and production engineering.
• I have hands-on experience across backend services, API integrations, cloud platforms, CI/CD tools, databases, messaging systems, and scripting.
• I like turning hard technical concepts into practical notes, examples, and repositories for other engineers.
• I am open to collaboration on Java backend, developer tooling, and engineering learning projects.
