What I Build

Production Backends

I build Java and Spring Boot systems with authentication, service boundaries, database design, REST APIs, and event-driven flows that are meant to survive real users.

record Stack(
    String backend,
    String messaging,
    String cloud,
    String principle
) {
    static Stack current() {
        return new Stack(
            "Java 17 + Spring Boot 3 + Security",
            "Kafka + Solace PubSub+",
            "AWS + Firebase + Docker",
            "Strong fundamentals scale better"
        );
    }
}

Learning Systems

I turn complex engineering topics into placement-focused roadmaps, live workshops, and project-based learning paths for Java, DSA, frontend, and full stack development.

now shipping:
  - CRM modules and invoice flows
  - Event-driven integration patterns
  - Java + DSA teaching tracks
  - AWS SAA preparation
