Senior Software Engineer
Hello, I'm Vamsi Krishna
I build cloud-native, event-driven enterprise systems using Java 17, Spring Boot, Kafka, AWS, React, Angular, and distributed microservices architecture.
Open to Senior Software Engineer roles focused on Java, Spring Boot, Kafka, AWS, React/Angular, distributed systems, and enterprise modernization.
About
Backend-leaning full-stack engineer focused on reliable enterprise systems, clean architecture, production support, and cloud-native delivery.
Engineering Focus
My work centers on Java/Spring Boot microservices, Kafka-driven workflows, secure REST APIs, React/Angular dashboards, AWS deployments, and production support for distributed systems.
How I Work
I care about clear service boundaries, readable code, practical observability, database performance, secure access patterns, and systems that are easier for teams to debug, deploy, and maintain.
