About Me

Learn more about my background, skills, and passion for technology

Hello! I'm Pavana HA

I'm a passionate Backend Developer with 2+ years of experience in building robust server-side applications and scalable systems.

My journey in tech started during my Computer Science degree, where I discovered a deep interest in system design, databases, and server architecture. Since then, I've been continuously learning and working with modern backend technologies, specializing in microservices architecture, event-driven systems using Kafka, and implementing end-to-end CI/CD pipelines for efficient delivery and deployment.

While backend development is my core strength, I’m also comfortable working on the frontend using React, enabling me to contribute to full-stack solutions when needed.

When I'm not coding, you can find me contributing to open source projects, exploring the latest trends related to tech.
