What I'm looking for

I seek backend roles focused on microservices, API performance, and cloud integration at teams prioritizing reliability, scalability, and collaborative engineering.

I am a Java developer with two years' experience building secure, scalable microservices and RESTful APIs, with hands-on work in event-driven systems and cloud integrations.

At Xebia, supporting Air India, I improved API response time by 30% using Redis and Caffeine caching, implemented Kafka-based workflows, integrated third-party APIs with Feign, and managed Azure Blob Storage and Liquibase-driven schema versioning.

I focus on performance, reliability, and security, and I bring practical experience in database design, API documentation (OpenAPI), automated notifications, and improving developer onboarding.
