What I'm looking for

I seek a backend/cloud-focused role in an Agile team where I can improve system reliability, mentor engineers, and build scalable, cloud-native services with strong CI/CD and observability.

I am a results-driven Senior Java Software Engineer with six years of experience building backend systems using Java, Spring Boot, microservices, and cloud platforms. I specialize in designing scalable, maintainable architectures, improving system performance, and reducing latency for high-demand environments.

I've delivered measurable improvements including multi-cloud resiliency, reduced real-time processing latency from five to one minute, and enhanced CI/CD pipelines to shorten delivery times. I have led distributed teams and contributed to large-scale systems used by millions of end users while migrating critical applications to modern frameworks.

I thrive in Agile teams and prioritize clean, testable code, automated deployments, and observability. I seek roles where I can continue improving system reliability, mentor engineers, and deliver cloud-native services that meet strict performance and security requirements.
