What I'm looking for

I seek backend/cloud roles where I can design scalable, resilient microservices, improve performance and cost-efficiency, and lead operational excellence in an Agile team.

I am a senior software engineer with 10+ years of experience building backend systems using Java, Spring Boot, microservices, and Kafka. I focus on designing secure REST APIs and resilient event-driven services deployed on AWS and container platforms.

Throughout my career I have delivered measurable results in fraud detection, performance tuning, and cost optimization—improving detection accuracy by 32%, reducing response times by 45%, and cutting cloud spend through architecture changes.

I lead UAT, release management, and production support across distributed systems, driving faster incident resolution and more stable releases while implementing CI/CD and operational monitoring.

I'm committed to building scalable, maintainable systems that meet SLAs and business goals, leveraging Docker, Kubernetes, GitLab CI/CD, and observability tools to ensure reliability and continuous improvement.
