What I'm looking for

I’m looking for a team where I can build scalable cloud-ready Java microservices, apply event-driven architectures with Kafka, and improve performance and observability—while continuously strengthening CI/CD and testing in an Agile environment.

I’m a Senior Software Engineer and Java Programmer with over 9+ years of core experience in software development, specializing in N-tier distributed architectures, cloud-native deployments, and high-performance microservices.

Across enterprise programs for clients including Siemens, Synchronoss, Walmart, IKEA, and Puma, I’ve delivered scalable backend solutions while optimizing system performance and strengthening technical alignment in Agile environments. I’ve repeatedly focused on building reliable, secure services and improving observability through monitoring and log analysis.

In my recent role, I architected and developed secure, cloud-ready payroll microservices with Spring Boot and Spring AI, using event-driven orchestration with Apache Kafka. I also implemented monitoring with Amazon CloudWatch, automated document extraction and classification using Spring AI’s ChatClient and OpenAI APIs, and ensured quality via comprehensive JUnit 5 tests.

Earlier projects reinforced my ability to engineer resilient REST APIs, improve availability with Hystrix (Circuit Breaker pattern), and raise maintainability by pushing code coverage past 95%. From cart services to automation orchestration and identity-driven e-commerce systems, I’ve consistently delivered production-grade backend components using strong testing discipline, clean API design (Swagger/OpenAPI), and enterprise messaging patterns.
