What I'm looking for

I’m looking for a team where I can build secure, scalable Java microservices and high-performance REST APIs on AWS. I want ownership over production support and automation, with strong CI/CD and observability to deliver reliable outcomes.

I’m a Java Developer with around 5 years of experience designing and building scalable backend applications using Java, Spring Boot, and Microservices. I focus on clean architecture, code quality, unit testing, and performance optimization to keep systems reliable in production.

I’ve migrated legacy JBoss and Spring Cloud solutions to AWS cloud-native microservices, improving scalability, maintainability, and deployment flexibility. I develop business-critical RESTful APIs using Spring Boot, Spring Security, OAuth2, and JWT authentication, following clean code principles.

I’ve also strengthened messaging and workflow execution by migrating MDB to EDF, and enhancing task assignment workflows to improve DB queries and interaction logic. I improved API response time by 40% using Redis caching, SQL query optimization, and asynchronous processing.

Beyond development, I automate AWS infrastructure provisioning with CloudFormation and set up observability using CloudWatch and OpenSearch. I support production with 99.5% application availability through root cause analysis, performance tuning, and incident resolution, and I’ve implemented CI/CD pipelines using Jenkins to reduce release cycle time by 50%.
