What I'm looking for

I’m looking for a team that values scalable microservices, API performance, and secure engineering. I want to build data-intensive pipelines, improve CI/CD reliability, and grow by shipping measurable improvements in latency, quality, and maintainability.

I’m a Full Stack Software Engineer with 2+ years of experience architecting scalable distributed systems using Java, Spring Boot, and React. I specialize in Microservices and API optimization, with a track record of reducing latency by 25% and increasing deployment frequency through Agile best practices—while staying committed to writing clean, maintainable code.

At Cognizant Technology Solutions (Client: Royal Bank of Canada), I helped modernize and secure enterprise banking systems by migrating RHEL 7 to RHEL 8 (10% processing efficiency boost) and improving CI/CD reliability by 20% across 10+ microservices through Artifactory and standardized repository structures. I implemented Spring Security and JWT to enforce strict OWASP compliance and reduced security vulnerabilities by 20%, then eliminated data inconsistencies with robust Java/Spring Boot transformation logic (100% mapping accuracy for critical risk modules). I also built high-volume batch-streaming pipelines using Apache Kafka and Apache Spark for RDL risk data, reducing latency by 30% with exactly-once delivery, and strengthened quality by using JUnit and Mockito to reduce post-production defects by 15%.
