What I'm looking for

I seek backend or platform roles where I can modernize systems, implement CI/CD and microservices, mentor teams, and deliver measurable performance and developer productivity improvements.

I am a results-driven backend software engineer with 4+ years delivering scalable systems, microservices, and full-stack features. I specialize in Java (Spring Boot), Laravel, relational and NoSQL databases, and CI/CD automation, and I focus on clean code, DevOps culture, and business-focused outcomes.

I've migrated monoliths into microservices, built numerous REST APIs, automated pipelines, and optimized performance—reducing latency and deploy times while improving developer onboarding and productivity. I mentor junior engineers and apply TDD and DevOps practices to drive reliable, maintainable systems.
