What I'm looking for

I seek backend or full-stack roles building scalable, secure systems with strong testing and CI/CD practices, collaborative Agile teams, and opportunities to grow into enterprise Java/Spring architecture.

I am a backend-focused full-stack software developer with 5+ years designing, building, and maintaining scalable web applications and distributed systems. I specialize in RESTful API design, relational databases, containerized deployments, and performance optimization.

I've led end-to-end delivery for 50+ client projects across e-commerce, government, healthcare, and enterprise, and I architect solutions using Laravel, Node.js, React, Vue, and Spring concepts. I implement DevOps workflows with Docker, CI/CD pipelines, and deployment automation while enforcing testing, static analysis, and security best practices.

I collaborate well in Agile teams, mentor developers, and translate business requirements into production-ready systems; I'm expanding into the Java Spring ecosystem and enterprise-grade backend architectures.
