What I'm looking for

I seek roles where I can lead backend architecture and modernization efforts, work across full-stack/DevOps boundaries, mentor teams, and deliver measurable performance and reliability improvements.

I am a Senior Software Engineer with 7+ years building scalable backend systems using PHP (Laravel), Node.js, and AWS. I focus on designing secure RESTful APIs, modernizing legacy systems, and improving performance and maintainability.

At Symplicity I led modernization efforts, improved code quality, and contributed to system stability through testing and monitoring, reducing technical debt and enhancing platform reliability. I mentor junior engineers and participate in technical hiring.

While contracting at Amirom Express I architected a microservices-based international logistics SaaS, improved dashboard performance, implemented enterprise security standards, and delivered measurable business impact like reduced manual entry and support for international shipments.

I have full-stack experience (React/Next.js, TypeScript, Vue.js) and strong DevOps practices (Docker, AWS, CI/CD). I work well in Agile teams and prioritize clear documentation, maintainable architecture, and measurable improvements.
