What I'm looking for

I seek technical leadership roles where I can build scalable full-stack systems, drive cloud-native adoption, and mentor teams in agile, collaborative environments.

I am a Senior Full-Stack Engineer with nine years of experience building high-performance, scalable, and maintainable software across startups and enterprise clients. I focus on bridging product vision with technical execution to deliver measurable business value.

I design and implement RESTful and GraphQL APIs, microservices, and real-time applications using React.js, TypeScript, and Node.js, prioritizing developer experience and system evolvability.

I champion cloud-native architectures and DevOps practices—CI/CD, infrastructure-as-code, automated testing—and have implemented solutions using AWS, Firebase, Docker, and Kubernetes to drive digital transformation.

My work emphasizes accessibility, performance optimization, and secure authentication flows; I consistently raise code quality through testing frameworks and collaborative, agile delivery across distributed teams.
