What I'm looking for

I am seeking remote roles where I can build secure, scalable web systems, focus on DevOps and security, collaborate in multidisciplinary teams, and continue growing in data and AI applications.

I am a Full-Stack Developer and Software Engineer with a foundation in Civil Engineering and a specialization in Data Science, focused on building secure, scalable applications.

I have developed complete systems across front-end, back-end, databases, and DevOps, delivering RESTful APIs, interactive interfaces, and automated CI/CD pipelines.

My work highlights include encryption and API hardening for secure projects, a 300% SQL query improvement through composite indexing, and contributions to generative AI research and prompt engineering.

I thrive in remote, multidisciplinary teams, enjoy performance optimization and security-first design, and regularly deliver end-to-end solutions and production-ready deployments.
