Building secure, production-ready software, end to end.

Full-stack developer specialized in building complete web applications, from the interface and APIs to databases, authentication and deployment, with a security-by-design approach. I'm a Computer Systems Engineer with the Cisco CCST Cybersecurity certification. I'm currently building a production web platform used by evaluators at a national merchant marine association, while pursuing a Master's in Data Science to expand my profile into data analysis and artificial intelligence.
