About

I am a secure software engineer with six years of full-stack development experience, currently completing my Master of Science in Software Engineering at San José State University. I specialize in application security, container hardening, and DevSecOps pipelines. Having built highly scalable cloud platforms and infrastructure automation tools like @ianbunag/dock, I leverage my background in automated testing and cloud-native architecture to build secure and resilient systems. I am currently seeking a Summer 2027 internship in Secure Software Engineering, Application Security, or DevSecOps.

Front-End development
I convert design prototypes into responsive and accessible web applications. I utilize modern frameworks and design systems to seamlessly bridge technical execution with creative visual design.
Back-End Development
I engineer scalable, secure, and modular backend services. I build robust systems across managed and serverless environments with comprehensive test coverage.
DevOps & Infrastructure
I accelerate development cycles through automated CI/CD pipelines via CircleCI. I leverage Docker for containerization and provision reliable, scalable infrastructure using Terraform.
