about me

Engineer who owns the lifecycle

I'm a Full Stack & Automation Engineer with 6+ years of experience building and shipping production-grade systems across healthcare, government, real estate, and food-tech.

I work across the entire stack — from system architecture and API design to cloud infrastructure automation and CI/CD pipelines. I take ownership of problems end-to-end and deliver solutions that are performant, maintainable, and built to scale.

I've worked directly with clients, led cross-functional teams, and consistently delivered on tight deadlines without compromising code quality. The best engineers aren't just coders — they're communicators who build the right thing, the right way.
