About
Engineer with a product lens
I work best where product clarity, visual polish, and system design need to come together. My sweet spot is architecting end-to-end platforms that feel thoughtful from the first scroll to the final deployment.
Over the past six years I have worked across product strategy, frontend architecture, backend systems, CMS platforms, and deployment workflows. My focus is building software that feels polished for users, maintainable for teams, and measurable for businesses.
