Built solo with Tailwind CSS. Still sharpening the edges —
this site is as much a work in progress as I am.

Designed and developed by Justine Lawrence Coronel.

Built with passion and curiosity.

I am a Full-Stack developer and Computer Science student with a growing focus on cybersecurity — particularly secure system design, authentication, and access control. My work also spans back-end database performance and strict, accessible front-end experiences, all built with security as a core consideration rather than an afterthought.
