I'm building responsive product experiences at KNOW, including a web-based Guides/SOP module that brings mobile workflows to mobile, tablet, and desktop.
I implemented real-time guide lists, comments, likes, and bookmarks with Firebase Realtime Database. I also developed PDF content search backed by PostgreSQL, with relevance ranking across guide identifiers, titles, and document content.
At Codestax.ai, I designed and developed a Fixed Asset Management System using Node.js, PostgreSQL Aurora, AWS Lambda, and API Gateway. I built JWT-based role access controls with Firebase, reducing authentication issues in testing by 80%, and improved initial API latency by approximately 25%.
I've also improved frontend performance through code splitting and lazy loading, trained junior engineers on Vue 3 and Vuex, and built a drag-and-drop form builder for non-technical users.
