Work Experience

Frontend Engineer

Expedium

Jul 2024 - Present

Led a team of 5 engineers building core EHR platform modules (Appointments, Visit Notes, Patient Chart, Demographics) in React and Redux, taking ownership of the modules and driving architecture decisions and code reviews. Led migration from CRA to Vite and implemented CI/CD pipelines — cutting local dev server startup time by roughly 50% and pipeline build time by around 30%. Configured AWS S3 for secure storage and retrieval of patient documents and exported reports, integrating it with the platform's PDF/CSV export engine. Implemented role-based access control (RBAC) across EHR modules so clinicians and staff access only the data appropriate to their role, supporting healthcare data-compliance requirements. Architected hardware-software bridges by integrating Dynamsoft Web TWAIN (DWT), enabling direct multi-page document scanning and managing real-time device state for connectivity, printer status, and scanning progress. Automated medical labeling via the DYMO Label SDK, and used AI-assisted development tools throughout the workflow to speed up debugging, code review, and boilerplate generation.

The 10xAcademy

Jan 2022 - Mar 2023

Independently engineered an automated grading system for React assignments using Jest and Mocha, executing real-time test cases and delivering instant feedback to students. Migrated marketing sites from PHP to Express.js, implementing server-side rendering and CI/CD deployment workflows — cutting average page load time by around 30% and improving organic search rankings. Used AWS S3 for storing and serving static assets and student submission files across GCP-hosted applications. Implemented role-based access control (RBAC) for the student portal, separating student, instructor, and admin permissions. Architected scalable features for the student portal using Next.js and Go, leveraging GraphQL for efficient data fetching, and managed three high-traffic marketing sites for high availability and seamless user acquisition.
