What I'm looking for

I'm looking for opportunities to innovate in secure web application development and collaborate with talented teams.

I'm a dedicated Front-End Engineer with a strong focus on developing secure web applications that enhance user experience and streamline processes. Currently, I work at Synchrony Bank, where I maintain core authentication web modules and create external-facing APIs that integrate internal services with partner platforms. My commitment to security and efficiency drives my work, ensuring that all stakeholders have secure access to vital information.

Previously, I served as a Full Stack Engineer at ONEai Health, where I led the development of a patient data management system compliant with HIPAA regulations. My role involved creating advanced filtering functionalities and implementing role-based access control to protect sensitive patient information. I thrive in collaborative environments, leveraging my skills in JavaScript, TypeScript, and React to deliver high-quality solutions.
