During my time as a Freelancer at EMMA Worldwide, I collaborated directly with leadership to modernize legacy workflows through custom technology solutions. A standout project was the development of an internal UPS tracking application built with Next.js 15 (App Router), React 19, and TypeScript, utilizing the Shippo SDK for real-time multi-carrier logistics. I implemented a robust architecture using Prisma ORM and PostgreSQL, with secure authentication via NextAuth.js, and managed deployment on Vercel leveraging serverless functions and edge middleware. By also engineering bespoke Python and JavaScript automation tools to streamline client communication pipelines, I successfully reduced manual overhead and accelerated organizational response times.
