Harshil Patel
A software engineer with a passion in full stack development and competitive coding. MS in Software Engineering from San Jose State University, currently building messaging infrastructure at Meta Platforms.
I excel in developing fast, scalable, and smooth software for enterprises.
4+ years of experience building large-scale distributed systems and frontend platforms. At Meta, I delivered $1.5M+ in combined annual OPEX savings by modernizing messaging infrastructure across Facebook, Instagram, and Threads. Previously built React component libraries and KPI dashboards at an AI startup, saving 125+ engineering hours per month.
Strong in React, TypeScript, Node.js, and distributed systems. I care about writing clean, performant code and shipping things that move metrics.
