Shubham Chaurasia

As a Senior Software Engineer at Meta, I thrive at the intersection of complex systems, web performance, and developer experience. My career is defined by a commitment to engineering excellence—from driving large-scale architectural transformations to leveraging emerging AI technologies to solve the industry's toughest challenges. Currently, I contribute to the architecture of Meta's Ads Manager, the world's largest React application. My work centers on ensuring top-tier performance and reliability for this mission-critical platform, employing rigorous observability practices to minimize browser crashes and optimize user experience at scale. My recent focus centers on "AI-assisted engineering." By building production-grade AI codemod pipelines, I have demonstrated how non-deterministic agents can be constrained to perform reliable, deterministic transformations—migrating over 3,000 components with a 99.6% success rate, significantly reducing technical debt while maintaining velocity for over 1,200 active developers. With a background spanning engineering leadership at Groupon to infrastructure work at Meta, I specialize in re-architecting consumer-facing applications and fostering high-performance engineering cultures. Whether it's diagnosing complex performance bottlenecks or designing scalable AI-driven development workflows, I am driven by the goal of making engineering more efficient, reliable, and developer-friendly.
