Summary
🤩
Rockstar🎓
Top SchoolKartikaya Gupta is a seasoned software engineer with 14 years of experience building graphics-heavy systems, back-end services, and developer tooling across companies like Mozilla and Cash App. He was the owner of Mozilla’s asynchronous panning and zooming module and has deep practical expertise in rendering and WebRender integration, reflected in contributions to high-profile open-source projects such as servo/webrender and mozilla/treeherder. Kartikaya blends front-end polish with low-level systems work—implementing C bindings for Rust, improving libgit2 bindings, and hardening build tooling and cacheability for projects like square/wire. At Cash App he continues to focus on reliable backend services and gRPC/SSL behaviors, while his long history includes architecting browser rendering at BlackBerry. He pairs a Master’s in Computer Science from the University of Waterloo with a proven ability to move between UI, graphics, and infrastructure codebases, often surfacing non-obvious improvements like ABI-safe code generation and build relocatability.
