I'm Lead Software Engineer at LottieFiles, where I maintain the official dotLottie player stack end to end: dotlottie-rs (a production Rust runtime compiled to WebAssembly for the web and to native iOS/Android libraries from one codebase) and dotlottie-web (the TypeScript player and its React/Vue/Svelte/SolidJS packages — 10M+ npm downloads/month). The runtime parses untrusted third-party files on every client installation, so memory safety, input validation and frame-budget performance are my daily constraints. Before that: backend at TikTok on systems serving hundreds of millions of users, and 3 years of enterprise React/TypeScript at Adform. I also contribute to ThorVG (C++ vector graphics engine). Looking for senior/staff systems, runtime, graphics, or frontend-infrastructure work — remote from Indonesia or relocation with sponsorship.
