Rafi Nazhmi Nugraha

I’m a Frontend Developer specializing in React 19 and Next.js App Router, focused on shipping responsive, high-performance web applications to real users. I work async-first with GitHub, Slack, Jira, and Notion, and I build end-to-end type-safe architectures using tRPC and Prisma. In my AI Training work with Outlier, I reviewed 30+ React/TypeScript code samples per sprint, maintained a 96% inter-rater agreement score across 500+ evaluated samples, and proposed refactoring strategies estimated to reduce code smell density by 40%.

In my projects, I architect type-safe, production-minded features: Talas (a developer social platform) uses tRPC + Prisma for client-server type safety, delivers real-time notifications and a nested comment tree, and achieves a 94/100 Lighthouse score under concurrent read loads—while reducing average image payload by 62% using browser-level compression/cropping before Supabase upload. I also built Gamicus (game discovery) with Zod runtime validation to prevent UI crashes, optimized infinite scroll with IntersectionObserver + TanStack Query caching for sub-800ms loads with no layout shift, and made Pomoductive (a Pomodoro timer) using a stateless timer engine with the Web Audio API for a 98/100 Lighthouse score. I’m seeking frontend engineering roles at remote-first product companies that value strong component architecture, measurable UI performance, and a collaborative async engineering culture.
