Nael Jeffrey

I've built and optimized trading platforms at PT. Byte Integrasi Global and PT. Yuanta Sekuritas Indonesia, delivering real-time web and desktop experiences with React, Next.js, Tauri, WebSockets, and FastAPI. For a high-volume trading workflow, I reduced frontend memory consumption from approximately 3 GB to around 1 GB and improved successful trade processing to approximately 90% through queue-based transaction synchronization. I also built AI chat, community-stream, OAuth 2.0, multi-factor authentication, monitoring, testing, and load-testing capabilities for production trading applications. At MoonLab, I've delivered fiat-to-crypto and crypto-to-fiat functionality adopted by more than 2,000 Android and iOS users, reduced first-time login time from approximately 9 seconds to 4 seconds, and streamlined Firebase usage from more than 10 API calls to 3. I've also contributed to secure cloud infrastructure, internal software-development platforms, AI-assisted engineering workflows, and Go backend capabilities including RBAC and multi-tenancy. Across fintech, Web3, SaaS, and data projects, I work end to end: frontend architecture, backend APIs, cloud infrastructure, CI/CD, observability, testing, and real-time systems. I bring experience with React, React Native, TypeScript, Go, Python, Terraform, Docker, and modern full-stack development practices.
