Justin Karsopawiro

I'm a Lead Engineer with over 10+ years of experience architecting scalable, high-performance web systems. Deep expertise in modern frontend architecture, real-time data visualization, and performance-critical user interfaces.

Currently leading frontend architecture for a mortgage platform at BLINQX. Previously founded and led Webvork, my own consultancy, for eight years. Proven track record designing and owning complex systems end-to-end — from component design and state management to production optimization and developer-facing frameworks.

Proficient across the full stack of modern web technologies, with particular strength in React, TypeScript, Next.js, and Node.js — plus systems-level thinking, performance profiling, and build toolchain optimization.
