Location: San Francisco, California, United States
Profile: https://flows.cv/crystall1

I’m a Full-Stack Software Engineer at GGI, where I develop advanced 3D printing software that bridges user experience with hardware precision. I lead front-end development using React.js and Vue.js to build intuitive, responsive interfaces, while also contributing to backend services built with Django and managing PostgreSQL databases to ensure scalable and reliable data flow. I also leverage AI and LLM-powered tools to prototype features, automate documentation and workflows, and improve developer productivity.

My work spans the full development stack—from crafting user-facing features that provide real-time control and monitoring of the printing process, to integrating with machine-level systems for smooth operator workflows. I thrive in cross-functional teams and take pride in delivering production-grade software that powers high-performance manufacturing.

With a strong interest in finance, economics (CFA Level I certified) and security, I’m passionate about applying engineering and data-driven thinking to solve impactful real-world problems at the intersection of technology, manufacturing, and security.
