Andy Deng
Full-Stack Product Engineer
I'm a full-stack product engineer, currently at Pega, where I'm responsible for end-to-end development of Blueprint features and enhancements across the frontend and backend. I have expertise in modern TypeScript, Next.js, and event-driven backend systems to develop elegant user experiences, scalable backend architecture, and robust LLM infrastructure.
I'm independent, work fast, and ship at quality. The work I find most rewarding sits where product meets infrastructure, where decisions compound and the technical bar is high enough to keep learning. Outside of work, I build across AI, developer tooling, and web. Recent projects include Remes, an AI-powered outbound sales platform, sigdiff, an open-source npm package for semantic code diffing, and Leafpad, a developer tools suite with 1,200+ monthly active users.
I'm drawn to scale and to teams that take engineering seriously. I want to work on products used by millions, where the problems stay hard enough to grow into and the quality of the work shows.
