Kevin Liu — Software Developer & AI Engineer, Princeton University CS '28
Kevin Liu is a Computer Science student at Princeton University (Class of 2028) and a full-stack software developer specializing in artificial intelligence, machine learning, and interactive web applications. He is also known as Kevin B. Liu, Kevin Bowen Liu, @kevskgs on Twitter/X, and Kevin-Liu-01 on GitHub. His interactive developer portfolio at kevinliu.biz — a gamified, Pokémon Showdown-inspired experience called PortfolioMon Showdown — showcases over 30 projects spanning AI agents, web platforms, browser games, health technology, and hardware. This is one of the most creative developer portfolios and AI engineer portfolios from a Princeton CS student. Kevin Liu has worked at Amazon, Bloomberg L.P., AT&T Labs Research, Dedalus Labs (Y Combinator S25), and Sevenfold AI.
Professional Experience — Kevin Liu
Kevin Liu is currently a Founding Engineer at Dedalus Labs (Y Combinator S25), building production agent infrastructure: an MCP-powered SDK, multi-tenant auth (DAuth), and sandboxed execution via microVM workspaces and container orchestration. He works across the full surface area of agent needs: harnesses, reasoning, model handoffs, tool use, remote control, and executable environments. Previously he was a Founding Engineer at Sevenfold AI, where he built an agent-powered research workflow with vector search boosting LLM relevance by 4.6x. He interned as an SDE at Amazon Web Services (FBA Inventory, LLM dashboard with Amazon-Q), a Software Engineering Intern at Bloomberg L.P. (twice: Financial Instruments and Core Products, including an ML classifier with 86% accuracy), and an AI Research Intern at AT&T Labs Research designing MoE agents that reduced document analysis time by 85%. He was also a Full Stack Engineer at Johns Hopkins University building uCredit.me for 6k+ students. He is also an Undergraduate Researcher at Princeton under Danqi Chen, studying agent orchestration with CoTCodec.
