Activities

historical

Full-stack developer and founder of Ping.gg and the T3 Stack (Next.js + TypeScript + Tailwind + tRPC + Prisma). Built a developer following through strong TypeScript advocacy and opinionated web development content.

present

Developer educator covering TypeScript, React, full-stack web development, and increasingly agentic AI coding workflows. Runs t3.gg. 47 videos in dataset. Known for critical takes on JavaScript ecosystem trends and honest analysis of AI coding tools.

Content style

Opinionated and developer-authentic. Known for rants, technical critiques, and year-in-review analysis. Engages critically with AI coding tools rather than hyping them — identifying real problems (context fragmentation, YOLO modes, browser/localhost collisions in parallel agentic dev). High-engagement audience of senior developers.

Key topics covered

• TypeScript, React, and the T3 stack
• Agentic coding workflows and their practical problems
• Claude Code, Codex, Cursor comparisons
• Developer UX challenges in parallel local development
• Reasoning models and AI coding agent evolution
• MCP/skills and tool integration patterns
• AI safety and “normalization of deviance” in agentic coding
• Observability for AI agents (Sentry agent dashboard)
