ABOUT DAN WALSH
Software engineer with 8+ years of experience, primarily in frontend development with React, TypeScript, and Node.js. Now focused on integrating AI into practical development workflows.I\'ve led infrastructure modernisation projects affecting 30+ developers, pioneered AI-powered development improvements (automated test generation reducing effort by ~60%, business logic documentation), and built internal tooling that bridges what AI can do with what engineering teams actually need.Currently exploring MCP servers, Claude Code skills, and the practical side of AI integration — the work that makes AI genuinely useful rather than just impressive.Looking for engineering-first companies where I can combine deep frontend expertise with emerging AI capabilities.
