How I Manage 400K Lines of Code with Claude Code: A Multi-Agent Development Workflow
A battle-tested workflow for using Claude Code to manage large-scale projects with parallel AI agents working like a distributed engineering team
$1 Million Per Week: My Seven-Week AI Development Sprint
I delivered $1 million worth of software per week for seven straight weeks using AI. Traditional COCOMO values the 219,400 lines of executable code at \(7.8M. My actual cost: \)636 in AI subscriptions. This is how I did it.
🚀 Git Worktrees + Claude Code: The Developer's Guide to Parallel AI Workflows
How developers are using git worktrees with Claude Code to run multiple AI agents in parallel—early patterns, real implementations, and practical setup guides.
Why IRC §174—Not AI—Killed Tech Jobs
Tech layoffs between 2022 and 2025 weren’t caused by AI automation—they were triggered by a forgotten clause in the U.S. tax code: the expiration of full R&D expensing under IRC §174. Learn what really happened, why it matters, and how to respond.
