As a solo engineer building production systems, I need tools that replace an entire team: project manager, QA engineer, DevOps engineer, security analyst, and designer.
Here's my actual toolkit — not aspirational, but what I use daily.
Development
Tool
Replaces
Why
Claude Code (CLI) Pair programmer
Code reviews, architecture discussions, debugging
GitHub Copilot Junior developer
Boilerplate, test generation, documentation
VS Code IDE (obviously)
Extensions: ESLint, Prettier, GitLens, Tailwind
Cursor Code navigation
When I need to understand a large codebase fast
Operations
Tool
Replaces
Why
