02 — AI workflow

How I work with AI

AI-augmented development is not «code on demand» — it is an engineering discipline: AI agents work under clear specifications and are cross-checked by each other and by a human.

Architectural decisions, fact-checking, security and final responsibility stay with the engineer. This process is what made it possible to run dozens of projects in six months without losing quality.

Tools: Claude Code (subagents, slash-commands, skills, hooks, MCP), OpenCode, superpowers, MCP to the production DB and SSH, Playwright.
