1 Month, $5000 in AI Subscriptions and Tokens. I’m one person. With Claude Code + Codex + Copilot, I built 18 distinct systems. ~50k lines of code. If you hired 2 full-stack engineers to build this from scratch, it’d take 6–12 months and cost ¥300k–600k. Here’s what I built in each section 👇 (1/7) 【Quant Trading + Blog Traffic Acquisition】 🧠 Quant: Polaris strategy versions 1/5/6 live trading, dual-machine hot standby, backtesting lab v2 (Numba JIT + Walk-Forward + Monte Carlo + multi-symbol portfolio), desensitized Mac standby. ...
