Right Tool for the Right Job — Summary
This is the first post in a new series where we’ll break down the Coder Trader Laws. Below is a summary of Law #1. Stay tuned for the full video presentation.
- Great engineering is about choosing the right tool, not the fanciest one.
- Many devs pick tools for ego or to “flex skills,” which slows them down.
- In trading, using C++/Rust for a simple 1-min strategy is pointless—Python gets you live in a day.
- Discern when to build from scratch vs. using existing solutions (speed vs. customization trade-off).
- This rule applies to life:
- Success relies on discernment—trained through experience, books, mentors, and learning from others’ mistakes.
- Always break problems into sub-problems first, then pick tools that cover all sub-goals with minimal gaps.
- Beware of marketing hype—flashy tools can feel “right” emotionally but be suboptimal.
- Choose tools that fit the job and your skillset, not what looks trendy.
- Personal example: forcing React/Vue when Django was faster, simpler, and fit your expertise → doubled workload.
- Final principle: Don’t choose tools to look smart. Choose tools that help you win.
