My Claude Code Journey: The Developer Skills I Had to Learn
A reflection on lessons learned during a Summer 2025 internship at Best Path Research in Tokyo, building a business simulation game with Django, Python, and Claude Code as a development assistant.
“AI doesn't make you a better developer by being right; it makes you better by challenging you to think critically about everything it produces.”
Key takeaways
- ▸Without precise, first-principles instructions AI will overcomplicate simple tasks
- ▸Prompt engineering is a critical technical skill comparable to traditional programming
- ▸Working with AI is like advanced rubber duck debugging: articulating the problem clearly often solves it before code is generated
- ▸AI-generated code requires constant defensive verification, especially for business logic edge cases
- ▸Designed a 27-module Python testing framework that saved 40+ hours per testing cycle
- ▸Architectural decisions and system design remain entirely the developer's responsibility
