- Undocumented decisions made pre-hire become invisible landmines for the first engineer.
- A codebase that's at least reasonably organized is worth more than one that's merely fast to write.
- Basic version control and deployment practices should exist before anyone else touches the code.
- The first engineering hire should inherit context, not just code with no explanation.
Undocumented decisions become landmines
Shortcuts and assumptions baked into an early codebase, with no record of why they were made, force a new first engineering hire to spend real time reverse-engineering decisions instead of building. A short written log of key early decisions saves that time later.
Reasonably organized beats merely fast
Code written as fast as possible with no structure at all is harder for a new engineer to safely modify than code that's a bit slower to write but reasonably organized. That tradeoff matters specifically at the moment a second person needs to work in the same codebase.
Basic practices should already exist
Version control, a documented way to run the project locally, and some form of deployment process should already exist before a first hire arrives — these are foundational, not optional, and their absence costs a new hire days just figuring out how to get started.
Hand off context, not just code
A first engineering hire who receives a codebase with no explanation of the product's history, the reasoning behind key decisions, or known issues will move slower than one who gets even an informal walkthrough. That context transfer is worth the founder's time investment.
