How Eventjoy develops new features fast

Agreed. Eventjoy Developer/Co-founder here. During early stage development, you can't afford to optimize too heavily for technical debt, especially since some features may be thrown out or re-written entirely, but a lot of technical debt is avoidable, and can be mitigated with a few simple practices. My personal top two being:

1. Despite being the only developer, I comment. A lot. We have a large codebase, and I need to be able to understand code I have not touched in months at a moments notice.

2. Modularize. Even if something is being thrown together quickly, I make future-me happy by keeping things as modular as possible from the outset. This allows problems to be isolated a lot faster, and for individual pockets of code to be replaced more easily.

I'd love to hear others' thoughts on managing tech-debt!
