As a software developer, and especially as a senior (expensive) software developer, you need leverage. Leverage makes you more productive.  I find it also makes the job more fun.

Some forms of leverage:

  • test suite. A suite provides leverage both by serving as a living form of documentation (allowing others to understand the code) and a regression suite so that changes to underlying code can be made with assurances that external code behavior don’t happen.
  • libraries and frameworks, like Rails. By solving common problems, libraries, open source or not, can accelerate the building of your product. Depending on the maturity of the library or framework, they may cover edge cases that you would have to discover via user feedback.
  • iaas solutions, like AWS EC2. By giving you IT infrastructure that you can manipulate via software, you can apply software engineering techniques to ensure validity of your infrastructure and make deployments replicable.
  • paas solutions, like Heroku. These may force your application to conform to certain limitations, but take a whole host of operations tasks off your plate (deployments, patching servers). When a new bug comes out affecting Nginx, you don’t have to spend time checking your servers–your provider does. When you reach a certain scale, thost limitations may come back to bite you, but in the early days of a project or company, having them off your plate allow you to focus on business logic.
  • saas solutions, like Google Apps or Delighted. You can have an entire business solution available for a monthly fee. These can be large in scope, like Google Apps, or small in scope, like Delighted, but either way they solve an entire business problem. You can trade time for money.
  • experience, aka the mistakes you’ve made on someone else’s dime. This allows you leverage by pruning the universe of possibilities for solving problems, based on what’s worked in the past. You don’t spend time doing exploration or spikes. Note that experience may guide you toward or away from any of the points of leverages mentioned above. And that experience needs to be tempered with learning, as the software world changes.
  • team. There’s only so much software you can write yourself. A team can help, both in terms of executing against a software design/architecture and improving it via their own experience.

Leverage allows you to be more productive and the more experienced you get, the more you should seek it.
