Hacker Fellows Technical Program Overview

In the 2019 Hacker Fellows Bootcamp you’ll have an opportunity to experience a workflow similar to that of a real production development team while learning the principles of building maintainable software.

The curriculum will consist of four modules: Test-Driven Development, Refactoring Techniques, Object-Oriented Design and Database Design/Object-Relational Mapping.

During the first week of the class, which is actually a short 3-day week, the fellows will be divided into teams to work on a short but challenging project. At the beginning of the next week, you’ll form new teams, and each team will “inherit” another team’s project. This will simulate the real-world challenge of having to work with other people’s unfamiliar code. This regrouping and project handoff will happen at the start of each full week.

Throughout each week your job will be to apply the principles taught that week (e.g. object-oriented design principles) to make improvements to the codebase, with the object being to leave the codebase at the end of the week cleaner than you found it. At the end of each week you’ll be asked to do a presentation with your team about what you did and what you learned.
