Deep Dives

As you’re building, you’ll want to go in deeper into specific areas of frontend and backend development. These deep dives are designed to help you gain deeper knowledge in specific areas.

We recommend you write a blog post about your learnings (once every 2-3 weeks) and share it online. Recruiters and hiring managers love to see that you’re proactive about learning and growing, and don’t just have surface-level knowledge.
