         <h3>Module 3</h3>
         <p>In Module 3, students step beyond the simple one-language-one-framework monolith and juggle multiple domains of responsibility.

         <p>Then, in Module 4, students will choose to "major" in Front End with Javascript/React or Back End with Ruby/Rails. But we'll also emphasize branching out – maybe an FEE major decides to specialize in Angular or a BEE student dives into Python and Django. Along the way, they collaborate in teams on bigger Capstone projects that can mix and maximize all their diverse interests. And we’re excited to integrate outside experts to offer special sessions on subjects like Site Reliability Engineering, SDET, and Application Monitoring and Performance.</p>
