(The full story of why that backend was eventually migrated from Laravel to Go, across 370+ endpoints, is documented in my <a href="https://najib.id/en/writing/2026/hijrah-backend-01/">Hijrah Backend narrative series</a>. The series you are reading right now is the tutorial counterpart: rebuilding the architecture from scratch, complete with code you can follow along with.)</p>
