Every developer has a voice in technical decisions through proposals and RFCs; we learn, build, and improve together. Our team works in a Scrum framework with 2‑week sprints, combining focus and flexibility. Each sprint starts with clear goals and ends with a review and retrospective to continuously improve our process. We value transparency, shared ownership, and cross‑team collaboration so everyone knows how their work impacts the product.
