What problem does it solve? Learners who have practiced whiteboarding drills often never test their diagrams against a real audience, so gaps in clarity go undiscovered. This capstone closes that loop by having the learner present a real system to a real human, capture every question asked, and redraw the diagrams based on that feedback. ## Core Features & Use Cases - Structured 5-phase workflow: pick a system, prepare four diagrams (architecture, sequence, state machine, ER), deliver a recorded 15-minute presentation, categorize audience questions, and redraw v2 diagrams. - Feedback-driven iteration: every audience question is categorized (missing component, ambiguous label, wrong shape, missing arrow verb, wrong diagram type, out of scope) and mapped to a concrete diagram fix. - Written reflection artifact: produces a ~300-word reflection comparing v1 vs v2 as a portfolio piece and track-completion record. - Use Case: A learner finishing the Whiteboarding track picks their to-do API project, draws four diagrams in Excalidraw, presents to a study partner for 15 minutes while recording, logs six questions, redraws the diagrams to answer them, and writes a reflection. ## Quick Start Ask the mentor to start the whiteboarding capstone and help me pick a real system to present with four diagrams.
