Explain a project concisely and deeply

Pick one impactful project and deliver a concise 60–90 second overview, then deep dive. Cover the problem, your specific role, key decisions and trade-offs, measurable impact (with metrics), and the most difficult challenge you faced. Explain how you communicated complex ideas succinctly to stakeholders and how you would improve that communication in hindsight. Conclude with lessons learned and what you would do differently.
