I tackled a major hurdle for our enterprise teams: building a system that lets reps share a territory while keeping their accounts private. This was a total shift in how our product logic worked, which meant a high risk of making things messy for admins. I took charge of the design and worked closely with our engineers and support teams to make sure the transition was smooth. After a few rounds of post-launch tweaks, we landed on a solution that keeps data secure without slowing anyone down.
