Selected work
- Tables Redesign — DRI on a redesign that made Tables more than a spreadsheet, from first plan to staged rollout.
- Chat with Support — A one-click handoff from Builder Copilot to a live support agent, based on each user’s plan and where they are.
- LLM as Judge — A judge that grades whether Copilot’s answers say the right thing, with rules that keep it from blocking a release until it’s been validated.
- Enrich — AI that fills in one or more fields from a prompt built on your other fields.
- Linked Records — One of Tables’ most-requested features: fields that reference records in another table.
- Sample Data — Generated sample records, so someone opening an empty table has somewhere to start.
About
Kate has spent 15+ years building products, from first engineering hire at a clinical-trial startup (SignalPath, acquired by Verily) to five teams and seven products at Zapier. She loves the messy middle and the unglamorous work that keeps a product running. She is earning an M.S. in Computer Science at Georgia Tech, specializing in AI.
Education
- M.S. in Computer Science, Georgia Institute of Technology. In progress, specializing in AI
- Communications, PR, Digital Media, East Carolina University
- Digital Media Arts, Computer Science, Huntington University
Approach
Three habits that carry across projects.
- Discover — She starts by finding out what the system does today. Then she turns the fuzzy problem into a plan with a clear first step, grounded in real users and data.
- Build — She breaks risky work into small pieces that are easy to review and safe to ship. When other teams need something, she builds it as a tool they can use.
- Launch — She rehearses the risky parts and sets the quality bar before rollout. She makes sure failures get noticed, and that feedback the team doesn’t get to has somewhere to go.
