Senior Software Engineer · Boston, MA
Ido Katz.
Full-stack engineer
building things that feel fast.
I'm a senior engineer at WHOOP, where I work on the AI Platform team. Previously I built the checkout and subscription experiences behind join.whoop.com and shop.whoop.com.
About
I grew up curious about how things work, which eventually led me to a computer science degree at Worcester Polytechnic Institute and then to WHOOP, where I've been building software since July 2022.
I like the full stack. I've spent time deep in React rendering performance and just as much time in database schemas and payment flows. What motivates me is shipping things real people use — and making those things feel fast, quiet, and dependable.
Outside of work I take photos, play ultimate frisbee, and build the occasional side project.
Experience
What I've built.
- • Designing and operating agent infrastructure used across product teams.
- • Building evaluation tooling so we can ship agent changes with confidence.
- • Full-stack work spanning the agent runtime, the tools around it, and the UIs that expose it.
- • Engineered join.whoop.com and shop.whoop.com to be fast, responsive, and stable across sign-up and purchase flows.
- • Built backend services for cart management, order fulfillment, and address validation.
- • Owned subscription management — renewals, upgrades, lifecycle, and billing edge cases.
- • Partnered closely with design and product to move revenue metrics, not just ship features.
