03

Gaps & Adaptation

Adaptable

Direct experience in high-stakes testing security.

Timeline: 4 weeksHandled HIPAA-compliant EHR (EKAGRA) and GDPR (Jamahook) — security as a core product surface is familiar territory.

04

Difficult Questions

Answering the hard parts of the role with experience and empathy.

How do you balance 'every pixel matters' with 'execute with urgency'?
Empathy for the user and the builder. At Haiba, I shipped image-to-table ordering in weeks by focusing on the 'invisible' UX — latency and dignity. We didn't ship the perfect UI; we shipped the perfect *feel*. I use Storybook to ensure 'pixel-perfect' is a shared language, not a bottleneck.
How do you handle security vs. UX in a high-stakes environment?
Compliance is a product surface. At EKAGRA (HIPAA) and Jamahook (GDPR), security wasn't a back-office task; it was the foundation. In DET, security is the product's value. I'd lean on agentic workflows to detect patterns of fraud while keeping the candidate's flow friction-less.
What brings you beyond the requirements?
Operator scar tissue. I don't just manage a product; I've structured founding teams and cultural values. I bring a founder's perspective to the DET — I look at unit economics and staff joy alongside user growth.
