Senior Staff Engineer

Driving change through data at Optimizely, the world’s leading experimentation platform. Led large company-wide projects in product development, product delivery, and billing. Occasionally, I get to speak at conferences large and small about these projects. Focus on initiatives driving high-performing engineering organizations (eg DORA Accelerate), such as: - Higher velocity through more frequent deploys and smaller changesets - Driving engineering experimentation with feature flags/gating - Building infrastructure (tooling) to decrease operational burden. - “Shifting left” on QA, experimentation, security, etc to increase overall developer velocity Much of my day-to-day at Optimizely is spent driving large projects across the company. In general terms, these are tough problems that are difficult to solve and require 9 - 12 months at a time across multiple teams and departments.
