- Designed and launched Shopsense's first A/B testing platform, implementing experiment tracking, analytics, and feature flags that enabled product teams to validate hypotheses and make data-driven product decisions.
- Scaled the engineering platform within a Turborepo monorepo by introducing shared TypeScript packages, reusable UI components, GitHub Actions CI/CD pipelines, automated deployments, review and reprocessing workflows, and operational dashboards that improved developer productivity and release reliability.

How This Portfolio Was Built
This portfolio is itself a technical showcase — a Turborepo monorepo with two Next.js apps, server-side AI chat, and edge-cached performance.

Built with AI Assistance
I used AI tools (Cursor + Claude) to accelerate development of this portfolio — architecture design, code generation, and content optimization. Every decision was validated, every line was reviewed. AI is my co-pilot, not my autopilot.
