• Partnered with Sales, Marketing, and publisher engineering teams to streamline onboarding, create technical runbooks, and accelerate partner launches.
• Set the technical direction for the shift from a monolith to microservices, splitting out three independently deployable services, Products, Link, and Ads, while the existing AI service continued to run on its own.
• Built REST APIs integrating Shopsense's AI models into the Embeds backend to generate content aware ads across five embed types, on a core AWS serverless foundation using CDK and Infrastructure as Code.
• Gave product teams the ability to validate decisions with real data by designing and launching Shopsense's first A/B testing platform, including experiment tracking, analytics, and feature flag infrastructure.
• Raised release confidence across rapidly evolving products by introducing unit testing and smoke testing practices, and mentoring engineers through code review and pair programming.
