I have over 20 years of experience in software development, as a senior engineering manager and principal developer. Most recently, I led several teams at Etsy in Trust & Safety and Customer Service product engineering. My teams were anti-money laundering, content moderation, buyer support, and seller support. I managed 3 managers and a single team of up to 12 engineers. I focused on coaching and mentoring, resulting in several promotions. I led cross-functional projects like detecting and filtering unexpected mature content. I coordinated with a dozen teams including search, recommendations, ads, and mobile. I collaborated with product, design, analytics, and business to reduce unexpected mature views by 29% and customer reports by 17%.Previously, I was a principal consultant at ThoughtWorks, a player coach role that is both senior engineering manager and principal developer. I led full-stack teams building custom software focused on e-commerce, platforms, mobile, fintech, and DevOps. Some example projects are:•The Gap - Migrated their e-commerce platform into Azure, introduced Microfrontend architecture and incorporated A/B testing. This resulted in increasing revenue per visit by 1.8% and improving page load speed by 50%.•H&R Block - built a mobile chat-based tax preparation app. Built in hybrid mobile with tight timelines and ready for tax season.•ThoughtWorks Studio - built and operated SaaS continuous integration and delivery service.I have worked with a wide variety of technologies including AWS, Azure, GCP, JavaScript, TypeScript, Ruby, Java, MySql, PostgreSql.I'm always looking to grow my personal and professional network.
