About Me
White-Label Integration Partner for Marketing Agencies
Senior Integration Engineer specializing in Mailchimp, Shopify, and custom API pipelines.
I’m a senior fullstack engineer with 8 years of experience building scalable backend systems, microservices, and high-volume data pipelines.
Most recently, I built e-commerce and integration pipelines at Intuit | Mailchimp, where I engineered event-driven architectures, automated lead syncing systems, and cross-platform integrations with partners like Wix and Canva. Prior to that, I led backend engineering at Modern Tribe, architecting high-availability API infrastructure for high-scale enterprise clients.
Today, I offer white-label integration engineering and technical discovery audits to marketing agencies. When your clients need custom data flows, complex platform connections, or reliable webhook architectures, I handle the engineering behind the scenes so your team can deliver high-value technical solutions with confidence.
