At Mengantar, I replaced duplicated order logic across six carriers with a reusable abstraction, cutting new-provider onboarding from one week to one day. I also delivered a Drop Shipper feature across seven carriers and redesigned order processing around asynchronous queues, bulk writes, and retries.
At Lion Parcel, I standardized a Go backend pattern adopted across services and squads, and built Goroutine-based pipelines that reduced memory use and processing time. I’ve also shipped recurring payments and pay-later features at Tunaiku (Amar Bank), and built full-stack products for consulting clients and personal projects.
