Callum Huang
IOS SDK Engineer at BBPOS | A Stripe company
Taiwan
Summary
👤
SeniorCallum Huang is an iOS SDK Engineer with 10 years of experience building payment and finance-focused mobile and backend systems across Taiwan and international teams. He has shipped production iOS apps and SDKs using Swift (RxSwift), MVC/MVVM patterns, and modern tooling (CocoaPods, SPM, Fastlane), and pairs that with backend expertise in Spring Boot, MySQL, gRPC/REST APIs and GCP. Recent roles include iOS development at Crypto.com and SDK work at BBPOS (a Stripe company), reflecting deep domain experience in payments and security-sensitive integrations. He excels at cross-cultural collaboration—frequently coordinating with Japanese and distributed teams—to align API design and product flows. Pragmatic about hiring processes, he prefers written communication and values opportunities that include clear job and compensation details. Less obvious: he routinely straddles mobile and server responsibilities, enabling faster iteration on end-to-end features rather than siloed handoffs.
