Message

At USBC, I led a distributed team of 10–12 iOS engineers and built an automated issue-to-PR pipeline using Claude Code and Linear API. I also architected security for a non-custodial wallet, including Keychain storage, biometric authentication, and end-to-end encryption.

I modernized the iOS codebase with Swift Concurrency and modular Swift Package Manager architecture, eliminating runtime data races and cutting clean builds by 25%. Earlier, I shipped fintech payment and wallet infrastructure at Strike and native iOS products at Paddy Power Betfair, Yopeso, and Endava.
