At Performance Golf, I designed multiple UX flows from scratch and refactored payment and upsell systems to support pricing experiments. I also integrated a marketing SDK for remote experiments and reduced the app bundle size by more than 60%.
At Solvd, Inc., I revamped a client's payment solution across its iOS client and backend, resolving an issue that left approximately 10% of paying users without purchased services and boosting yearly revenue by 10–15%. I also migrated approximately 25% of a legacy codebase from Objective-C to Swift and improved architecture to reduce maintenance time by 40%.
Earlier, I engineered iOS applications as a self-employed developer and worked as a Junior iOS Developer at OrangeSoft. My experience includes Swift, Objective-C, iOS architectures, payment systems, and performance optimization.
