At Surfboard Payments, I spearhead mobile and frontend engineering for CheckoutX, a contactless payment platform deployed across Sweden, Finland, Norway, Denmark, and Ireland. I architected payment workflows integrating Klarna, Swish, digital receipts, and merchant cash reconciliation.
I engineered an offline-first transactional engine with encrypted local storage, enabling card processing during intermittent network drops. I also connected Flutter to NFC hardware and POS peripherals through Kotlin and Swift Method Channels.
At Surfboard Payments, I parallelized bootstrap API calls to reduce terminal cold-start latency and maintained crash-free session stability tracked through Firebase Crashlytics. I automated release pipelines across Google Play, the App Store, and payment terminals.
Previously, at CMOTS Internet Technologies Pvt. Ltd., I developed Capitaline Newswire, a financial intelligence app with real-time market feeds and interactive stock charts. I also implemented local caching and optimized UI frame rates.
