WhatsApp engineering on Apple platforms, focused on media-rich product surfaces, expression experiences, mobile architecture, performance, platform integration, developer velocity, and AI-assisted engineering workflows.

• Led iOS delivery for WhatsApp’s redesigned Expressions Tray, a core chat surface that became the foundation for stickers, avatars, AI stickers, GIFs, Sticker Maker, and other media expression entry points across iPhone, Mac, and iPad.
• Drove cross-platform product work across iOS, Android, Mac, iPad, backend, identity, privacy, growth, support, and localisation teams, turning ambiguous product and platform requirements into shippable mobile experiences.
• Improved WhatsApp iOS architecture and developer velocity through modularisation, dependency reduction, lightweight feature playground apps, and faster build-run iteration in large-scale Apple-platform codebases.
• Worked across Apple platform infrastructure including Mac Catalyst, iPad, CarPlay, app extensions, Kotlin Multiplatform integration, build tooling, and AI-assisted developer workflows.

Worked on Revolut Reader, in-person merchant payments, Bluetooth LE hardware integration, and iOS SDK architecture for Revolut, Revolut Business, and POS use cases.

• Integrated Bluetooth LE card-reader hardware into first-party iOS apps for in-person merchant payments.
• Designed reusable iOS SDK architecture for device, payment, and transaction flows.
• Built SDK packaging, CI/CD, release, and publishing infrastructure for developer-facing mobile SDK distribution.

Senior iOS engineering with the Headspace product engineering team on a major app refactor toward server-driven content, reusable UI architecture, and more flexible content delivery.

• Contributed to Headspace’s migration from app-bundled meditation content to a server-driven content model.
• Built reusable Swift/RxSwift UI components for dynamic tabs, content surfaces, layouts, and navigation.
• Owned one of the main app tabs end-to-end, including API integration, UI implementation, navigation, state handling, and automated test coverage.

Built and led consumer mobile products in fast-growing startups across health, fitness, music, subscriptions, analytics, and audio/video creation.

• Built multiple 0→1 health and fitness apps across Objective-C and modern Swift codebases, including running, fitness, meditation, and sleep experiences.
• Led day-to-day iOS delivery for teams of up to 7 engineers, balancing product delivery, app quality, release readiness, and technical direction.
• Led iOS engineering for Rap Fame and shipped Rap-Z, a 0→1 audio/video creator app later featured by Apple several times.
