PROFESSIONAL EXPERIENCE
Natife
iOS Developer | 2023 - Present
NDA product - part of a 15-engineer iOS team
• Owned delivery of event details, notes, attachments, and calendar event features, from clarifying requirements with
PMs and estimating work through implementation, backend API alignment, QA coordination, and release support.
• Built the iOS client for an AI assistant, covering UI, backend API integration, request cancellation, generation
history, errors, and mapping structured event data into editable form fields; AI processing ran on the backend.
• Contributed to incremental modularization with SPM and XCFrameworks: proposed approaches, migrated
assigned screens and features, and wrote architecture documentation while feature development continued.
• Optimized network requests and screen loading; resolved memory leaks and cross-screen data inconsistencies
using Xcode Memory Graph and the memory usage graph.
• Investigated support tickets and Firebase Crashlytics, fixing production issues and contributing to maintaining
~99.7% crash-free users.
• Implemented Deep Linking through custom URL parsing and routing to navigation destinations; added Amplitude
events with relevant screen data as event properties.
• Added and repaired unit tests with XCTest, Swift Testing, and Sourcery-generated mocks, isolating business logic
from networking and persistence.
• Streamlined the GitLab CI/fastlane merge-request pipeline by removing a redundant standalone build job already
covered by tests, reducing execution time by ~40%.
• Reviewed teammates' merge requests almost daily; helped debug issues, resolve conflicts, navigate the codebase,
and onboard colleagues to established project processes.

Heal Buddy - relaxation and sleep application
• Built an Apple Watch-style interactive sound grid and other custom SwiftUI components using MVVM; integrated
REST APIs, Kingfisher, and KeychainAccess.
• Implemented custom audio playback with AVFoundation, audio caching, and system music/media UI integration.
• Implemented a breathing-exercise feature with a timer, contextual user guidance messages, and Lottie-based
animation.
• Refactored a monolithic data layer that mixed networking, local persistence, and business logic into independent
architectural layers and components with clearer responsibilities. Used SPM and CocoaPods, with SwiftGen and
SwiftLint in the development workflow.
CHI Software
iOS Developer | 2022 - 2023
Diabetes tracking application
• Built an extensible URLSession and Combine networking layer with request plugins and multipart upload
support for a UIKit diabetes tracking app using MVVM and Coordinator navigation.
• Built collection interfaces with UICollectionViewCompositionalLayout and UICollectionViewDiffableDataSource;
integrated REST APIs, Keychain, AVFoundation, and SwiftGen.
Internal social application
• Contributed to an internal social app in an 11-person team with 4 iOS developers, using UIKit, MVP, Coordinator,
REST APIs, and SPM.
• Implemented authentication and local storage with Firebase, Google and Facebook SDKs, Realm, and Keychain;
debugged app issues.
Software Station
iOS Developer | 2021 - 2022
• Created custom UIKit components and animations with Core Graphics and UIBezierPath for an entertainment app.
• Implemented queued music playback with AVFoundation and AVQueuePlayer; used Alamofire and CocoaPods.

INDEPENDENT PROJECT
Glutopia
Independent iOS Engineer | Apr 2026 - Present
glutopia.app | Public TestFlight beta
• Independently own product scope, architecture, implementation, unit testing, Apple Developer configuration, and
TestFlight distribution for a diabetes management app.
• Build SwiftUI features with Observation, dependency injection, SwiftData, and HealthKit; use Swift Testing to cover
view models, state machines, repositories, persistence, and integration behavior.
• Implemented subscription purchase, restore, entitlement, and lifecycle flows with RevenueCat and StoreKit;
validated configuration and behavior in Apple Sandbox and TestFlight through App Store Connect.
