PROFESSIONAL EXPERIENCE
Natife
iOS Developer | 2023 - Present
Selected NDA project - part of a 15-engineer iOS team
- Owned the delivery of event detail screens with notes and attachments, as well as calendar event
features; clarified requirements with PMs, estimated tasks, agreed on API contracts with backend
engineers, and coordinated testing with QA.
- Implemented the iOS interface and application logic for an AI assistant that converted user descriptions
into structured event data and populated the corresponding form fields; handled backend integration,
request cancellation, history management, and error handling.
Engineering contributions across projects
- Contributed to incremental modularization using SPM and XCFrameworks across different projects;
proposed architectural approaches, migrated existing screens to a shared architecture, and authored
architecture documentation in collaboration with the team while feature development continued.
- Standardized screen architecture and removed unused code with Periphery and SwiftLint, contributing to
faster builds, smaller application binaries, and faster development of new screens.
- Optimized network requests to reduce screen loading times and resolved memory leaks and data
inconsistencies across screens; investigated production issues using support tickets and Firebase
Crashlytics.
- Helped introduce Sourcery-generated mocks to isolate business logic tests from networking and
persistence; added unit tests for new features and fixed failing tests.
- Removed a redundant clean build from the fastlane CI pipeline, shortening execution time and providing
faster feedback on changes.
- Reviewed code and helped teammates debug issues and implement features.

PROFESSIONAL EXPERIENCE CONTINUED
Natife - Continued
Heal Buddy - relaxation and sleep application
- Developed new screens using SwiftUI and MVVM, including a custom audio player interface backed by
AVFoundation and a custom grid of sound elements.
- Integrated REST APIs and third-party libraries, including Kingfisher and KeychainAccess.
- Added Lottie animations to the application's interface.
- Set up project environments, managed dependencies with SPM and CocoaPods, and configured
SwiftGen and SwiftLint.
CHI Software
iOS Developer | 2022 - 2023
Diabetes tracking application
- Designed and implemented an extensible networking layer using URLSession and Combine, with
request plugins and multipart upload support.
- Built UIKit interfaces using UICollectionViewCompositionalLayout and
UICollectionViewDiffableDataSource.
- Implemented Coordinator-based navigation, local storage, and authentication, integrating REST APIs,
Keychain, and SDKs from Firebase, Google, and Facebook.
Software Station
iOS Developer | 2021 - 2022
Entertainment application
- Created and animated custom UIKit components using Core Graphics and UIBezierPath.
- Implemented queued music playback using AVFoundation and AVQueuePlayer.

INDEPENDENT PROJECT
Glutopia
Independent iOS Engineer | Apr 2026 - Present
Diabetes management app with a diary, dashboards, and analytics.
glutopia.app | Public TestFlight beta
- Independently built and released the application as a public TestFlight beta, owning product scope,
architecture, implementation, testing, release configuration, and distribution.
- Implemented modular SwiftUI features using Observation and dependency injection, with SwiftData for
persistence and HealthKit for Apple Health synchronization.
- Wrote unit tests with Swift Testing to validate state machines, view models, repositories, persistence,
HealthKit integration behavior, and architectural boundaries.
