Project history
As the sole iOS Developer at Awwt Company, I am at the forefront of creating an innovative application that transforms the way users interact with art. Leveraging the latest in VR technology, this app offers a unique 3D browsing experience that allows art enthusiasts to explore a diverse array of artworks.
Technology:
→ SwiftUI: For UI design, enhancing the app's layout with declarative syntax and real-time previews.
→ PostHog: Integrated for advanced analytics and user behavior insights.
→ Stripe SDK: Manages secure payment processing for artwork purchases.
→ ARKit/RealityKit: Powers immersive AR experiences, allowing users to preview artworks in their space.
→ Apple's OpenAPI Generator: Automates networking code generation from the OpenAPI specification for efficient backend communication.
→ async/await: Streamlines asynchronous tasks in networking and UI, boosting app responsiveness.
Key Features:
→ Advanced Filtering: Simplifies artwork searches by size, orientation, and name.
→ Artwork Details: Offers comprehensive information on each artwork.
→ Virtual Reality Integration: Visualizes artworks on home walls using VR.
→ E-commerce Capability: Enables direct purchases within the app.
This role involves extensive coordination of project requirements, implementation of cutting-edge iOS technologies, and continuous enhancement of user experience, ensuring the delivery of a high-quality product that meets the artistic and practical needs of modern art buyers.

Technology:
- SwiftUI: Refactored an app that it will be based only on SwiftUI
- XCTest: Introduced UI and unit testing in project
- CI/CD: I have set up Xcode Cloud pipelines for distributing builds using TestFlight
- async/await for better handling asynchronous tasks
- URLSession for network communication with RESTful backend
- VisionKit for document scanning
- PDFKit for document preview
- The codebase designed in the way, that it will be easy way to support white-label products. One base source code used for multiple mobile applications. With this app, customers can scan health-related documents, upload them for review to health institutions and get review status about the document validation progress. To implement these functionalities it was used: SwiftUI, Swift, Combine, async/await, VisionKit, Networking, PDFKit, UIKit and other.

Technical:
- Swift, SwiftUI, Combine, and UIKit were used for user interface development
- CoreBluetooth used to connect and communicate with BLE (Bluetooth) devices
- McuManager and CBOR were used for communication with BLE device
- FHIR (Fast Health Interoperability Resources from HL7) integration into iOS app using RESTful API
- CoreData for saving users' data
- HealthKit for reading electrocardiograms from the iOS device
- Health data representation: ECG, heart rate and step counts
- SCRUM master as for iOS and Android projects
- I was developing health app (MyHealth). An app was responsible for pairing with medical device using Bluetooth. User sign-in and authentication using AWS Cognito. Communication with FHIR* supported backend. Data persistence using CoreData. Medical data (electrocardiograms (ECG), heart rates and steps) visualization in the app. As well I have worked as SCRUM master. I have been preparing and creating technical tasks for iOS and Android Teams.
