I started as a developer at a microfinance organization, which later transformed into a full-fledged bank. During my time there, I went from supporting an MFI app to participating in the development of a large-scale mobile banking product with millions of users. I designed and implemented a new application architecture (MVVM + Combine + Coordinator), which increased stability and simplified scaling. Implemented a modular project design using Swift Package Manager and internal SDKs. I set up a CI/CD pipeline (GitLab CI + Fastlane) for automated building, testing, and deployment to TestFlight and the App Store. Implemented a multi-tier environment system (Dev / Test / QA / PredProd / Prod) with flexible configuration management and backend endpoints. I actively wrote unit tests in XCTest, achieving 20%+ coverage of key modules. Worked with AppCenter, Firebase, Adjust, Crashlytics, and AppMetrica for analytics and stability monitoring. Optimized performance and reduced cold start time by 40%. Developed screen flows for KYC, authorization, payments, P2P transfers, transaction history, and more. Collaborated with the backend team (REST / GraphQL / WebSocket) and participated in API design. Mentored junior developers, conducted code reviews, and contributed to the development of internal code standards and CI scripts.

• I was developing two mobile applications from scratch. The application involves working with the user's geolocation, notification, web-socket to receive notifications for the user within the application, default authorization and apple/facebook/google authorization. Work was also carried out with the Apple map, with the help of which the user could see his location and partner, as well as find his way to him. The application is completely client-server. Each user also has their own unique QR code. With which a partner can scan it. • The second application is intended exclusively for project partners. The main functionality is to scan the client's QR code using the camera and write off the coupon. There is also a history of redeemed coupons and current coupons.

I developed an MVVM architecture using the RxSwift library. I configured interactions between schemas and targets and linked them to TestFlight. I developed an in-app database using Core Data.

Manually tested the written functionality of other developers. I checked the code they wrote. Developed MVC + DI architecture. Worked with queries and writing a filter for response data.
