I have developed an intuitive waste bin collection reminder app using MVVM design pattern, SwiftUI, SwiftData, and UserNotificationCenter.- Designed app using SwiftUI, which helped reduce overall development time.- Integrated SwiftData for efficient data management, increasing performance by 16% for faster navigation and UX. - Implemented the MVVM design pattern, fortifying the code architecture for maintainability.- Manually conducted A/B testing for UI/UX improvements, leading to visible increase in user satisfaction. - Published the app on the App Store: My Waste, making it accessible to a wide user base (https://shorturl.at/iYZ02).

Health app- Implemented push notifications, boosting app functionality and increasing user engagement nearly by 25%.- Collaborated effectively with cross-functional teams in an Agile environment, fostering teamwork and timely product delivery.- Engineered UI programmatically, using SnapKit, resulting in a 15% increase in user satisfaction after the Beta test. This implementation led the app to a 10% reduction in user interface-related issues.- Spearheaded the incorporation of advanced technologies such as MVVM-C, RxSwift, and Firebase into iOS applications, reducing API response times by a few per cent.- Utilised Git for version control, ensuring organised and collaborative development processes.

Ucheba.ru is a large Russian educational technology company with 2+ million active users every month. They provide information services for university applicants, a CRM system for educational institutions and more resources for exam preparation.In 2020 Ucheba.ru got investment. The main purpose was to update existing products and launch new ones.I was hired as the only QA Engineer for setting up QA processes, delivering quality and supporting the creation of new products. In two years, we have launched an online school for exam preparation, a CRM system for educational institutions (which helps clearly communicate with applicants), updated the design and logic of the information service by 80% and conducted many online events to popularise science and higher education among school students. I also:• Used Python for making automatic API tests for the company's API for faster-conducting regression tests.• Used SQL for interacting with database (PostgresSQL, MySQL etc.).• Conducted functional and non-functional testing of frontend and backend.• Collaborated with developers, designers, and business team daily. I was involved in sprint planning, prioritizingtasks, and daily morning sync-ups.• Promote software testing standard methodologies.• Used Postman for working with API. • Used developer tools and Charles for testing web.• Created test documentation and updated it regularly.• Monitored metrics and logs on Grafana and Greylog for clear understanding work system.• Interacted with databases for checking or changing data.Having the experience of working in a start-up, I learned to work independently, own decisions, conduct end-to-end test processes and work well in a fast-paced environment. At the same time, I believe in transparent communication and can collaborate effectively with a wider team to drive the best results possible.
