Silence - meditations in Ukrainian

Worked as part of a promising startup, where I was responsible for the development, technical support, and scaling of a mobile application. Together with the team, I transformed business requirements into stable technical solutions.
Key technical tasks and achievements:
Analytics and metrics: Designed and implemented a flexible architectural wrapper (Facade pattern) for unified event logging. This allowed for parallel and seamless integration and sending of data to Mixpanel and Firebase for in-depth user behavior analysis.
Monetization and subscriptions: Fully configured the logic of in-app purchases for iOS and Android through RevenueCat. Integrated dynamic payment screens (Paywalls), enabling the marketing team to flexibly manage rates without the need to re-release the app in stores.
Backend & Firebase: Responsible for the development and optimization of the internal backend structure of the project based on Firebase. Developed new architectural data models and implemented cloud functions (Cloud Functions / Remote Config).
UI/UX and layout: Implemented a large number of new adaptive screens and complex interface elements based on pixel-perfect designs from Figma. Paid special attention to the smoothness of animations and the UI kit.
Quality and testing: Actively engaged in bug finding and fixing, conducted comprehensive functionality testing. Implemented the practice of code coverage with internal automated tests, significantly reducing the level of regression errors.
Product Mindset: Actively participated in product discussions, proposed technical improvements to optimize user experience (UX) and increase audience retention.
