Key Achievements:- App Redesign: Successfully led and executed a complete redesign of the mobile app in a short timeframe.- UI Kit & Widgetbook Integration: Added a UI kit and integrated Widgetbook, facilitating fast design reviews and enhanced testability.- Automated Testing & Reporting: Set up automated tests and reporting using Allure, improving code quality and reliability.- Team Leadership: Managed a team of four Flutter developers, coordinating development efforts and ensuring timely project delivery.- Workflow Optimization: Implemented workflows in YouTrack to streamline and optimize repetitive tasks.- System Integration: Set up integration between the corporate messenger and GitLab CI, enabling efficient issue status monitoring and streamlined delivery processes.Since October 2023, I have led a team of four mobile developers (including myself). My responsibilities included planning, establishing workflows and automations, mentoring, architectural design, and decomposing new features.I optimized the design review and iteration process by integrating own implementation of Widgetbook (eliminating the need to wait for builds to appear on TestFlight; instead, we can simply share a link) and by splitting the app into universal modules, such as UI Kit.

Key Achievements:- Project Recovery & Process Improvement: Took over a mobile app project from an outsourcing company in poor condition and established robust mobile app development processes.- CI/CD Implementation: Set up Continuous Integration and Continuous Delivery services in GitLab, enabling automatic builds and deliveries to QA for testing. Implemented an automatic release pipeline using semantic release.- Clean Architecture Setup: Structured the project following Clean Architecture principles to ensure maintainability and scalability.- Technical Documentation: Authored comprehensive technical documentation for complex services within the app to facilitate seamless backend integration and expedite onboarding of new team members.- Dynamic Content Integration: Proposed and implemented a dynamic content integration service using Remote Config for rapid iteration and content updates.- Chat Integration: Integrated chat support using WebSockets and a SaaS chat provider, enhancing real-time communication capabilities.- Complex Interfaces & Animations: Designed and implemented complex user interfaces and animations to improve user experience and engagement.- Performance Enhancement: Optimized app performance, resulting in faster load times and a smoother overall experience for users.Joined a team in November 2022. Was working on a migration from old backend to a new infrastructure in few months. After that worked on code quality and improvement of mobile project architecture. In parallel I supported video player private plugin for Flutter application.Worked on improving UX and new features for mobile application such as achievements system, secret materials, gamification of study process, etc.

Key achievements:- Technical Innovation: Proposed and implemented solutions to synchronize product states across pages, enhancing user experience and reducing latency.- Cross-Platform Expertise: Contributed to the successful rewrite of native Android and iOS apps to Flutter framework in six months, improving development efficiency and enabling faster feature deployment.- Quality Assurance and Testing Advocacy: Advocated for the adoption of unit and integration testing frameworks, ensuring robust development practices and reliable releases.- Performance and Code Quality: Actively contributed to improving application performance and code quality through suggestions and collaboration on legacy code refactoring.- Process Improvement: Offered ideas and recommendations to optimize CI/CD processes, streamlining release management and enhancing development productivity.- Architecture and Transition Support: Provided valuable insights and suggestions to facilitate the transition from native to Flutter, contributing to a more efficient and scalable application architecture.I participated in working on new features including native and flutter development to February 2022.Rewrote two native projects (Android and iOS) to Flutter framework and published it to stores.I participated in making architecture decisions and offered ideas to make rewrite from native to Flutter easier and faster.Full application rewrite took half-year. In final we had robust application ready for new featuresWorked on architecture improvements and integration of new features.

Key achievements:- CI/CD Setup: I set up CI process to automate release process- Fast setup and development: Made application from scratch using Flutter in one month- Backend Development: Participated in back-end development- Architecture Design: I was making architectural decisions to make application stable and flexibleI amplified mobile-side codebase written with Flutter, adjusted project structure to Clean Architecture, covered code with tests.I had set up CI/CD pipelines for automatic builds and deploys in Play Market and App Store using CodeMagic platform.Also began to contribute to back-end services built in Python (Django REST). In the last 3-4 months replaced lead back-end developer.Project had shut down due to profit reasons

Developed mobile front-end MVP with Flutter framework.I actively used BLoC pattern with DI - koin.dart.

Key achievements:* I learned multiple technologies such as: React, Flutter, VueJS* I learned clean architecture principles to make my work more flexible and stable* I actively read and researched different practices during freelance work to be competitive worker on a marketDeveloped several websites, web-apps, browser games and MVPs for different clients using React, VueJS, Flutter.
