👋 About Me

Mobile app developer who led a 4-person team and implemented CI/CD pipelines and a code review process that reduced manual testing time by 50%. Strong native Android development background with expertise in platform-specific optimizations.

With an AI master’s degree and LLM integration experience, I can effectively integrate generative AI features into mobile applications. Reduced inappropriate recipe generation rates from 85% to 12% by implementing prompt engineering and a custom validation model.

Successfully deployed Flutter-based apps to Play Store and App Store with features like Firebase backend integration, Clean Architecture implementation, and real-time data synchronization. Achieved a 40% reduction in AI generation time and 35% reduction in API costs through performance optimization.
