Self-Employed

iOS Engineer

• I began my time at AppArt focusing on building robust, efficient code for the My DEDDiE App, using Swift and the latest iOS frameworks to deliver a smooth, reliable user experience. As the project evolved, I took on broader responsibilities, guiding development processes, mentoring engineers, and ensuring that technical decisions aligned with best practices and the long-term goals of the product.
• My work included driving key architectural decisions to ensure the app remained performant, maintainable, and scalable. I collaborated closely with cross-functional teams, including product managers, designers, and backend engineers, to translate requirements into clear technical specifications. I also designed and implemented new features, optimized performance through targeted refactoring, and resolved critical issues, all while maintaining GDPR compliance and meeting the demands of a highly regulated environment. Mentoring developers and conducting thorough code reviews was also a key part of my role, ensuring code quality and consistency across the team.
• One of my most significant contributions was the HEDNO Pioneers Green Energy Awareness project. I led the iOS implementation of this major sustainability feature, which allows users to track real-time renewable energy production from solar, wind, hydro, biomass, and other RES sources. Users can select specific geographical areas and timeframes for analysis, and view carbon reduction metrics in a clear, user-friendly interface. This update positioned the My DEDDiE App as a leader in environmental awareness and digital innovation, making green energy data easily accessible to citizens across Greece.
