About

Professional summary

I am a senior software engineer and product designer with more than 10 years of experience designing and developing mobile applications, alongside four years of Android development experience across Europe and the United States.

I specialize in native iOS development, cross-platform mobile products, web applications, and UI/UX design. I build reliable, user-focused solutions for industries including finance, agriculture, healthcare, and technology.

I have led small development teams and external partners, acting as a project manager and product owner while maintaining a hands-on engineering focus. I mentor developers, establish coding standards, and help shape scalable product architecture.

I am experienced in Swift, SwiftUI, Objective-C, Java, Python, Flutter, API integrations, data analysis, and visualization. My work includes modernizing legacy applications, developing B2B systems, and optimizing performance and payload efficiency.

I apply AI pragmatically in production products and have shipped browser-based tools using the Claude API, GPT, and Gemini, including a code assistant, meeting summarizer, resume analyzer, SOP generator, lifestyle coach, and adaptive tutor.

I combine engineering discipline with product design expertise, using data-driven improvements and strong UX principles to deliver accessible, effective digital products.
