Experience

Software Engineer

I am a Software Engineer passionate about solving problems through technology. I enjoy designing and developing web, mobile, and desktop applications, selecting the most appropriate tools for each challenge rather than limiting myself to a specific stack. I focus on building maintainable, scalable software that delivers real value, paying attention to both system architecture and the small details that enhance the user experience.
