Currently, I'm leveraging my expertise to develop cross-platform applications with React Native. This enables me to deliver a consistent experience across Android, iOS, and the web from a single codebase.
My English proficiency is at the Upper-Intermediate (B2) level, which allows me to communicate effectively in professional and academic environments. I maintain my skills by regularly consuming technical content and collaborating with international colleagues.
