I'm a passionate and adaptable Software Engineer with a strong focus on front-end and mobile development. I currently work at Esti, where I’ve been part of a small but driven team transforming a rough MVP into a refined mobile experience using React Native and Expo. Being involved from the early stages has allowed me to contribute to both product direction and implementation, starting from Python-based prototypes and delivering a fully functional, user-friendly app now in beta testing. Before Esti, I was a Front-End Developer at 3step Web, where I worked across CRM projects, helped build a design system manager using JavaScript templating frameworks, and created mobile prototypes with React Native. I also helped develop internal AI-powered tools using OpenAI GPT-4. I love turning rough concepts into clean, intuitive interfaces and enjoy collaborating with teams to ship solid software.
