CV

Hey there! I specialize in building TypeScript-based web applications. My primary focus is on creating robust, scalable and user-centered websites. I work with frameworks like React.js and Vue.js, along with Node.js and APIs based on REST or GraphQL – deployed on AWS, DigitalOcean or Netlify. I've also worked with Azure AI services, leveraging OpenAI models to bring intelligent, language-driven features into web applications.

I combine strong technical skills with a deep understanding of UX and performance best practices, ensuring every project is fast, intuitive and enjoyable to use.

My work is informed by solid design fundamentals, and I'm comfortable collaborating with designers and working directly in tools like Figma to bridge the gap between design and development.

I’m eager to explore new technologies and integrate them into existing development stacks or build online experiences from scratch. I enjoy working in agile teams, mentoring other developers and collaborating with stakeholders across departments to deliver impactful, user-focused solutions.
