CV
Hey there! I specialize in building TypeScript-based web applications. My primary focus is on creating robust and user-centered websites. I am well-versed in utilizing frameworks like React.js and Vue.js, along with Node.js and APIs based on REST or GraphQL – running on infrastructure provided by AWS, DigitalOcean or Netlify.
I've also worked with Azure AI services, leveraging OpenAI models to bring intelligent, language-driven features into web applications.
In addition to my technical proficiency, I have a strong understanding of UX (User Experience) principles and web performance. I prioritize creating seamless and intuitive experiences for end users while ensuring the application's efficiency.
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 am always eager to explore new technologies and incorporate them into existing development stacks or create from-the-scratch online experiences. I enjoy working in agile teams, mentoring other developers and continuously improving the team's development processes.
