About Me

Front End Developer

With over 5 years of experience in software development, I specialize in creating high-performance front-end applications across web and mobile domains. My expertise spans building React micro-frontends, React Native apps, and Android applications, with additional experience in machine learning, C#, Java, and SQL/MongoDB.

I'm passionate about clean code, modern development practices, and delivering pixel-perfect user experiences. In my current role, I've developed a React component library using Storybook for interactive prototyping and organization-wide consistency, and worked on internal portals, customer-facing software, and micro-frontends. In my free time, I've built React/Next.js websites and React Native apps for clients as a freelancer. I'm always eager to tackle new challenges and stay current with emerging technologies.

I believe in continuous learning and the power of collaboration to create amazing digital experiences that users love.
