What I'm looking for

I am looking for a remote position that fosters collaboration, innovation, and growth opportunities.

As a Senior MERN Stack Developer with over 7 years of remote work experience, I specialize in building scalable web and mobile applications. My expertise lies in React, Node.js, TypeScript, and MongoDB, and I thrive in collaborative Agile environments. I have a proven track record of delivering high-quality features on time, optimizing front-end performance, and maintaining clean, maintainable code.

In my current role at Shopify, I developed merchant-facing applications using React and Next.js, significantly improving load times and reducing UI bugs. My previous experience at Revolut allowed me to contribute to both frontend and backend services, launching multiple core product updates within tight deadlines. I am passionate about leveraging modern development workflows and tools to enhance productivity and deliver exceptional user experiences.
