What I'm looking for

I am looking for a collaborative environment that fosters innovation and growth, where I can contribute to impactful projects and continue to develop my skills.

I'm a Senior Frontend Developer with over 4.5 years of experience in creating fast, intuitive, and user-friendly web applications. My expertise lies in leveraging technologies like Next.js, React, and TypeScript to transform complex ideas into simple, engaging experiences. I thrive on collaboration, working closely with designers and product teams to ensure that the end product is not only functional but also enjoyable for users.

Throughout my career, I've successfully led significant projects, including a large-scale legacy project where I improved performance by migrating from Webpack to Vite, drastically reducing build times. My proactive approach has allowed me to identify and resolve critical issues swiftly, enhancing the overall developer experience. I am passionate about continuous learning and staying updated with the latest technologies to deliver high-quality solutions.
