I am a dynamic front-end developer with a specialization in React and GraphQL, and I bring a wealth of experience to the table. Over the past five years, I have crafted impactful B2C and B2B websites, demonstrating proficiency in React and GraphQL. In addition to my technical expertise, I have dedicated three years to mentoring junior developers through local tech workshops, fostering a collaborative learning environment within the community. As a seasoned web developer, I have excelled both independently and as a team player, contributing to projects across diverse technologies. Beyond my primary focus, I possess a strong foundation in SEO practices, ensuring the websites I build are not only visually appealing but also optimized for search engine performance. In the realm of content delivery and optimization, I have extensive experience with CDN technologies, specifically Amazon CloudFront and Cloudflare. Leveraging Amazon CloudFront, I've seamlessly integrated global content delivery into my projects, enhancing the speed and reliability of data transfer. With Cloudflare, I've implemented advanced security features, DDoS protection, and optimized content delivery, contributing to improved web performance. My commitment to delivering top-notch user experiences extends to design, where I seamlessly translate Figma/PSD mockups into responsive and user-friendly UIs. I adhere to best practices in accessibility and maintainable code standards, ensuring the long-term success of the projects I undertake. In addition to my core skills, I have a solid understanding of state management using Redux, employing techniques such as Redux Thunk and Redux Saga to handle asynchronous operations and complex state logic effectively. I am also well-versed in Redux Toolkit, streamlining the development process and enhancing code maintainability. To further diversify my skill set, I have expanded my proficiency to include Vue.js and Angular.js. Additionally, I am adept at static site generation, providing scalable solutions for web applications. In summary, I am a results-driven front-end developer with a multifaceted skill set, encompassing React, GraphQL, Redux, and additional frameworks, rooted in a commitment to excellence, mentorship, and continuous learning. My expertise in CDN technologies, particularly with Amazon CloudFront and Cloudflare, ensures optimized content delivery and enhanced web performance for the projects I undertake in the ever-evolving field of web development.
