Kamyanske, UkraineĀ - 1:04 am local time
I am a Chrome Extension Developer with 8+ years of experience whose expertise goes beyond standard Front End and Back End development. My work is deeply grounded in browser extension architecture, including hands-on experience with Manifest V3 configuration, permissions, background/service workers, and Chrome Web Storeš compliance. I enjoy turning ideas into production-ready extensions ā from system architecture and UI implementation to a polished, pixel-perfect, high-performance result.š§©
š” If you have an idea for a browser extension to šÆš¼š¼šš š½šæš¼š±šš°šš¶šš¶šš, šoptimizing workflows, or enhance your website, my solutions will help you attract new customers, improve user experience, and š“šæš¼š šš¼ššæ šÆššš¶š»š²ššš¹ by increasing engagement and efficiency. šÆ
My passion lies in bringing concepts to life, meticulously crafting each element from layout to the final, pixel-perfect product with high-quality design and performance.
I have experience in the full development cycleāfrom designing and building the product to successfully publishing it on the Chrome Web Store. With a solid understanding of both Manifest V2 and Manifest V3, I develop efficient, cross-browser extensions that work seamlessly in Chrome, Firefox, and even IE. These extensions can be built using pure JavaScript or React, with a preference for React to leverage its modular and scalable architecture.
Aware of the challenges in maintaining compatibility across multiple browsers, I utilize šŖš«š§ to support and manage both manifests simultaneously, ensuring reliable performance and easier maintenance.
ā ļøšš²š šš š½š²šæšš¶šš²
ā HTML, CSS, JavaScript: Mastery of the core building blocks of web development, ensuring clean, maintainable code.
ā React and Next.j: Extensive experience in building high-performance, scalable web applications using these popular frameworks.
ā Chrome API, Manifest V3 and Manifest V2: Mastery in building and upgrading cross-browser extensions using Chrome API, Manifest V3 and V2, ensuring seamless compatibility and adherence to modern standards.
ā API Integration: Proficient in connecting front-end interfaces with backend services to deliver seamless user experiences.
ā Progressive Web Application (PWA): Skilled in developing high-performance PWAs that provide offline access and a smooth, app-like user experience.
ā Bootstrap & Responsive Design: Mastering responsive design with Bootstrap, creating adaptable and efficient applications for all screen sizes, from smartphones to desktops.
ā Webpack and Babel: Skilled in optimizing applications to ensure efficient bundling, faster load times, and modern JavaScript compatibility across different browsers. Expertise in reducing bundle size and improving performance for seamless user experiences.
In addition to building new extensionsš§©, I specialize in migrating existing extensions from Manifest V2 to Manifest V3. Since Chrome Web Store has discontinued V2 support, I help ensure your extension remains compliant with current browser policies while preserving existing functionality and performance. This migration keeps your extension live in the Chrome Web Storeš, avoids removal or rejection, and provides users with a stable, seamless experience.
