I started developing software 👩‍💻 before AI tools became common, which means my work is grounded in real engineering experience🧠. Today, I use AI as a powerful addition — not a shortcut — and can integrate AI-driven features into your Сross-Browser or Google Chrome extension when it truly adds value. 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 Store🛒 compliance. I enjoy turning ideas into production-ready extensions — from system architecture and UI implementation to a polished, pixel-perfect, high-performance result.🧩 💡 If you have an idea for a browser extension to 𝗯𝗼𝗼𝘀𝘁 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝘃𝗶𝘁𝘆, 🚀optimizing workflows, or enhance your website, my solutions will help you attract new customers, improve user experience, and 𝗴𝗿𝗼𝘄 𝘆𝗼𝘂𝗿 𝗯𝘂𝘀𝗶𝗻𝗲𝘀𝘀💹 by increasing engagement and efficiency. 🎯 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 cycle—from 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 𝗪𝗫𝗧 to support and manage both manifests simultaneously, ensuring reliable performance and easier maintenance. ✅️𝗞𝗲𝘆 𝗘𝘅𝗽𝗲𝗿𝘁𝗶𝘀𝗲 – HTML, CSS, JavaScript: Mastery of the core building blocks of web development, ensuring clean, maintainable code. – React and Next.j: Extensive experience in building high-performance, scalable web applications using these popular frameworks. – 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. – API Integration: Proficient in connecting front-end interfaces with backend services to deliver seamless user experiences. – Progressive Web Application (PWA): Skilled in developing high-performance PWAs that provide offline access and a smooth, app-like user experience. – Bootstrap & Responsive Design: Mastering responsive design with Bootstrap, creating adaptable and efficient applications for all screen sizes, from smartphones to desktops. – 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 extensions🧩, 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 Store🛒, avoids removal or rejection, and provides users with a stable, seamless experience. 👩‍💻 If you're looking for a developer who combines deep web development knowledge with specialized skills in browser extension creation, I’d be thrilled to collaborate and help bring your ideas to life. Simply click the "INVITE" button on my profile, and let's get started! 🤝 Somehow, OnlyFans became a related keyword to my niche.😅 I’ll take it as proof that Chrome Extensions are needed everywhere!

🚀 17+ years of professional experience 🚀 50+ successfully delivered enterprise & SaaS projects 🚀 9,500+ hours on Upwork of high-quality development delivered I'm a React Developer and Front End Developer with 17+ years of experience shipping enterprise and SaaS products across Logistics, Aviation, Real Estate, FinTech, and HealthTech. My work as a React Developer and Front End Developer covers the full frontend lifecycle - from Figma handoff and component architecture to deployment, bundle optimization, and Lighthouse audits. As a Front End Developer, I take full ownership of what I build, not just the code I commit. As a Front End Developer, I work with React JS, TypeScript, JavaScript, HTML5, and CSS3 daily. I implement reusable component libraries and scalable state management with Redux and Zustand. As a React Developer, I ensure cross-browser compatibility across all devices and browsers. I work with Next.js for SSR/SSG architectures deployed on AWS and Vercel, and integrate data visualization using Recharts and D3.js - standard tooling for a senior React Developer and Front End Developer. Performance and accessibility are non-negotiable for me as a Front End Developer and React Developer. I optimize for high Lighthouse scores, WCAG compliance, and fast load times for global audiences. Whether it's a conversion-focused landing page or a complex SaaS dashboard with real-time data, I build interfaces that are fast, accessible, and maintainable as a React Developer. This is the standard I hold as a Front End Developer on every project. Beyond pure frontend, I work as a Full Stack Developer when projects call for it. I've automated manual workflows by 50–70% through custom APIs and internal dashboards. As a Full Stack Developer, I integrate REST APIs and GraphQL services, and I've shipped B2C marketplaces with Stripe and PayPal for clients in Finance, Healthcare, and Insurance. Every engagement as a React Developer and Front End Developer is held to enterprise-grade delivery standards. Cross-platform mobile is part of my toolkit as a React Developer and Full Stack Developer. I build iOS and Android apps using React Native, delivering near-native performance for startups in the AI and IoT sectors. For backend logic I use Node.js, PHP, and Python — which I handle as a Full Stack Developer to complement my React Developer and Front End Developer frontend work. I align with distributed teams on coding standards, component architecture, ESLint/Prettier configs, and PR review processes. Large-scale dashboards, multi-vendor marketplaces, billing platforms, and subscription management systems are where I do some of my strongest work as a Front End Developer and React Developer. I build SEO-optimized Next.js applications with high Lighthouse scores. As a React Developer and Front End Developer, I help teams avoid future rework by delivering clean, scalable architectures that the next engineer can confidently extend. A well-structured codebase saves teams hundreds of hours. My domain experience as a Front End Developer and React Developer spans AI platforms, EdTech, Machine Learning tooling, fintech, and cybersecurity. As a React Developer and Front End Developer, I work end-to-end — from wireframe to production — and own the outcome. As a Front End Developer, I write code with consistent naming, clear component boundaries, and documented APIs so the next engineer can contribute without lengthy onboarding. What I bring as a React Developer and Front End Developer: - Component architecture: reusable libraries, design systems, Nx/Turborepo monorepo structure as a Front End Developer - State management: Redux, Zustand, React Query - chosen per project needs as a React Developer - API integration: REST, GraphQL, Stripe, PayPal, third-party SaaS services as a Full Stack Developer - Accessibility and performance: WCAG-compliant, Lighthouse-optimized as a Front End Developer - Cross-platform: React Native for iOS and Android as a React Developer and Front End Developer - SEO: server-side rendering, metadata, structured data as a React Developer using Next.js Looking for a React Developer or Front End Developer who delivers clean production-ready code? 9,500+ Upwork hours. 50+ shipped projects. Predictable delivery and long-term ownership. Clients hire me as a React Developer and Front End Developer for projects where the frontend is not just a UI layer but a core part of the product. As a Front End Developer, I've built analytics dashboards with real-time data, complex data-entry workflows, WebSocket-driven notification systems, and multi-step onboarding flows. As a React Developer, I think in terms of prop contracts, render performance, and state ownership - decisions that determine how painful the next feature will be to ship. If you're looking for a Front End Developer and React Developer who treats your codebase as their own, I'm the Front End Developer for the job. Let's build something great together.
