Enhance Your Browser Experience with Custom Extensions

I specialize in building bespoke browser extensions that add powerful functionality directly to your web browser. Whether it's for boosting productivity, automating repetitive tasks, scraping data, or integrating seamlessly with your existing services, I create secure and efficient solutions tailored to your needs.

🧠 Strategy & Planning

Defining the core purpose and functionality of your browser extension.

• Extension Concept & Feasibility Consultation: Defining the extension's purpose (productivity, scraping, UI enhancement) and planning core features, necessary permissions, and user workflows.
• Platform Targeting & Browser Support: Deciding on Chrome-first development or ensuring cross-browser compatibility (Edge, Firefox, Brave), along with the appropriate Chrome Manifest V3 or V2 strategy.
• User Experience Planning: Designing intuitive popup/interface wireframes and ensuring clear separation between background scripts and content scripts for optimal performance.

⚙️ Extension Development Services

Bringing your extension concept to life with robust and secure code.

• Custom Chrome Extension Development: Building with HTML, CSS, JavaScript (or TypeScript), and optionally using React or plain JS for popup UIs.
• Manifest V3 Configuration & Setup: Ensuring secure permissions, efficient background service workers, proper actions, and more, adhering to the latest browser standards.
• Core Extension Features: Implementing content script injection (to modify or read webpages), background processing, alarms/timers, popup UIs, sidebars, and context menu functionality.
• Storage and Syncing: Utilizing local, sync, or IndexedDB storage for seamless data persistence and synchronization across user devices.
• API & Backend Integration: Facilitating communication with external APIs or your own backend systems, including OAuth2, REST, and GraphQL integrations, with real-time data updates using WebSockets or polling.
• Advanced Capabilities: Implementing complex features such as web scraping and data capture, screenshot capture, screen readers, advanced DOM manipulation or UI augmentation, notifications, clipboard access, and efficient tab management.

🧰 Deployment & Maintenance

Ensuring a smooth launch and reliable ongoing performance for your extension.

• Publishing to Chrome Web Store: Guiding you through manifest and code validation, creating necessary Store assets (icon, screenshots, description), and navigating the publishing and approval process.
• Cross-Browser Packaging (Optional): Converting and testing your extension for compatibility with other browsers like Firefox or Edge, including polyfill support.
• Security & Performance Optimization: Implementing minification, permission hardening, CSP setup, and strategies to avoid memory leaks and handle large DOMs gracefully for optimal performance.
• Ongoing Support & Updates: Providing continuous bug fixes, manifest upgrades, new features, and metrics integration (e.g., Mixpanel, Amplitude) to keep your extension current and effective.
