About this gig
I create powerful, custom browser extensions that transform how you interact with the web. As a dedicated extension specialist (not a jack-of-all-trades developer), I focus exclusively on mastering browser extension development.
What sets my services apart:
- Expert in Chrome, Firefox, Edge, and Safari extension architecture
- Solutions ranging from simple time-savers to complex API integrations
- Custom algorithms tailored to your specific workflow needs
- Clean, efficient code that won't slow down your browsing
Whether you need a one-click text copier, an intelligent form autofiller, a data scraper with custom filters, or a sophisticated tool integrating multiple APIs I deliver polished, professional extensions that work seamlessly.
Unlike generalist developers who build everything from mobile apps to websites, my singular focus on browser extensions means deeper expertise, faster delivery, and solutions built specifically for browser environments.
Ready to enhance your browsing experience or streamline your team's workflow? Let's discuss how a custom browser extension can save you time and eliminate frustrating manual tasks.

FAQ
What browsers do your extensions work with?
I build extensions compatible with Chrome, Firefox, Edge, and Safari. During our initial discussion, we'll determine which browser is a priority for your project.
Can you modify existing extensions?
Yes! I can enhance, debug, or add new features to your existing extensions. I'll first review the code to ensure compatibility and then provide options for improvement. Please bare in mind it really does depend how good the developer was who originally coded for how long it will take us to work out.
What information do you need to get started?
The most important details are: 1) The specific websites where the extension will work, 2) The exact functions you need it to perform, and 3) Any design preferences you have. Don't worry if you're not sure about technical details - I'll guide you through the process.
