FAQ
Which browsers do you develop for?
I build extensions for Chrome, Firefox and Edge, all compliant with the latest Manifest V3 requirements. Let me know your target browser(s) when we discuss your project.
How long will my project take?
Timeline depends on complexity. Simple extensions can be done in a few days; more advanced projects (automation, APIs, payment integration) may take longer. I'll give you an accurate estimate after we discuss your requirements.
Will I receive the full source code?
Yes. Once the project is complete and delivered, you receive the complete, clean source code with no restrictions on ownership.
I'm not a technical person, can you still help me?
Of course. Just describe what you want your extension to do in plain terms and I'll handle all the technical details.
Can my extension integrate with APIs like OpenAI, Gemini or my own backend?
Yes, I regularly integrate third-party and custom APIs into extensions. Just have your API details/documentation ready to share.
Can you add login, licensing or payment features so I can sell my extension?
Yes, I build monetization-ready extensions with authentication, licensing and payment system integration.
Can you publish the extension to the Chrome Web Store / Firefox Add-ons store for me?
I can walk you through the submission process, but the extension must be published under your own Chrome Web Store / Firefox Add-ons developer account. This keeps you as the rightful owner of the listing, avoids future access issues and lets you manage updates independently.
Do you offer ongoing support or maintenance after delivery?
Yes, I offer post-delivery support and can set up an ongoing maintenance arrangement if you need regular updates or bug fixes.
