FAQ
Will my extension be Manifest V3 compliant for 2026?
Yes. I build all tools with Manifest V3 standards to ensure security, high performance, and 2026 compatibility. This prevents "unsupported" warnings and ensures your tool remains functional on the Chrome Web Store. I focus on future-proof development.
Can you integrate AI like GPT-4o or Google Gemini?
Definitely. I specialize in adding AI & LLM integrations directly into the browser. Whether you need a smart Gmail assistant, content detection, or an AI agent to automate thinking, I connect your extension to OpenAI or Gemini APIs for advanced automation.
How do you handle complex scraping (Amazon/Zillow)?
I use advanced bypass techniques for AWS WAF or Captcha. I have built high-fidelity tools like Amazon Slot Trackers and Zillow Scrapers that sync data to Google Sheets, CSV, or custom SaaS dashboards. I ensure reliable data mining with anti-bot protection.
Do you help with the Chrome Web Store approval?
Yes. I build extensions with Google’s strict security review policies in mind. With a 100% approval rate over 100+ projects, I handle the technical side to ensure your extension gets approved quickly without silent rejections or policy violations.
Can you build a Full-Stack extension with a UI?
es, I am a Full-Stack developer. I use React for modern UIs (including Side Panels) and Node.js/Firebase for backends. This is perfect for complex tools like Crypto Cashback, Hiring Automation, or SaaS products that require user authentication and databases.
Why should I message you before ordering?
Every automation project is unique. Messaging first allows me to provide a 5-minute technical breakdown and a realistic timeline. This prevents scope issues and ensures I select the right tech stack (React, GAS, or Node.js) for your specific business goals.
