FAQ
Q1: What makes your Pro package different from a basic extension developer?
At the Pro level, I deliver production-ready extensions built with TypeScript, React, and Manifest V3. Every project includes OAuth authentication, API integrations, unit testing, and clean architecture — not just simple scripts. You get enterprise-quality code ready for real business deployment.
Q2: Can you integrate my existing business tools like Google Workspace, Slack, or Notion?
Yes! I specialize in third-party API integrations including Google Workspace, Slack, Notion, Trello, and custom REST APIs. The Standard and Premium packages support up to 3 integrations. Additional integrations are available as a Gig Extra (+$40 each).
Q3: What is OAuth 2.0 and do I really need it?
OAuth 2.0 is a secure login method that lets users authenticate via Google, Slack, or other platforms without storing passwords. You need it if your extension requires user accounts, personalized data, or syncing across devices. It's included from the Standard package onwards.
Q4:Will the extension be safe to use with sensitive business data?
Yes. All Pro extensions use Chrome's secure storage API, HTTPS requests only, and token-based authentication. For projects requiring end-to-end encryption or NDA agreements, these are available as add-ons before the project starts.
Q5: Can you publish the extension to the Chrome Web Store?
Yes! Chrome Web Store submission is included in the Premium package ($500) and available as a Gig Extra (+$35) for Basic and Standard packages. Note: a one-time $5 Google Developer account fee is required on your side for publishing.
Q6: What happens if I need more features after delivery?
Revisions cover adjustments to existing features only. New features not included in the original brief will require a new order or a custom offer. I recommend discussing your full scope during the free discovery call before ordering to avoid this situation.
Q7: Do you provide a free consultation before I place an order?
Yes! I offer a free pre-order consultation via Fiverr chat, voice message, or async video (Loom) — no live call required. Simply share your requirements through any of these methods and I'll respond within 12 hours with a detailed project plan, timeline, and custom quote.
Q8: How will you deliver the final project?
You will receive a .zip file with the complete source code, technical documentation, and a README guide for installation. For Premium orders, I also provide a video walkthrough explaining the codebase and how to use the extension.
Q9: Can the extension support multiple users in my team?
Yes! Multi-user support is available in the Premium package ($500), including role-based access control (RBAC) for admin and regular users. For Standard orders, single-user OAuth authentication is included.
Q10: Is my project idea kept confidential?
Yes, I treat all project details with full confidentiality. If you require a formal NDA agreement before sharing sensitive business information, this is available as an add-on (+$15) and must be arranged before the project begins.
