FAQ
Q1: What is included in the Basic package?
The Basic package is designed for small tasks — fixing bugs, adding minor features, or building/fixing API endpoints in an existing MERN app. It covers up to 2 pages and is delivered in 7 days. It's not suitable for building a full application from scratch.
Q2: Is Standard suitable for a brand new web app?
Yes. The Standard package covers a full redesign or new build of up to 6 pages by a full stack front-end developer. It's ideal for businesses that need a complete, optimized web application with clean UI and backend integration.
Q3: What exactly does the Premium package include?
Premium is our full custom development tier — we build your entire product from scratch according to your specifications. Up to 10 pages, 30-day delivery, unlimited revisions, and full stack coverage including frontend, backend, database, and deploy
Q4: Will I get the full source code?
Yes, absolutely. All packages include complete source code ownership. No subscriptions, no hidden fees, no lock-in.
Q5: Can you work on my existing MERN codebase?
Yes — especially in the Basic and Standard tiers. Share your GitHub repo before ordering and we'll review it to confirm compatibility and scope.
Q6: Do you handle deployment?
Deployment is included in Standard and Premium packages. We support Vercel, Render, Railway, DigitalOcean, or any VPS. We also configure custom domains and SSL certificates.
Q7: How do you communicate during the project?
We send regular progress updates via Fiverr messages. For Standard and Premium projects, we can set up a shared Trello or Notion board so you have full visibility at all times.
Q8: My project is bigger than the Premium package — can you handle it?
Yes. We take on large-scale projects via milestone-based custom offers. Message us with your full requirements and we'll structure a plan that fits your timeline and budget.
Q9: Do you sign NDAs?
Yes. Client confidentiality is a priority. We'll sign an NDA before the project begins upon request — no questions asked.
Q10: Why is there such a price difference between Basic and Standard?
Basic is scoped for isolated tasks on existing codebases — a few hours of targeted work. Standard involves full application development with design, frontend, backend, and integration — a significantly larger scope of work. If you
