FAQ
Can you fix or complete my AI-generated (Lovable/Bolt/Cursor) project?
Yes, this is a specialty. We audit the code, restructure it for production, add security and proper architecture, and hand back a maintainable app. Send the repo for a free assessment.
Can you build a complete SaaS MVP?
Yes — multi-user auth, Stripe subscriptions, admin panel, emails, and AWS deployment, end to end. The Premium package covers a launch-ready MVP.
I'm new to Fiverr — is my payment safe?
Completely. Fiverr holds funds in escrow until you approve delivery. We also work milestone-based on larger projects so you review progress at every stage.
Do you sign NDAs?
Yes, happily. Your idea and all project details stay confidential, and you own 100% of the code and IP.
What happens if bugs appear after delivery?
Premium includes 30 days of free bug-fix support. Ongoing maintenance retainers are available after that.
Which stack do you recommend — MERN or Next.js + NestJS?
Depends on your product's needs. We advise honestly after a short scoping chat; the plan is yours either way.
Can you work on my existing codebase?
Yes — features, refactors, performance work, or full takeovers. We start with a quick audit so you get an honest assessment first.
