FAQ
What technologies do you work with?
I specialize in: - Frontend: React, JavaScript (ES6+), HTML5, CSS3 - Backend: Node.js, Express.js, RESTful APIs - Database: PostgreSQL - Auth: OAuth 2.0, JWT, session management - Hosting: Vercel, Heroku, AWS (basics), Hostinger - Payment: Stripe, PayPal, Square integrations
What access do you need to fix bugs?
Typically I need: - GitHub repository access (or code files via Fiverr) - Error logs or screenshots showing the bug - Ability to reproduce the bug (locally OR staging environment access) - For production bugs: Read-only access to logs/monitoring
How long does debugging usually take?
It varies by complexity: - Simple bugs (typos, missing imports, CORS): 1-2 hours - Medium bugs (logic errors, state issues, API problems): 2-4 hours - Complex bugs (race conditions, performance, security): 4-8 hours Delivery times in my packages include buffer for testing and documentation.
What if you find multiple bugs during debugging?
Great question! Here's my process: 1. I focus on the bug you ordered a fix for 2. If I discover related issues, I document them 3. I message you with findings and recommendations 4. You decide: Fix now or later I never leave critical issues unfixed, but I respect package boundaries.
What if you can't fix my bug?
For if I couldn't fix: - I refund immediately (usually within 4 hours of starting) - Explain why (e.g., "Requires iOS expertise I don't have") - Recommend next steps or other sellers Message me first—I'll assess for free and tell you within 2 hours if I can help.
Do you provide explanations of the fixes?
Yes! Every delivery includes: ✓ The fix itself (obviously) ✓ Explanation of root cause (what was wrong) ✓ Prevention tips (how to avoid similar bugs) ✓ Code comments explaining changes ✓ Testing notes showing what I verified
