FAQ
What do you need from me to start?
Access to your codebase (GitHub preferred), API keys, and a brief of what the integration should do.
What if something breaks after you deliver?
I stand behind my work. If anything I built stops working due to my implementation, I'll fix it for free. I also test everything in a sandbox environment first, so by the time you see it, it has already been validated.
Is it safe to give you access to my PayPal or Stripe account?
Yes, I only need your API keys, not your login password. API keys are separate credentials that can be revoked at any time. I'll walk you through how to create them safely, and you can delete them after the project if you want. I never store or share your keys.
Do I need a developer on my team to use what you build?
No. I deliver everything ready to use. If you have an existing website or app, I'll plug everything in directly. If you ever need to make changes later, I provide clear documentation so any developer (or even you, with guidance) can manage it.
Which frameworks do you support?
React, Next.js, Node.js, Laravel, Django, Flutter, React Native, message me if you have something else.
Do you set up test and live environments?
Yes, I always set up sandbox testing first, then move to production after your approval.
Will my customers' payments go directly to me?
Yes, payments go straight to your Stripe or PayPal account. I am just the person who sets up the connection. I have no access to your funds, and nothing passes through me.
I'm not sure exactly what I need. Can I explain my idea and you figure it out?
That's completely fine, most of my clients start that way. Just message me and describe what you're trying to achieve in plain language, like "I want customers to pay on my website" or "I want to send automatic emails when someone signs up." I'll figure out what integrations are needed.
Are there any extra costs besides your fee?
My fee covers the setup work only. Stripe and PayPal charge their own transaction fees (typically around 2.9% + $0.30 per transaction), that's paid directly to them, not to me. There are no hidden fees on my end.
