Hello, Julia! Based on your request, I have made the following conclusion:

You need a reliable, fast, and user-friendly website with payment options in three currencies, accurate delivery calculations, and a cashback bonus system so that customers can easily make purchases and return again.

I am your partner who will not just connect payment systems and delivery services, but will do it in such a way that the website operates smoothly, loads quickly, and generates real orders.

1. Connecting PayPal, Stripe, LiqPay, WayForPay with support for USD, EUR, UAH currencies and automatic conversion
2. Integration of Nova Poshta and Ukrposhta APIs with branch selection and automatic cost calculation
3. Full testing: payments, delivery, cart, responsiveness, cross-browser compatibility, form protection, speed
4. Checking and configuring cashback system with all features: accrual, usage, history, notifications
5. Transfer of access and clear instructions for self-management of the website
6. Support after launch (1 month free + further support by agreement)

Methods (How I will do it):

I will connect all payment modules according to the technical specifications, setting up commissions and multi-currency support via OpenCart module

I will integrate delivery services through their APIs, enable branch selection, and auto-load costs in the order form

I will conduct comprehensive testing on all popular devices and browsers, check SSL, reCAPTCHA, and optimize speed

I will set up the cashback system with all necessary functions and customer notifications

I will prepare instructions and transfer all access details

I. Analyze the technical task
II. Connect payment systems and delivery services
III. Set up multi-currency and conversion
IV. Test all functions on different devices and browsers
V. Configure cashback system and verify its operation
VI. Transfer the website with instructions and access details
VII. Provide support after launch

I work on a freelance marketplace, always available, without agency bureaucracy — quickly, efficiently, and transparently. Expand
