Good day!
We are a team of web developers with experience in creating complex eCommerce projects, including auction platforms, payment integrations, and internal balance dashboards. Your project is clearly defined, and we are ready to undertake full implementation: from architecture to launch in production.

1376 7 0 Thank you for the detailed technical task — it is clear, structured, and provides a complete understanding of the future functionality. We have experience implementing complex eCommerce solutions with custom logic, including auction systems, personal accounts, balances, and payment service integrations.
How can we help implement your project:
1. Architecture and platform
We recommend using Magento 2 as the core platform — this will allow you to have a stable online store base with a high level of security, scalability, and flexibility for implementing auction functionality.
We can also offer a separate auction module with a custom backend that does not affect the core system.
2. Implementation of the auction system
…
We will create a fully managed lot system with a timer, bids, and trading history
All actions will be recorded — both for the user and for the admin
We will ensure the logic for automatic notification of winners and processing of results
3. Payments and seller balance
We will integrate payment gateways (Stripe / Fondy / LiqPay — your choice)
After payment confirmation — automatic crediting of funds to the seller’s balance, considering the commission
Withdrawal requests via the account — with an admin control panel
4. Interface and UX
We will implement bilingual support (UA/EN, with the possibility of expansion)
Responsive modern interface that works equally well on all devices
We can additionally implement a feedback module, ratings, and chat between seller and buyer
5. Security and performance
Encryption of all critical data, protection against XSS/SQL injections
Speed optimization — caching, CDN, query optimization
Admin panel with the ability to view analytics on auctions, bids, and payouts
We have experience creating similar systems and can show examples in private discussions.
We are ready to propose a basic technical implementation plan and break the project into stages so you can monitor progress and launch.
Are you available to discuss this at a convenient time? After that — we will prepare a detailed project map and can start.

607 17 0 Hello! 👋
I propose creating a website based on the Laravel framework using a modern ready-made design template. This solution is slightly more expensive than WordPress or Wix, but it offers significantly broader possibilities for project development.
Such a website can be easily scaled in the future — you will be able to add new features and turn it into a full-fledged business management tool.
Full turnkey implementation, including custom design development by our team — approximately from $1500.
I will gladly answer questions and help select the optimal solution for your needs!
