[ ENGINEERING STANDARD CMS ]

How we transform standard CMS into fast, secure, and managed commercial platforms

Most CMS websites suffer from mindless installation of dozens of third-party plugins. This leads to catastrophic slowdowns, regular virus infections and constant conflicts during updates. Our engineering approach is custom lightweight themes without slowdown builders, clean MySQL database structure, only verified system modules, object caching integration with Redis and multi-level security framework.

✓ We sign an official contract with fixed price and development terms
✓ Warranty SLA support 90 days after the system is put into operation
✓ 100% transfer of intellectual property and source code of the project to the client

Cleanup of plugin trash

We are writing native modular code instead of heavy universal plugins, which reduces page size and server response time several times.

Comprehensive protection (Hardening)

Closing service endpoints, protecting configuration files, limiting login attempts and blocking SQL injections at the WAF level.

Ukrainian E-commerce ecosystem

We connect online payments (Monobank, LiqPay, NovaPay), cloud receipts via Checkbox/Vchasno, and automatic generation of Nova Poshta / Ukrposhta waybills.

Convenient administration (ACF Pro)

We create structured custom blocks: managers easily edit content, banners and products without risking accidentally breaking the layout.

[ FREQUENT QUESTIONS ]

Answers to questions from the client

Key details regarding terms, warranties, transfer of source code and the development process.

For most stores up to 10 000–30 000 items, WordPress with WooCommerce or OpenCart is an ideal choice: they have excellent support for Ukrainian payment systems (Monobank, LiqPay), Checkbox and Nova Poshta cash registers, do not require monthly currency commissions and have low total cost of ownership. If an active entry into the US or European markets is planned — Shopify will be the best choice.
The slowness of WordPress is usually caused by using ready-made multi-purpose themes and heavy builders such as Elementor, which generate thousands of unnecessary code lines and dozens of heavy scripts. We create individual lightweight themes on pure PHP 8.3 with modular Tailwind CSS, minimize the number of plugins and configure Redis caching, thanks to which sites load less than 1 second and show PageSpeed 90+.
Yes. We apply comprehensive engineering hardening: hide CMS version, close access to administrative files, change standard login addresses, configure two-factor authentication, install smart anti-spam filters (Honeypot without annoying CAPTCHAs) and connect Cloudflare WAF to block malicious bots.
Absolutely. We configure the control panel using Advanced Custom Fields (ACF Pro) so that each block has its own clear field: title, photo, description, price. The content manager does not need to understand layout or code — everything is edited in a few clicks, and the website design remains flawless.
Yes, this is an obligatory part of our e-commerce development. When placing an order, the client's data is instantly sent to your CRM (KeyCRM or SalesDrive), a declaration number for Nova Poshta is generated, and through Checkbox or Vchasno. Kasaa automatically registers a fiscal receipt in the tax authorities.
100% rights to the site, source code, database, domain and hosting belong exclusively to you. We transfer all rights and administrative access according to the official acceptance-transfer act.
