About this gig
Need more than a template-based WordPress website?
WordPress works great until your business outgrows standard themes and plugins. A new feature needs custom logic, an integration does not fit cleanly, or a growing catalog starts hurting performance.
That is where Sibers comes in.
We have been building software since 1998, with experience across 50+ WordPress projects - from polished custom frontends to WooCommerce systems, plugins, backend logic, and integrations. That experience includes supporting and modernizing a large international WooCommerce platform connected to the world's largest database of chemicals.
Your project can include:
- Custom WordPress websites and themes
- WooCommerce and payment workflows
- Custom plugins and backend functionality
- API, CRM, and third-party integrations
- Performance, security, and architecture improvements
- Existing WordPress takeover and modernization
The result is a fast, maintainable WordPress system built to evolve with your business.
Message us to discuss your WordPress project and the best next step.

FAQ
Can you build custom WordPress themes or plugins?
Yes. We can develop custom WordPress themes and plugins when standard solutions do not meet your requirements. This can include custom frontend components, backend functionality, business logic, and integrations.
Can you build custom backend functionality in WordPress?
Yes. WordPress can support much more than standard pages and plugins. We can develop custom backend logic, workflows, data handling, admin functionality, and other features around your business requirements.
Can you build or customize a WooCommerce website?
Yes. We work with WooCommerce stores, product catalogs, payments, checkout flows, shipping, subscriptions, and custom e-commerce functionality.
Can you integrate WordPress with external APIs or services?
Yes. We can connect WordPress with payment providers, CRMs, internal business systems, external databases, analytics tools, and other third-party APIs.
What if I already have a WordPress site? Can you customize or improve it?
Of course! We can take over an existing project, fix issues, add new functionality, improve performance or architecture, and continue development from the current codebase.
Can you optimize my WordPress site for speed and SEO?
Yes. We can optimize site performance, caching, database queries, assets, and technical structure. We can also implement SEO-related technical improvements, but search rankings depend on many factors beyond development alone.
Do you provide support and maintenance after launch?
Yes. We can continue with maintenance, updates, new features, integrations, performance improvements, and ongoing development after the initial release.
What do I need to provide to start the project?
Ideally, share your project goals, required functionality, existing website or codebase if applicable, designs or references, integrations, and any technical documentation you already have. If you’re unsure, we’re happy to guide you through the process!
What if I only need a custom WordPress plugin?
We also offer a dedicated WordPress plugin development service for projects focused specifically on custom plugins, plugin customization, or extending existing WordPress functionality: https://www.fiverr.com/ixobit/develop-a-custom-wordpress-plugin-with-api-and-woocommerce-integration
Will communication be in fluent English?
Yes. Our team communicates fluently in English and has extensive experience working directly with international clients across different time zones.
