Web development & maintenance
Reliable development, structured maintenance and ongoing improvements for business websites and web applications.
What we do:
Web development on solid technologies
We develop and maintain websites and platforms using proven and widely adopted technologies.
Projects are built to be stable, extensible and easy to maintain over time.
Bug fixing and issue resolution
We diagnose and resolve technical issues affecting functionality, performance or stability.
This includes conflicts between plugins, broken layouts, errors after updates and unexpected behavior.
Custom development with PHP and JavaScript
We work on custom features, integrations and logic using PHP and JavaScript.
This includes backend logic, front-end behavior and interaction with APIs or external systems.
Updates and security management
We handle regular updates for core systems, themes and plugins.
Security measures are applied to reduce risks and keep the platform protected against vulnerabilities.
Theme and layout customization
We customize themes and layouts to match design and usability requirements.
On WordPress projects, we work with block-based systems and page builders such as Kadence Blocks and Elementor, selecting the most appropriate approach based on project structure, performance goals and long-term maintainability.
Maintenance and continuous assistance
We provide ongoing technical support through our structured ticket-based workflow.
Maintenance activities, improvements and preventive checks help keep your website reliable as it evolves.
Why web maintenance matters
Web platforms require constant attention to remain secure, stable and compatible with modern standards. Regular maintenance reduces downtime, prevents issues and supports long-term sustainability.
A maintained website is easier to evolve and safer to operate.
