How can I help?
PHP upgrades
I upgrade PHP, Symfony, Laravel and WordPress systems, as well as custom applications built without a framework. I update ageing code, libraries and integrations affected by version changes.
I check code compatibility, adapt it to breaking changes and test key parts of the system: forms, payments and background tasks.

PHP version upgrade required
Your PHP version is no longer supported. An upgrade is recommended.
Bug fixes and performance optimisation
I diagnose recurring errors, slow pages and problems that are difficult to reproduce. I analyse the source code, integrations and server configuration to identify the cause.
I optimise old PHP code, reduce unnecessary calls and queries, and check for similar issues elsewhere in the system.

User interfaces and server-side rendering
I improve the parts users interact with directly: forms, navigation, tables, filters and dashboards. I work with Vue, React, server-rendered pages and interfaces integrated into existing PHP systems.
This includes fixing broken functionality, making layouts responsive on mobile devices and building new application screens with a consistent style.

+Forms and filters
+Mobile layouts
+Server-rendered pages (Blade / Twig)
API integrations and background processes
I build and maintain API integrations, payment gateways and automated processes: emails, data imports and exports. I work with job queues, background workers and scheduled tasks.
When tasks stall or fail, I identify the causes in the application code and processes, checking retries, time limits and configuration.

New modules and features
I extend running systems with the functionality a business needs: reports, internal tools, new workflows and connections to external services. I work with Symfony, Laravel and custom PHP systems.
Changes cover both the user interface and the backend. I ensure new functionality fits smoothly into the existing system without disrupting its operation.
Symfony, Laravel, custom PHP architecture
+Automatic invoice generation
+Data exports to accounting systems
+Filtering and sorting enquiries by topic
Server and environment configuration
I configure the environment needed for reliable operation: PHP settings, web servers, background processes and scheduled tasks. I resolve issues where the same code behaves differently across environments.
I align system requirements with server settings, make the necessary changes and provide a clear configuration summary.
PHP settings (php.ini), Nginx / Apache, background services
+PHP settings configuration
+Background processes and monitoring
+Scheduled tasks (cron)
How we work together
-
1. Assessment and audit
You tell me about the system and its current challenges. I review its behaviour, code, integrations and server environment to establish a clear starting point.
-
2. Planning and priorities
We agree on priorities and stages of work. I assess dependencies, potential risks and the time needed so the scope is clear before we begin.
-
3. Implementation and testing
I carry out the agreed development work while preserving the existing system structure. I thoroughly test the affected processes and check for unintended errors.
-
4. Launch and support
I document the changes and important settings, and provide recommendations for the future. If the system needs ongoing maintenance, we agree on a support plan.
