About Julian Kocmut

# Senior web developer for demanding WordPress systems

Since 2017 I have been developing and maintaining production websites, online shops and custom client systems. My focus is WordPress and PHP – from custom themes and plugins through WooCommerce and integrations to migration, security and complex troubleshooting.

At a glance

### Experience

Commercial web development since 2017

### Location

Graz, Styria, Austria

### Core stack

WordPress · PHP · WooCommerce

## Development, operation and problem-solving from one source

I don’t just accompany web projects up to launch. A large part of my work happens where systems have to run reliably day to day, be extended, migrated or technically modernised after years.

### Custom WordPress development

Custom themes and plugins, Gutenberg and ACF, Elementor extensions and project-specific features instead of unnecessary off-the-shelf solutions.

### WooCommerce & integrations

Online shops, booking systems, external APIs and multilingual content for production client projects.

### Improving existing systems

Relaunches, migrations, legacy modernisation, performance work and complex troubleshooting in live operation.

### Security & recovery

Security hardening, malware clean-up and the controlled stabilisation of compromised or older installations.
