# PrestaShop stores and modules, from legacy to current.

I build custom modules and themes, fix performance and security problems, and help stores that have fallen behind move to a supported PrestaShop and PHP version.

## What I do

### Custom modules

Modules built to PrestaShop conventions, with hooks and overrides kept to a minimum.

### Themes

Theme changes and child themes that survive updates.

### Upgrades and migrations

Planned moves to PrestaShop 9 on maintained PHP, with data, modules and SEO checked.

### Performance

Slow product and category pages traced to their cause and fixed.

### Security

Module audits against known advisories, and fixes for vulnerable code.

### Multistore and languages

Multistore setups, translations and international catalogues.

## Older stores are a growing risk

PrestaShop 1.6 and 1.7 no longer receive official security fixes, and neither do the PHP versions they run on. An upgrade costs less than a breach. I can assess your store and plan the move.

**Maintaining many stores?** nuvols.app, my own product, gives agencies one dashboard for every PrestaShop store they look after.
