# PrestaShop

> PrestaShop has been one of my two specialities since I started out in 2019. I work directly on the core code, modules and theme, on recent installs as well as older versions still in production.

## Flexible, but demanding to maintain

PrestaShop allows a great deal of customisation, which is also what makes it hard to maintain over time: every module added, every core file override, every theme customisation is a potential friction point at update time. A good part of my work on this platform is untangling the layers of customisation accumulated over the years to work out what can be updated without breaking everything.

I work on shops with a small catalogue as well as installations with tens of thousands of references, where performance and indexing become central concerns.

## What I do on PrestaShop

- **Troubleshooting and module fixes** — Diagnosing an error, a module conflict or a regression after an update. ([/prestashop/erreur-500](/prestashop/erreur-500))
- **Version migration** — Upgrading within the same branch, or migrating from a 1.6 install to a currently maintained version. ([/prestashop/migration](/prestashop/migration))
- **Custom modules and overrides** — Building a dedicated module when nothing on the market matches the exact need. ([/prestashop/module-sur-mesure](/prestashop/module-sur-mesure))
- **Performance on large catalogues** — Optimising queries and indexing for shops with a large product volume. ([/prestashop/boutique-lente](/prestashop/boutique-lente))
- **External integrations** — Connecting to an ERP, a carrier or a marketplace, from the core or a dedicated module. ([/prestashop/problemes/connecter-erp-fournisseur-api](/prestashop/problemes/connecter-erp-fournisseur-api))
- **Audit before taking over** — Assessing the real state of an existing install before committing to work or further development. ([/creation/reprendre-un-site-existant](/creation/reprendre-un-site-existant))
- **ChatGPT Ads module for PrestaShop** — Deduplicated OpenAI pixel and Conversions API, oppref kept until the order, consent respected: built and installed by me. ([/prestashop/module-chatgpt-ads](/prestashop/module-chatgpt-ads))

## On versions

> I work on the versions currently maintained by the publisher, as well as older 1.6 installs for troubleshooting or migration. I always flag if a given version limits what's reasonably feasible.

## FAQ

### Do you still work on PrestaShop 1.6?

Yes, for troubleshooting or migrating to a newer version. I flag the limits specific to a version no longer actively maintained by the publisher.

### Do you build custom PrestaShop modules?

Yes, when no existing module fits the need, or when a specific feature needs to integrate cleanly with the platform's core.

### Does a large catalogue cause particular problems?

It shifts the priorities: database queries, indexing and caching become more sensitive, and a performance audit often becomes worthwhile before any new development.

### Will you take over a PrestaShop project built by someone else?

Yes, provided I can access the code and assess its state. I say clearly if customisations make clean work difficult without a larger rebuild.

### Is PrestaShop still a good choice today?

It depends on the project: how much customisation you need, your product volume, and the skills available to maintain it long-term. I can discuss this honestly rather than recommend the platform by default.

### How many modules have you already built for PrestaShop?

I don't put a number on this site, because it wouldn't say much about the real complexity of each module. What matters more is discussing your specific need and seeing whether it matches what I know how to build properly.
