Back to original languageAbout David
Certified Expert PrestaShop ★★ (2 stars) — founder of XMEDIACREATION (2004), I now work solo. I intervene mostly when quick and effective troubleshooting is needed: subcontracting for agencies stuck on a technical point, or directly for merchants who want a stable, fast, and profitable store.
What I do (PrestaShop 1.6 → 8.x)
- Custom development : modules, hooks, clean overrides, ERP/CRM/WMS integrations, payments, carriers.
- Debugging & "rescue" : critical errors, cart/order issues, taxes, specific pricing, module conflicts, regressions.
- Migrations / Redesigns : 1.6 → 1.7/8.x, PHP 8.x compatibility, theme refactoring.
- Performance & Technical SEO : TTFB, caching, MySQL optimization, Core Web Vitals, URL structure, faceted search, internal linking.
- Multistore & international : languages, currencies, complex catalogs.
- Security & compliance : anti-bot/spam hardening, updates, GDPR.
Also (as needed)
- WordPress : debugging and custom plugins (imports, APIs, custom back-office), migrations and technical cleanup.
- Showcase websites : careful and performant creation (Bootstrap, good SEO practices). I appreciate MODX for its simplicity and security, but I adapt to your stack.
- Web applications : creation, takeover, or debugging of applications in PHP / MySQL / Javascript.
- HTML5/CSS Integration : integration of your custom web designs.
Method
Quick audit → short action plan → incremental deliverables. Tool-assisted work (Git, staging, logs, SQL profiling), clean and maintainable code.
Why me?
20+ years of experience, certified PrestaShop specialist, used to contexts where quick understanding of existing code, fixing without breaking, and delivering visible gains (stability, speed, conversion) are crucial.
Available for : agency support, express audits and fixes, store evolution, or showcase site creation.
