Catalog, combinations, modules, themes, multi-store, SEO, security, performance.
Before starting, we run a 1-minute tech check — microphone, ambient noise, connection. If your setup isn't good enough, the test is fully refunded.
Show in 15 minutes that you truly know PrestaShop — catalog architecture, custom modules, performance tuning and multi-store — not just a buzzword on your LinkedIn profile.
The Plume PrestaShop badge is a 15-minute AI-conducted oral exam that probes your hands-on command of the platform. The examiner covers catalog architecture (combinations, attributes, features), custom module development using hooks and overrides, multi-store configuration, on-site SEO, performance optimization (CCC cache, Redis, CDN, slow SQL queries), and ecosystem integrations with ERPs, PIMs and marketplace connectors. You take the exam in your browser with no installation required, and you get your score plus a detailed breakdown report right after.
Unlike multiple-choice certifications, Plume's oral format is dynamic: the AI follows up, digs into vague answers and adjusts its questions to the version of PrestaShop you actually work with. The exam questions were calibrated by experienced PrestaShop practitioners — agency developers, freelance architects, e-commerce tech leads — specifically to tell apart someone who has really shipped production stores from someone who only knows the vocabulary. After the session, Claude Opus reads the full transcript and produces a 0-to-100 score with a level (Novice / Proficient / Advanced / Expert) and a detailed written justification per dimension.
This badge is built for freelance developers who need to win client trust without a lengthy demo, for agency teams looking to benchmark their skills objectively, for job seekers who want a credible signal in a stack of résumés where every candidate claims to know PrestaShop, and for store owners who manage their own shop and want to understand where they really stand before hiring a developer or outsourcing a migration.
Here are the concrete dimensions the AI examines during the 15-minute oral.
Designing scalable category trees, handling virtual and downloadable products, structuring combinations, attributes and features without creating technical debt in the ps_product_attribute tables at scale.
Building native PrestaShop modules following platform conventions: hook registration, Smarty vs. Twig depending on the PS version, MVC structure, proper use of ObjectModel and cross-version compatibility practices.
Knowing when to use a hook (non-destructive, adjustable priority) versus a class or controller override, and understanding the long-term maintenance and upgrade-risk trade-offs of each approach.
Configuring the multishop context: sharing or isolating catalogs across shop groups, managing store-specific pricing rules, theme overrides per shop and tax configurations without breaking global coherence.
Diagnosing and fixing bottlenecks: CCC cache activation, slow query analysis in the back office, memcached/Redis configuration, php-fpm tuning and CDN setup for static assets on high-traffic stores.
Connecting PrestaShop to the broader stack via native REST webservices, connector modules (ERP, PIM, Channable, Lengow) or custom XML/CSV flows, with solid handling of sync conflicts and error recovery.
Configuring friendly URLs, product and category meta tags, automatic sitemaps, 301 redirect strategies for migrations and integration of analytics tools (GA4, GTM) through modules or native hooks.
Objectively evaluating when PrestaShop is the right choice versus Shopify, WooCommerce or Sylius, and articulating the concrete impact of the Symfony migration in the PS 8 and PS 9 core on daily development work.
Final scoring is performed by Claude (Anthropic), which reads back the full transcript and applies this weighted criteria grid.
Real understanding of PrestaShop internals: hook lifecycle, override mechanics, database schema, cache layers and the request cycle from front to back. The evaluator distinguishes surface-level answers from genuine under-the-hood knowledge.
Quality and specificity of the examples you bring: catalog volume, combination complexity, multi-store scenarios, integrations built. Precise anecdotes — PS version, modules used, bugs fixed — carry far more weight than generic claims.
Capacity to diagnose critical situations — slow storefront, module conflicts, failed migration — and describe a structured, pragmatic approach to resolving them in a live production environment.
How well you structure answers, your correct use of PrestaShop-specific terminology (displayProductButtons vs. actionProductUpdate, attribute vs. feature) and your ability to explain technical decisions without losing precision.
Your perspective on PrestaShop's evolution (PS 8, PS 9, Symfony in the core, new back-office), knowledge of realistic alternatives and ability to advise a client on platform choice or migration strategy.
A Plume session takes about 20 minutes, from tech check to badge delivery.
You join the exam room directly in your browser. Your mic is tested and audio permissions confirmed. Nothing to install — the oral starts as soon as you're ready.
The AI asks you to introduce yourself and describe your most recent or most representative PrestaShop project — PS version, catalog size, your exact role. This is your chance to set the context for the rest of the conversation.
The AI works through 4 to 6 targeted questions across the key dimensions: catalog and combinations, module development (hooks vs. overrides), performance, multi-store, ecosystem integrations and technology fit. It follows up on incomplete answers and digs deeper when it senses there's more to unpack.
The AI invites you to step back: what's your take on PrestaShop's direction with the growing Symfony footprint in PS 8 and PS 9? What's the real impact on how you build and advise on projects today?
Claude Opus analyzes the full transcript, assigns a score from 0 to 100 with your level (Novice, Proficient, Advanced, Expert) and generates a detailed written report justifying each dimension. Your shareable badge URL is ready right away.
Your score out of 100 translates into a level a recruiter can grasp at a glance.
You've installed PrestaShop and configured the basics: creating simple products, managing orders, installing modules from the marketplace. You haven't yet built a custom module or managed a complex catalog with multiple attribute combinations.
You work regularly with PrestaShop in production: you manage catalogs with combinations, customize themes, install and configure third-party modules. You know how to read logs, enable debug mode and resolve common module conflicts.
You build native modules, use hooks and overrides confidently, manage multi-store setups and optimize performance through cache, SQL tuning and CDN. You integrate PrestaShop with ERPs or marketplaces and are comfortable with the REST webservices API.
You architect high-volume PrestaShop projects (hundreds of thousands of SKUs, millions of monthly visits), contribute to or maintain published modules, lead major version migrations (PS 1.7 to PS 8/9) and advise clients on platform choice with precise technical and business criteria.
No degree or years of experience required to take the badge. Here are the profiles it makes the most sense for.
Prove to prospects that you go beyond module installation: a scored badge is far more convincing than a project list on a portfolio that nobody can independently verify.
Stand out within your team or when switching jobs. The detailed report also pinpoints your skill gaps so you can level up on exactly the right areas.
Validate that you know PrestaShop well enough to hold your own with a developer, spot overcharging and make smarter technical calls on your store without being fully dependent on an agency.
Stand out in a stack of CVs: an objective score lets a recruiter calibrate your level instantly, without running a long and expensive technical test of their own.
Build credibility with dev teams and clients by proving you genuinely understand PrestaShop's constraints, not just its feature checklist.
Where and how your PrestaShop badge will help you day to day.
A client is looking for a PrestaShop developer to rebuild a catalog with 50,000 combinations. You drop your Advanced badge URL into the proposal. The client instantly understands your level without scheduling a separate technical interview.
An e-commerce agency receives 30 applications for a senior PrestaShop developer role. Candidates with a Plume badge let the hiring team filter objectively before the technical round, cutting time-to-hire significantly.
A proficient developer scores 63/100 and receives a report flagging weak coverage of REST webservices and multi-store pricing. They target those exact areas in their learning and retake the badge six months later with a higher score.
A store owner who has run their PrestaShop shop for three years takes the badge before hiring a developer. The report confirms they have solid BO and catalog skills but should delegate anything touching custom modules and server-side optimization.
A PS 1.7 developer planning to move to PrestaShop 9 takes the badge to surface blind spots around the new Symfony-driven core. The report gives them a concrete roadmap for the transition.
A freelance e-commerce consultant adds their Expert PrestaShop badge link to their LinkedIn profile. Recruiters and clients who click see the score, the written summary and the audio excerpt — a far stronger proof point than a self-declared skill tag.
A few minutes to check you have everything you need.
At the end of your session you don't just get a score — here's everything that awaits you.
