Professional journey

My expertise goes beyond any single technology or sector. I have applied my skills across industries as diverse as luxury (Christian Louboutin, Diptyque), sports & lifestyle (Venum, BazookaGoal), retail (Secret Sales, Jardiland, Bio c' Bon), digital agencies (SQLI, Clever Age), and tech (SoftBank Robotics). Each sector comes with its own demands — flawless shopping experiences for luxury, relentless performance for sports, 24/7 reliability for retail. But beyond sectors, it is cross-cutting challenges that shape my daily work: • Architecture & Migration — Leading complex migrations (Magento 1→2, Cloud, microservices) with zero downtime. • Performance & Core Web Vitals — Optimizing load times, cutting error rates, and acing Lighthouse audits. • SEO & Organic Traffic — Boosting visibility, growing organic traffic and preserving rankings during migrations. • Growth Strategy — Advising CTOs and product teams on architecture and roadmap decisions. • Security & Compliance — Ensuring PCI and GDPR compliance and hardening platforms against threats. • Integration & API — Connecting ecosystems (ERP, OMS, CRM, marketplaces, payments) through robust APIs. Every engagement is a new story, every client a fresh challenge. And it is this diversity that makes my journey so rich.

Gemini agent: Google turns enterprise AI into a coworker

On 8 October 2026, Google Cloud announced Gemini agent: a universal agent for work, available in Workspace, Microsoft 365 and Slack, able to run multi-day assignments, with its own identity, an audit trail and spend caps. What this shift changes for your costs, your governance and your teams — and where to start.

Mage-OS 3: the community Magento distribution passes its security crash test

Exploited from 4 September, fixed by Adobe on the 7th, shipped by Mage-OS as an emergency release on the 8th: the StyleSmuggler zero-day gave the community distribution of Magento Open Source a full-scale crash test. While the 2.4.6 and older lines drop out of support, Mage-OS 3 adds an installer, native RMA and PHP 8.5 on top of the 2.4.9 base. What this changes for an Open Source merchant — and the three possible paths.

Adobe Commerce Cloud Service: the October release opens the back office to integrations

Custom prices on cart items, catalog price rules over REST, isolated admin carts, transactional emails handed to a third-party platform, webhooks that know the buyer’s company: the 7 October 2026 release of Adobe Commerce as a Cloud Service is almost entirely about integration. A review of what opens up for ERP, OMS and B2B teams — and of the Bulk API limit to check before the next mass import.

Adobe Commerce composable storefront: the September suite closes the classic gaps

A pick-your-own free gift in the cart, Google Pay and PayPal, multiple wishlists, a shared B2B company address book: the September 2026 storefront suite, published on 6 October, ticks boxes that classic commerce took for granted. For merchants delaying their move to the composable storefront for lack of parity, the gap list just got shorter again — and a reCAPTCHA flag awaits B2B teams.
