About Nicolas

Your WordPress site is slow, unstable, or limited by a theme?


I design custom, fast, scalable, and maintainable WordPress solutions where standard solutions (Elementor, Divi…) reach their limits.

WordPress & Full-Stack Expert (10+ years), I work on technical and critical projects: performance, advanced WooCommerce, and API integrations.

My areas of intervention:

  • Performance & Core Web Vitals:advanced optimization for fast and fluid websites
  • Complex WooCommerce:conversion funnel, large catalogs, business logic
  • API & Automation:connection to your tools (CRM, ERP, Google…) via custom plugins
  • Clean Redesign:migration to a reliable architecture without SEO loss

Why work with me?

    Here is a proposal for this second experience, focusing on user impact and the professional aspect of optimization.
    Web Performance Optimization: Yes-We-Canyon

    For the Yes-We-Canyon website, I worked on accelerating response times to improve the booking experience and SEO positioning.

    Based on PageSpeed Insights reports, I cleaned up the site's technical structure to achieve concrete gains:

    Speed: 2.1 second gain in total loading time.
    Google Score: 15-point increase in performance index.
    Fluidity: Optimization of critical resources for near-instant display.

    Business Impact:

    Every second saved directly reduces the abandonment rate when viewing offers. By cleaning up the code (without using heavy page builders), I enable the site to remain performant in the long term, thus offering a fluid customer journey that promotes conversion.

    As an experienced French developer, I bring a Full-Stack approach: I don't just adjust cache settings, I address the problem at its source in the code.

    March 2026 - March 2026
    Toulouse, France
    The intervention on the Ailements website aimed to remove technical barriers that were hindering user retention and SEO.

    Using PageSpeed Insights as a benchmark, I restructured the critical elements of the site to transform a slow platform into a high-performance sales tool:

    Responsiveness: Massive 3.4-second gain in page loading time.
    Performance Score: 25-point increase.
    Core Web Vitals Optimization: Improvement of server response times and visual display.

    Added Value for Conversion:

    An wait of more than 3 seconds causes, on average, a loss of 40% of visitors. By bringing the loading time back below critical thresholds, I directly contributed to securing traffic and increasing conversion chances.

    True to my developer philosophy, this optimization was carried out through custom solutions (PHP/MySQL) and code cleanup, avoiding the accumulation of unnecessary plugins that eventually slow down the site again.

    FASHION AND COSMETICS
    March 2026 - March 2026
    Toulouse, France
    I performed the complete technical optimization of the Brinsdivresse agency's WordPress site with a clear objective: business efficiency.
    Thanks to a PageSpeed Insights audit and targeted intervention on the site's engine, the results are immediate:

    Performance Score: Moved from 52 to 92/100.
    Loading Time: Drastic reduction of 5 seconds.
    Core Web Vitals: Optimization of LCP (Largest Contentful Paint), TTFB, and FCP to ensure smooth navigation.

    Why is this important for your business?
    A faster site means a lower bounce rate and a higher conversion rate. By improving these indicators, I ensure not only a better user experience but also a strong positive signal for Google ranking (SEO).

    I always favor custom solutions and clean code to ensure these performance gains are sustainable, without relying on cumbersome optimization plugins.
