Behind every line of code, there's an intention: yours.

My job is to understand it, protect it, and build what follows — built to last.

Laurent Decottegnie — développeur fullstack à Québec
QC · CA · 46.81°N

My name is Laurent Decottegnie. I'm a full-stack web developer based in Quebec, and I support clients across Canada, Europe, and worldwide with modern architectures, headless implementations, and custom-built digital solutions.

My journey has brought me through large companies, ambitious startups, and fast-growing scale-ups. Over time, I realized that I am most fulfilled working on human-scale projects - where trust can be built more easily and more directly.

I build tailored solutions adapted to your reality and your needs. Data analysis, automations, custom assistants, or tools powered by artificial intelligence-everything is designed to genuinely improve your daily workflow and support the growth of your business.

Clarity, method, and reliability are at the core of how I work.

[ 03 · Career ]

17 years modernizing web platforms.

Over the years, I've delivered measurable value to a wide range of web platforms: full redesigns, code optimization, creation of secure APIs, and development of custom tools.

My approach combines rigor, modernization, and strong architectural thinking to support system growth and reliability.

[ 01 · Modernisation ]

Rebuild & technology migration

Major platform overhauls (Jobboom, Boomrank) shipped with zero downtime. Progressive migrations, technical debt cleared, teams up to speed by the end so your application becomes a growth asset again, not a brake.

[ 02 · Backend ]

Robust backend solutions

A backend that talks to the frontend via API3, two distinct disciplines, kept aligned. This clean separation of concerns makes evolution smooth: change the interface without touching the logic, evolve the business layer without recompiling the front. This very site runs on that principle - Svelte on the visitor side, Laravel on the application logic side.

[ 03 · Frontend ]

Frontend interfaces built to last

Svelte, Vue, React or even Angular? The choices are endless for your project. A proper analysis of technical needs is essential to make informed decisions rather than follow the trend of the moment. Code that stays understandable and maintainable over time.

[ 04 · DevOps & Qualité ]

Deployment & active monitoring

Ship easily, structure cleanly, and above all monitor actively. Docker and CI/CD (GitLab or GitHub Actions), automated tests, real-time monitoring of errors and performance, regular and tested backups. Nothing is left to chance: a proactive alert system keeps me informed when issues arise, so I can intervene before your visitors are affected.

[ 04 · Shopify Headless ]

Shopify headless: your store, fully customized, without limits!

Shopify is an excellent solution to help you sell online, but its limits appear as soon as you want to go further: advanced customization, automation, business logic, or marketing analytics.

With a headless architecture, I combine the power of Shopify's APIs with a fully custom application layer.

Your store becomes faster, more flexible, and infinitely scalable.

    [ Performance & visibility ]

    Ultimate performance

    Your store loads instantly, even on mobile.

    A fast website reassures visitors, improves SEO, and reduces cart abandonment.

    More conversions, fewer losses.

  2. 02
    [ Automation ]

    Application intelligence

    Your store becomes more than a simple catalog: it automates tasks, adapts, executes marketing rules, and manages advanced scenarios.

    Your store becomes a true intelligent system.

  3. 03
    [ Design & freedom ]

    Total flexibility

    Custom design, integrations, AI features, unique functionalities...

    You're no longer limited by Shopify: everything becomes possible.

  4. 04
    [ Shopify reliability ]

    Unchanged administration

    You keep everything you love about Shopify's native dashboard, while benefiting from a custom application layer.

    You get the best of both worlds.

[ 05 · Joomla! · Since 2008 ]

17 years of expertise with the Joomla! CMS

As Joomla! specialist since 2008, I support professionals across North America and Europe in designing custom extensions (components, plugins, templates), modernizing existing websites, and optimizing performance.

  1. [ 01 · 6 ] 01

    Tailored extensions.

    Components, plugins, templates: adaptation of existing extensions or from-scratch development to fit your business logic. To close the exact gap between what Joomla! does out of the box and what your operation actually needs.

  2. [ 02 · 6 ] 02

    Migrate without losing anything.

    Joomla! 1.5 → 3 → 4 → 5 migrations with zero data loss and no downtime visible to your visitors. Rollback ready, content verified - your site comes out intact and up to date.

  3. [ 03 · 6 ] 03

    Performance you can see.

    Lean architecture, optimized queries, properly tuned caching. A faster site means better SEO and fewer abandonment on mobile.

  4. [ 04 · 6 ] 04

    Code that holds over time.

    PHP 8+ development aligned with current Joomla! standards. Code written to best practices, designed to follow CMS upgrades without surprises. Your site stays maintainable for 5 years.

  5. [ 05 · 6 ] 05

    Templates that look like you.

    Custom design cleanly integrated into Joomla!. You keep full content control; your visual identity doesn't suffer from a generic store-bought theme.

  6. [ 06 · 6 ] 06

    Autonomy passed on.

    Technical coaching and clear documentation so your team can maintain the site without depending on me for every small change. The goal: you need me less and less.

[ 08 · Let's talk ]
