  • Akolads
    Web Developer
    DIGITAL AND IT
    January 2025 - Today (1 year and 7 months)
    Lyon, France
    Context
    Akolads is my web agency. I leverage over 10 years of experience in web development and entrepreneurship to support my clients on their custom projects, from showcase websites to complex business applications, including artificial intelligence integration.

    Custom Application Development in Ruby on Rails
    I design and develop custom web applications for business needs that standard tools do not cover:
    • Back-end architecture and data modeling in Ruby on Rails
    • Full-stack development, from API to user interface
    • Integration of third-party services and API design (REST, GraphQL)
    • Tested, maintainable code designed to evolve over time

    AI Agents & Automation
    I integrate artificial intelligence into the heart of my clients' tools:
    • Development of AI agents and assistants connected to LLMs (OpenAI, Anthropic)
    • Implementation of RAG systems for querying knowledge bases
    • Automation of time-consuming business processes
    • Connection of AI to clients' existing applications and data

    Websites & E-commerce

    Custom showcase websites in code (HTML / CSS / JavaScript), without templates
    Shopify e-commerce stores (Shopify Partner)
    Websites designed for performance and conversion

    SEO & GEO

    Natural referencing strategy (SEO): audit, keywords, on-page, link building
    Optimization for generative search (GEO) to be cited by AI and new search engines
    Content production and performance monitoring

    My Approach
    Beyond the technical aspects, I bring a product and business vision from my own entrepreneurial projects (Le Baroudeur du Vin, Kareho). I understand my clients' challenges beyond the code and I commit to concrete results: an application that saves time, a website that converts, referencing that generates qualified traffic.

  • Le Baroudeur du Vin
    E-commerce & SEO & Marketplace Developer
    E-COMMERCE
    January 2020 - December 2025 (5 years and 11 months)
    Lyon, France
    Project Context
    Le Baroudeur du Vin is an e-commerce project that I founded and developed from scratch, with the ambition of introducing wines from elsewhere to the greatest number.
    I handled all the technical aspects: store design, custom development, content, and natural referencing.

    E-commerce Development on Shopify
    I designed and developed the entire online store on Shopify:
    • Catalog of over 1,500 items
    • Recurring monthly subscriptions to retain customers and generate predictable revenue
    • Editorial blog integrated into the site
    • Advanced theme customization (HTML, CSS, JavaScript, Liquid) and conversion funnel optimization

    Custom Marketplace Development in Ruby on Rails
    I developed the marketplace part of the platform from scratch in Ruby on Rails:

    • Connection with about ten partner resellers
    • Management of orders, inventory, and sales distribution
    • Design of the back-end architecture, data model, and administration interface
    This part illustrates my ability to combine a turnkey solution (Shopify) with custom application development when the business need exceeds standard tools.

    SEO Strategy and Results
    I managed all natural referencing:
    • Keyword research, on-page optimization, link building, and editorial production
    • Ranking on the first page of Google for competitive keywords
    • Over 1,000 organic visits per day, qualified traffic that directly fueled sales and subscriptions
    Skills Used
    Ruby on Rails development, Shopify e-commerce, front-end integration (HTML / CSS / JavaScript), SEO strategy, and product management.
    It is this versatility — developing a custom application while mastering business challenges — that I now offer to my clients through my agency Akolads.

    • Efficient and structured data exposure for front-end needs
    • Performance optimization (N+1 problem management, efficient resolvers)
    • Close collaboration with front-end developers consuming the API
    Technical Challenges
    Working on a production platform involved balancing new feature delivery with code quality:
