About Kinane

Software Engineer in SaaS and E-commerce as a CTO as a service, freelance, or founder.

From the technical management of a major contest for a content creator (La Boiserie) to the release of public Shopify applications (Retailed Size Chart, TurboBundle), I have also recently worked for HighCohesion, Autrement Studio, Origine.care, Respire, and Retailed.io.

Obsessed with reducing technical debt and all sorts of feedback loops, I work a lot with these paradigms: TDD, Actor Model / Event-driven Architecture, Finite-State Machine, Functional Programming, Durable Execution / Workflow Orchestrations.

  • retailed.io
    Co-founder / Apps Maker
    November 2023 - Today (2 years and 7 months)
    I worked with Retailed to launch the first size chart app that uses Shopify's best practices.

    1️⃣ Size charts are always synchronized with catalogs.
    2️⃣ No impact on store speed as everything is hosted and relies on Shopify via their hosting and persistence via metafield/metaobjects.
    3️⃣ Ability to match a size chart to multiple products via a product matcher.
    4️⃣ Builder system with the ability to add custom images/videos/tables, everything is added natively to the store without style defects.

    Available on the app store: https://apps.shopify.com/retailed-size-chart-guide?locale=fr

  • la-boiserie.fr
    CTO as a Service
    E-COMMERCE
    March 2022 - October 2022 (7 months)
    France
    The objective was to migrate the E-commerce activities of the content creator La Boiserie to a pragmatic, easy-to-manage, and scalable technical stack for future projects.

    - Management of the "M3G80 CONTEST" contest (€160K cash prize), landing page, third-party management, and technical smooth running of the event.
    - Migration, Theme, and custom plugins for essencial-airsoft.fr.
    - Migration from saleor (not scalable enough during events like contests) to Shopify for the main store (la-boiserie.fr), custom theme and app for bundles and invoice management.

We collaborated with Kinane on the development of our Shopify application, and his advice proved extremely valuable, both for technology choices and for the processes to follow when deploying to the Shopify App Store. I highly recommend his technical expertise and his great responsiveness.
