2026–Present
JANUS et Cie
Full-stack engineering and technical leadership across a headless storefront and custom sales platform, spanning payments, product and pricing models, data architecture, third-party integrations, and client-facing technical decisions.
At a glance
My responsibility
What I owned and contributed.
- Acted as a primary client-facing technical resource for Shopify data modeling, CMS authoring, product configuration, and third-party ownership boundaries.
- Personally implemented payment-confirmation behavior across the custom sales application, including persistent confirmations, reconciliation identifiers, and safeguards around asynchronous payment finalization.
- Diagnosed a cart-pricing issue caused by platform input constraints on unusually complex product data and turned it into a concrete data-contract problem.
- Clarified frontend, database, API, and integration ownership before decomposing cross-repository work into implementation contracts.
- Made release decisions based on customer safety when technically complete work still depended on upstream catalog or integration state.
A hard problem
Tracing a pricing failure across product data and Shopify Functions
A customer-visible pricing discrepancy only appeared after a product reached cart. The investigation connected correct storefront behavior, complex product configuration, and a Shopify Function input constraint. The important part was separating where the system was behaving correctly from where data was being truncated, then turning an opaque pricing bug into a concrete contract that could be fixed.
What this project demonstrates
What changed, shipped, or mattered.
JANUS is strongest as evidence of technical authority, full-stack implementation, production judgment, and client trust rather than a single business metric. The work spans commerce, payments, data modeling, CMS authoring, integrations, and custom sales workflows.
