Translate prototypes into maintainable Liquid sections, merchant controls, app boundaries, and responsive behavior.
Senior Commerce Systems Engineer
I design and de-risk complex commerce systems.
From Shopify Liquid themes and subscription migrations to Adobe Commerce checkout, inventory, payments, and production incidents, I turn prototypes, legacy code, and operational failures into maintainable, evidence-backed releases.

Selected work
Storefront craft, systems depth, operational judgment.
Three case studies show the range: visual Shopify delivery, transactional reliability, and multi-brand Adobe Commerce scale.
A static design direction needed to become an editable Liquid homepage without coupling brand features to customized vendor-theme code.
A time-bound purchase flow crossed OTP access, private product discovery, checkout, payments, dealer inventory, and fulfilment.
A single Adobe Commerce instance powers regional brand sites, product catalogs, sample requests, store lookup, and design-service journeys.
Profile and approach
Senior engineering across storefronts, platforms, and operations.
I fit best where the work needs more than ticket-taking: translating designs into editable storefronts, untangling platform and integration boundaries, diagnosing production behavior, and carrying risky changes through evidence, QA, and a clear release handoff.

Trace checkout, payments, inventory, queues, APIs, configuration, and data before changing production code.
Keep scope, evidence, approval, rollback, and handoff explicit so teams can operate the result safely.
Proof employers can scan
Evidence at the point of decision.
The strongest work is not a technology list. It is a traceable path from uncertainty to a verified decision, with shipped work separated from investigation and gated follow-up.
| Work | Decision | Verification | Status |
|---|---|---|---|
| Shopify / LiquidEditable storefront | Keep brand behavior in merchant-controlled sections and isolated extension files. | Six boundary widths, zero new Theme Check offences, live unpublished preview. | Shipped |
| Magento / ReliabilityFail-closed transactions | Keep OTP, checkout, payment, inventory, and fulfilment boundaries explicit. | Headed browser flows, PII-free queue payloads, database and configuration checks. | Validated |
| Data / OperationsIdentity before interpretation | Prove environment, permissions, time window, and mutation scope before acting. | Read-only access, scoped masking, reproducible reports, durable handoff. | Operational |

Tools that make delivery more durable.
Private and internal systems are secondary to client delivery, but they show how I turn repeated engineering friction into reusable workflows.
A private AI-assisted engineering memory and knowledge graph built across projects and clients.
Phone-first Telegram-to-Codex bridge for approving and routing autonomous engineering tasks from an iPhone.
Reusable SQL and CLI tools for order, inventory, and tracking reporting in Adobe Commerce.
