EVENT: order.placed — NEW ORDER RECEIVED

I build the backends behind brands you know.

Parth Thummar — Sr. Backend Developer & eCommerce Solutions Architect. Greater Boston, MA.

STAGE 02 — order.validated

Checks passed.

Thirteen-plus years of Magento and Adobe Commerce backend engineering: ERP integrations, RabbitMQ message queues, custom GraphQL schemas, Varnish and Redis caching layers, zero-downtime migrations, payment systems, and B2B workflows at enterprise scale.

“Backend lead” in practice means owning the systems that keep money moving when nobody is looking — the inventory sync at 3 a.m., the payment capture during a holiday traffic spike, the migration nobody noticed because nothing went down.

American Musical Supply (AMS)

Sr. Adobe Commerce Developer / Backend Lead — full-time

Backend leadership on Adobe Commerce Cloud for the musical-instrument retailer — a Salesforce Marketing Cloud migration to Listrak, Synchrony financing beside Affirm, rewards at catalog scale, and AI coding guardrails for the dev team.

  • Salesforce → Listrak cutover
  • 20–25 SSIS feeds
  • ~25K reward SKUs
  • Synchrony financing build

Focus
Marketing integrations · financing · rewards · AI guardrails
  • Architected the move from Salesforce Marketing Cloud to Listrak, owning Adobe Commerce APIs for order-confirmation email, SMS notify-me, checkout opt-in, and hourly bearer-token refresh. Ran the production switch that replaced Salesforce form controllers ahead of the contract end.
  • Mentored migration of approximately 20–25 SSIS feeds, including SQL-side JSON grouping previously handled by Salesforce.
  • Drove the Synchrony financing build beside Affirm: one promo per order, a custom cipher-token settlement path outside the vendor extension, and rewards exclusion on financed orders. Worked with Synchrony on sandbox, promo-override, and daily funding-report constraints; public launch was targeted for mid-to-late January.
  • Set repo standards, managed settings to block secret writes and unapproved commands, and prompt-injection hooks for Claude Code and Cursor. Piloted team rollout to keep AI coding tools available while protecting credentials and production configuration.
  • Delivered customer rewards with standardized points, SKU-level ratios, item-level calculations, and checkout integration hardening. Scaled catalog rewards from approximately 5,000 to 25,000 SKUs, using a Fastly purge to keep PDP badges consistent.
  • Led feed migration planning for approximately 22,000 SKUs with hourly updates across Google, Bing, and Meta — aligning flat-file/API ingestion and delta strategies with margin tiers, price thresholds, and out-of-stock filtering.
  • Partnered with marketing on GA4/GTM and OneTrust compliance audits, investigating consent gating gaps and scoping fixes for tag firing, restricted data processing, cross-domain linking, and conversion inflation risks.
  • Owned incident-aware release execution, coordinating monitoring and communications and running time-boxed releases with observability markers and checklists.
  • Stabilized staging by isolating branch-related deployment failures and enforcing release-branch baselines to reduce environment churn and accelerate QA.

Wabash National

Backend Lead — Wabash Parts headless PWA

Led Adobe Commerce delivery for the Wabash Parts storefront — a headless PWA with a custom GraphQL schema, real-time ERP sync through HTI and Boomi, VIN-based parts lookup, and sprint planning and releases in Azure DevOps.

  • HTI / Boomi integration
  • ~50K sellable SKUs recovered
  • VIN-based parts lookup
  • Magento 2.4.9 · PHP 8.4
Role

Focus

  • Led delivery of the Wabash Parts headless PWA and custom GraphQL schema, with sprint planning and releases managed in Azure DevOps.
  • Built HTI integration for products, orders, and inventory: real-time customer pricing and quantity-on-hand through Boomi, outbound order XML, and inbound catalog and inventory files. Recovered approximately 50,000 sellable SKUs dropped by a missing file chunk.
  • Shipped the Magento 2.4.9 upgrade on PHP 8.4, then fixed JWT session expiry, base64 customer IDs for the frontend, and an inventory-index bug that cleared stock on unrelated SKUs.
  • Designed admin-managed company roles and permissions with GraphQL allow/deny rules enforced in the PWA, plus a daily HTI supersession import that copies old-SKU attributes to replacement SKUs without repeat overwrites.
  • Drove VIN-based parts lookup (VINBOM), including assembly views and a visual trailer map. Split product calls from price calls after HTI per-SKU pricing caused page timeouts.
  • Scoped headless Algolia using InstantSearch from the PWA, starting with autocomplete and then product listing. Kept customer pricing and inventory out of the proposed index and dealer part numbers isolated per account.
  • Tightened releases by cutting from the develop branch with feature flags and blocking cherry-picks that reintroduced defects.
