Custom Backend Integrations

Custom Magento / Adobe Commerce Backend Integrations.

Off-the-shelf connectors break when your workflows get complex. I build custom integrations — ERP, CRM, payment gateways, B2B quoting systems — that handle your real business logic, not just the simple cases.

The Problem

Why “plug-and-play” integrations always fall short.

You installed a marketplace connector expecting it to sync your ERP, CRM, or payment gateway. It worked for the simple cases — then your real business logic kicked in and everything broke.

Data Sync Breaks Silently

Orders stop flowing to your ERP, inventory counts drift out of sync, and customer records duplicate across systems. You don’t notice until a client calls asking where their shipment is.

No Custom Logic Support

Your B2B pricing rules, multi-warehouse allocation logic, or custom approval workflows don’t exist in any off-the-shelf connector. You end up with workarounds on top of workarounds — a house of cards.

Vendor Lock-In & Black Boxes

Third-party SaaS connectors control your data pipeline. When they change their API, raise prices, or shut down, your entire order flow stops — and you have zero visibility into what went wrong.

The Approach

How I build integrations that actually survive your real workflows.

I don’t install a plugin and hope it works. I architect custom backend solutions using Magento’s native service contracts, REST/GraphQL APIs, and message queue infrastructure — built to handle your specific business logic.

Workflow Mapping & Scoping

I map your exact data flows: what systems talk to what, which fields need to sync, what triggers each action, and where the current process breaks. This becomes the blueprint for the entire build.

Architecture & API Design

I design the integration architecture using Magento’s service layer — proper API endpoints, queue-based processing for heavy operations, and retry logic for when external systems go down. No brittle direct database writes.

Build & Edge-Case Testing

I build the integration module following Magento coding standards, then stress-test it against your real data — including the edge cases that break marketplace connectors: partial orders, currency mismatches, custom attributes, and concurrent updates.

Staging Deployment & Monitoring

We deploy to staging first, run your actual workflows end-to-end, then go live with logging and alerting in place. You get full visibility into every sync — no more wondering if your data made it across.

Challenge

Sales reps processed quotes manually. Deals were slow to close and the quoting system needed deep HubSpot CRM integration that off-the-shelf solutions couldn’t handle.

Solution

Built a system where quotes created in Magento auto-generate HubSpot deals with stage tracking. Added custom post-order editing so reps could issue partial refunds and charge additional amounts after completion.

Result

Sales reps closed deals faster without hiring additional headcount. The quoting-to-deal pipeline became a core operational advantage for the business.
