EDI

EDI is how established businesses exchange documents automatically — purchase orders, invoices, and shipment notices — without rekeying. I have built the maps and pipelines that translate between EDI formats and internal systems.

My work spans the formats and transport in real use: EDIFACT and ANSI X12 document sets, and how they flow via SFTP, AS2, and VANs. The art is in mapping — segmentation, validation, and error handling that keep partner exchanges reliable.

Because EDI integrates inward, I connect those messages to order and billing systems so incoming documents become transactional records and outgoing documents are generated from real business events, keeping a single source of truth.

The formats are strict and unforgiving, which is exactly why the mapping layer matters. I translate between the partner's EDI segments and the internal domain model so trading works partner-to-partner while the business keeps one clean representation.

Transport is chosen by the partner's reality. SFTP for the common case, AS2 for the assurance-minded, VANs where a network broker manages multi-partner exchange — I wire the appropriate path rather than forcing one size.

Validation and exception handling are where reliability is won. Malformed or unexpected documents must be caught and surfaced, not silently dropped, so a bad exchange becomes a visible, actionable issue instead of a quiet data loss.

The inward integration is what creates value. An incoming order becomes a transactional record, an outgoing invoice is generated from a real business event — so the ERP and the EDI stream agree, with no second entry.

Outbound messages are derived from source-of-truth systems rather than hand-scripted, which keeps them consistent and auditable. If the business record is right, the EDI document that represents it is right too.

EDI is unglamorous but load-bearing: it is the reliable backbone of supply chain and B2B operations. My value is making that backbone correct, validated, and integrated — so the automation is trustworthy even when the format is tedious.

I map the EDI format to the domain model, not to a scraping job. The translation between partner segments and business objects is explicit and clean, not a pile of parse-and-hope.

Validation is strict and unmuteable. Malformed or unexpected documents are caught and surfaced as visible incidents, so a bad exchange becomes an actionable issue, not quiet data loss.

Transport is chosen for the partner's reality. SFTP for the common case, AS2 for the assurance-minded, VANs where a broker manages multi-partner exchange — the right path, not a forced one.

Incoming documents become transactional records. An order maps into the order system with full traceability, so the ERP and the EDI stream agree without second entry.

Outbound documents are derived from the source of truth. If the business record is right, the EDI document that represents it is right — generated from real events, not hand-scripted.

Idempotency and de-duplication protect against re-delivery. A retried or duplicate exchange must not double-create a record.

Every exchange is traceable end to end. message ID, partner, and mapping outcome are logged so an issue can be replayed and diagnosed.

The mapping layer is versioned and testable. EDI changes are covered against a fixture set, so a partner format change is verified rather than discovered in production.

EDI is the reliable B2B backbone. My value is a correct, validated, integrated pipeline — trustworthy automation even where the format is tedious.
