END CLIENTS ANONYMIZED UNDER AGREEMENT.
Custom decoupled Drupal + MongoDB product-information platform: pluggable import engine (~15 sources), feed engine + OpenAPI hub, DAM, and a CE-marking compliance portal. PIM vendor swapped mid-flight with zero downstream disruption.
Seven bespoke Go services on Confluent Cloud, most in production: PIM→registry publishing, HMAC-signed lead pipelines, and a Snowflake→Kafka→Salesforce pipeline (8 SObjects) taken live for a Baltics launch.
Greenfield headless Drupal 10 + Next.js 14 brand platform: image pipeline on client-provisioned AWS, on-demand revalidation, technical SEO, OpenTelemetry observability, OpenAI translation QA. Editors fill locales editorially — ES/IT/DA shipped, and since active development ended the platform has grown past 20 languages.
Decoupled Drupal + Gatsby corporate platform built by others: led the 9→10 upgrade, same-day polyfill.io remediation, China-market enablement, and legacy Lotus Notes integration kept alive.
On-premise Go + React production-support system shipped as a single statically-linked binary: JWT/RBAC, audit trail, NCR tracking, and a deterministic, fully unit-tested recipe optimizer with PDF/Excel export.
A five-locale corporate platform for a DACH insurance & claims group, run under a decade-long SLA: carried live through three Drupal majors (9→10→11), a custom editor landing-page system, back-end-driven Consent Mode v2, and Solr search — including a core patch contributed upstream.
