At Gerniks, I lead backend and platform engineering for CC Hub, an internal admin platform covering the debt-collection lifecycle. I own technical planning, architecture, code review, and delivery coordination while staying hands-on with backend development.
For CashControl Consulting GmbH, I designed and shipped a production PSD2 / Open Banking integration service in Node.js / Express.js, connecting banking transaction data to payment reconciliation and finance operations. I also built the Debtor Portal end-to-end with NestJS, Vue 3, and PostgreSQL.
I built and scaled the customer-facing Kundenportal for creditor clients, supporting around 2,000 active users. The wider platform connects portals, internal admin tools, queue-driven workers, scheduled processes, and third-party APIs.
At Mapp Digital, I contributed to a high-volume Node.js email delivery platform and built Django-based internal tools. I also shipped a Shopify integration that captured catalog, cart, and behavioral events into Mapp Cloud for customer mapping, segmentation, and marketing automation.
