Experience

I take broader technical ownership of product systems while staying directly involved in how their backends, integrations, deployments, and production behaviour work.

• Define and review system behaviour, backend and API boundaries, and implementation work.
• Guide integrations and deployment work while keeping production concerns part of delivery.
• Investigate production failures, correct implementation problems, and remain technically accountable for the result.

I worked on SAP and connected business applications, building a practical understanding of business rules, transactional workflows, and integration boundaries.

• Built ABAP reports and dialog or module-pool applications using DDIC, function modules, and BAPIs.
• Worked with MM-, SD-, and FI-related workflows and the application rules around them.
• Developed business applications and application-side SAP integrations.

I started in payment operations, where software-driven processes met physical machinery and real transaction flows.

• Generated and packaged secure PIN material.
• Operated and maintained the related machinery.
• Tested ATM and POS transaction flows.
