I'm leading the Makro Coupon Engine at CP Axtra, replacing Magento's legacy coupon engine with a scalable internal platform. I own its architecture, REST APIs, migration pipelines, and production readiness for high-volume coupon processing.

Before this, I built Android TV's Partner Approval & Management System at Google, replacing a spreadsheet-based workflow with an auditable portal that reduced manual tracking errors by 80%+ and approval turnaround from one month to 3–4 working days. At Goldman Sachs, I delivered inventory-management capabilities for global trading and operations teams while improving inventory flows and reducing transaction and funding costs.

At Accenture Japan, I led teams building e-commerce microservices supporting 5K+ daily transactions and 99.9% uptime, as well as an integration platform adopted by 10+ clients that reduced manual effort by 70%. I also built RAG-based AI solutions and a customer-support chatbot that increased productivity and reduced call-center dependency.

I enjoy owning systems end to end—from architecture and implementation through production deployment—using Java, Spring Boot, AWS, Kafka, PostgreSQL, and event-driven design. I bring hands-on engineering leadership, strong system design, and a focus on measurable operational outcomes.
