About

Structured thinking with operational discipline

I have a background in accounting and compliance-oriented environments, combined with hands-on experience in quantitative trading systems, backend development, and workflow-driven system design.

My experience spans tax administration, SAP-related system support, information systems development, and algorithmic trading infrastructure. I focus on building systems that integrate structure, execution, and reliability under real-world constraints.
