Open to new opportunities
Milos Ivkovic Fintech & technical operations.
Technical operations lead specializing in payment orchestration, high-risk processing and headless e-commerce. I bridge commercial strategy and engineering: writing BRDs for smart routing engines, integrating multi-rail payment gateways, and keeping production infrastructure running as the business grew past break-even.
Experience. Where I’ve made things happen.

Both sides of the table. I work where they meet.
Most projects stall between the people who want something and the people who build it. I’ve spent my career in that gap: from logistics operations and enterprise IT support to leading support teams and running technical operations for a high-growth payment orchestration platform.
