Backend engineer specialising in distributed, event-driven systems — commands and events in real time, eventual consistency done deliberately, not accidentally.
Fintech and marketplaces: banking event backbones, order pipelines, catalog trees with 40,000+ nodes. I design inter-service communication strategies, review code, and have led a backend team.
