What I'm looking for

I'm looking for complex, non-standard product challenges where I can build scalable full-stack systems, shape architecture, mentor engineers, and work closely with stakeholders to deliver practical results.

I've built and modernized production web platforms for PowerOffice, CIBC, ReadyDev Technologies, and RecoverUA. At PowerOffice, I architected a strangler-fig migration from a 20 MB Ext.js SPA to React while preserving unified state and avoiding direct legacy dependencies.

Across fintech, banking, developer marketplaces, logistics, and humanitarian products, I've delivered React and Node.js systems, high-load document pipelines, real-time collaboration tools, and third-party data integrations. I enjoy complex, non-standard problems, and I combine hands-on architecture with technical mentorship, backlog prioritization, and close collaboration with stakeholders.
