Alexander Ortenburger
@alexanderortenburger
I build AI, fintech, and cloud platforms from architecture to production.
What I'm looking for
I've co-founded three companies and led end-to-end engineering for fintech, AI, and cloud platforms. At cashbuzz, I built a mobile and web fintech platform for major German banking partners, rearchitecting microservices to reduce cloud costs by 25% while maintaining reliability.
I'm currently leading technology strategy for Comeso's cross-border health payment platform and building serverless GenAI video pipelines at DEEPWERK on AWS. I pair deep systems work—including AI/ML, payment security, compliance, and cloud infrastructure—with customer-facing collaboration and engineering leadership.
