Dennis Holmer is a senior software engineer and engineering leader based in Stockholm with over a decade of hands-on experience building cloud-native, serverless systems and integrations. He has led engineering teams and launched products from prototype to scale—from co-founding and serving as CTO at Zwapgrid to heading multiple product engineering efforts as SVP at Trilogy. Recently he’s focused on fintech infrastructure and banking/card product engineering in AWS, and now advises as a senior cloud architect while contributing to YC-backed Anima. Dennis blends deep backend expertise (C#, .NET Core, AWS, Azure, Kafka, Kubernetes, Terraform) with a track record of shipping complex integrations and automation. He is comfortable switching between strategic architecture and writing production code, and has repeatedly built teams and developer workflows that accelerate delivery. Outside day-to-day roles he brings an entrepreneurial mindset evident from early product sales and sustained startup founding experience.
