Pelle Frank is a Principal Engineer based in Stockholm with 14 years of experience building scalable, product-focused systems at the intersection of data, product, and engineering. He has repeatedly taken services from zero to massive scale—most notably growing a backend to 5 million monthly active users and designing a cost-efficient architecture that handled spikes up to 1M requests per minute. A long-time founder and former CTO, Pelle blends hands-on implementation (backend, infra, data, and front-end test automation) with technical leadership, coaching cross-functional teams and shaping security and compliance practices. He is comfortable across AWS-native and serverless architectures, modern data stacks (dbt, ELT, S3/Glue/Athena) and shipping pragmatic IaC using AWS CDK. Quietly strategic, he has a track record of hiring and transitioning into roles where successors can flourish while he focuses on high-leverage individual contribution and platform reliability.
