Top SchoolSebastian Korfmann is a product-focused software engineer and founder with 15 years of experience building developer-facing tools and cloud-native platforms, currently co-creating Agentic Hamburg and running multiple ventures from Hamburg, Germany. He led the creation and launch of the CDK for Terraform—now a prominent open-source project—then scaled it as technical lead at HashiCorp, blending hands-on engineering with team building and cross-company collaboration. Sebastian spans frontend to backend and DevOps, with deep experience in serverless and cloud architectures (AWS, Cloudflare) and practical monorepo and CI tooling. He enjoys direct user and customer engagement, using feedback to shape product direction and developer experience. A keen explorer of agentic software and LLM-driven workflows, he builds bridges between emerging AI capabilities and production-ready developer tools despite not coming from a formal ML background. His career mixes consulting, community-building (cdk.dev, CDK Weekly) and product launches, revealing a pattern of turning prototypes into widely adopted platforms.
