Summary
👤
Senior🎓
Top SchoolPiotr Szymanski is a Principal Engineer with 11+ years building and operating large-scale, secure platforms across startups and fintech, currently shaping infrastructure at Klarna. He bridges hands-on software, DevOps and SRE disciplines—shipping systems in Python, Go and TypeScript while owning observability, PKI, and self-healing control planes that serve thousands of engineers. His experience ranges from low-latency DSPs and CDC pipelines to designing company-wide container platforms with AWS CDK/CloudFormation and automated metrics/alerts by default. Piotr favors pragmatic simplicity: delivering the least complex solution that endures operational entropy, and he’s comfortable switching between developer and on-call hats. A background in building deploy pipelines, Terraform-managed infra, and PKI for fintech-grade security gives him a rare mix of product-scale engineering and production hardening.
