👤
SeniorPatryk Kozłowski is a Senior Developer with nine years of experience building high-throughput Node.js systems and developer tooling from Lublin, Poland. He has designed and operated real-time price streaming pipelines, robust ETL for regulatory filings, and resilient retry/backoff and observability patterns that keep downstream SLAs stable. As a founding engineer he built a fast SEC parser and NLP extractors, backend services handling 60k daily users, payments integrations, and internal apps that cut operational friction.

Currently expanding into Go, he pairs deep backend expertise with a taste for design and practical automation.
