What I'm looking for

Senior Backend Engineer (Node.js/TS) with practical Next.js/React skills for end-to-end tasks. Looking for a mature SaaS/product company with a healthy, async culture in European time zones. I value clean architecture (DDD, Hexagonal), TDD, and solid engineering. No interest in early-stage chaos, deep-tech micro-optimizations, or US time zone overlap

Backend engineer with 6 years at Prisjakt, a Swedish price comparison platform. I specialize in Node.js and TypeScript, mostly working on data-heavy systems – pipelines processing 100k+ records, Kafka-based infrastructure, and microservices on GCP. I'm comfortable across the stack (Next.js, GraphQL, SSR) but my strongest suit is backend and data engineering. Currently open to remote or hybrid (Kraków/Katowice) opportunities at product companies with a strong engineering culture.

Core stack: Node.js · TypeScript · Kafka · GCP · PostgreSQL/MySQL · Next.js · Docker
