Top SchoolRafal Plinzner is a Senior Software Engineer based in Stockholm with 8 years of experience building backend systems primarily in Node.js and TypeScript. He has a strong track record delivering GraphQL-driven, containerized services (Docker) across domains including fintech, healthcare, public procurement and airport operations, and is currently contributing at Klarna. Rafal pairs solid computer science foundations (MSc) with hands-on expertise in distributed patterns—RabbitMQ, Redis, microservices and federation—bringing reliability to real-time and transactional platforms. He’s comfortable across the stack from API design to data persistence (MySQL/Postgres) and testing, and has run his own development business, which sharpened his product and client-facing instincts.
