Rockstar🎓
Top SchoolPaweł Kuffel is a pragmatic CTO and founder with eight years of hands-on experience building full-stack and cloud-native systems, currently leading engineering at Field Materials AI. He combines React/TypeScript front-end work with Node.js back-ends and relational/NoSQL databases, and brings a strong DevOps and microservices pedigree (Kubernetes, Kafka, RabbitMQ, EFK) to bridge product and platform. His progression from Senior Backend Developer to Backend Team Lead and now CTO reflects a track record of shipping resilient distributed systems under real-world constraints. An active open-source contributor, he implemented a latency-simulating TCP proxy in Go to test network behaviors, showing a focus on reliability and observability beyond feature work. Trained at Poznan University of Technology, he pairs formal software engineering education with entrepreneurial instincts from running iqcode.
