Top SchoolLukasz Grabski is a seasoned software engineer and architect based in Krakow with over two decades of commercial experience and a dozen years in senior technical roles. He has repeatedly led greenfield migrations and modular DDD designs, most recently driving C#→Java migrations and building teams and architectures using Java 21, Spring Boot, Kubernetes, Kafka and cloud platforms. Lukasz blends hands‑on coding with system-level thinking informed by General Systems Theory, signal processing concepts and meticulous documentation practices (C4/Structurizr, ADRs). He has shepherded multi-team deliveries across domains from transportation IoT and TV/multimedia to finance, telecom and e‑learning, often taking first‑engineer or lead roles on complex platforms.
