Summary
👤
SeniorJanusz Piechówka is a Senior Software Engineer based in Krakow with 10 years of experience building cloud-native, microservice-based systems and tooling across Go, Python and Java. He blends hands-on backend development and Kubernetes/GKE operations with practical security skills honed through penetration testing, reverse engineering and source code audits. At Form3 and previously at Acaisoft and Brown Brothers Harriman he has delivered CI/CD pipelines, maintained production services on AWS/GCP, and contributed to both ML and distributed applications. His background as an IT security consultant means he routinely designs defensive measures informed by offensive techniques, and he has built custom offensive tooling and Burp extensions to support testing. Colleagues describe him as someone who deliberately disassembles systems to understand them end-to-end, turning curiosity about low-level behavior into more secure, maintainable software.
