Summary
👤
Senior🎓
Top SchoolAndrzej Wierzbanowski is a Senior Software Engineer based in Katowice, Poland, with about a decade of hands-on experience building backend systems and developer tooling. He has delivered production-grade microservices and real-time features at companies like Zendesk and Brainly, working across Go, Node.js, TypeScript, GraphQL and AWS to ship resilient, scalable platforms. Andrzej combines product-facing engineering—React frontends and realtime channels—with deep infrastructure work around CI/CD, Kubernetes, observability and incident post-mortems. He’s contributed to ad tech, news platforms, and edtech, often driving architectural changes via ADRs/RFCs and maintaining technical debt roadmaps. A regular mentor and recruiter, he accelerates teams through onboarding, code reviews and workshops. Less obvious: he pairs customer-focused feature work with low-level performance and caching optimizations that keep high-traffic sites reliable.
