Summary
👤
Senior🎓
Top SchoolJustin Wienckowski is a Senior Software Engineer in San Francisco with over two decades of hands-on experience spanning cloud backends (GCP, AWS), APIs, iOS and React Native mobile, Django and Rails web apps, DevOps, cryptography, and automated testing. He has repeatedly shifted tech focus—14 years in J2EE/Rails, a move into iOS in 2012, and a backend/cloud comeback in 2019—demonstrating adaptability across startups and large teams like Amazon, Yelp, and Chime. At Whisper he bootstrapped backend services and multi-environment GCP infrastructure via Terraform, Helm, and Kubernetes while helping establish HIPAA-compliant operations; at Amazon he delivered measurable performance wins (40% faster app launch) through architectural refactoring. Known for pragmatic engineering and mentorship (his team nicknamed him “Winky-pedia”), he balances deep systems thinking with product-driven execution and a curiosity for new technologies such as Docker and infra-as-code. He also brings practical security and disaster-recovery experience from regulated environments and an appetite for explaining non-obvious concepts like the birthday paradox.
