I'm Anton Osenenko, a DevOps Platform Engineer based in Warsaw, Poland. With 15+ years in software development and deep infrastructure experience, I build cloud-native, automated, and production-grade systems.
I design AWS infrastructures from scratch, migrate systems to Kubernetes, and build CI/CD pipelines that scale. My focus is on clarity, automation, and reliability - from Terraform modules and CDKTF setups to real-time pipelines and observability stacks.
- Design and codify infrastructure with Terraform & CDKTF
- Build reproducible, compliant cloud platforms on AWS
- Automate CI/CD and deployment workflows
- Optimize observability and incident response
- Keep systems efficient, secure, and reliable
