Hi, I’m Juho Päivärinta from Tampere, Finland. I’m a vision-driven DevSecOps engineer with nine years of experience building secure, scalable hybrid‑cloud platforms and data pipelines that power AI and autonomous systems. I’ve designed and deployed infrastructure that supports a fleet of 500+ autonomous vehicles and processes over 100 TB of sensor and log data daily. I thrive at the intersection of security, cloud, and data engineering. I enjoy collaborating with cross‑functional teams to implement declarative infrastructure, automate provisioning, and enforce Zero Trust across distributed environments. I’m passionate about applying open‑source tooling and cloud‑native services (AWS, Azure, GCP, Kubernetes, Terraform, Python, Go) to deliver robust, measurable improvements in security, reliability, and efficiency.…Hi, I’m Juho Päivärinta from Tampere, Finland.
