Quote of the Day

Kratik Jain
building cloud-native infrastructure and developer tooling. Currently leading infrastructure at Primetrace (Crafto/Kutumb App), serving ~4M daily active users with traffic peaks of 1M+ TPM.
I look after infrastructure, security and cloud cost, and lead a small infra team that I built. CKA (100/100), CKS certified, and AWS DevOps Engineer Professional.
When not automating infrastructure, you'll find me building open-source tools, blogging about DevOps, or exploring heritage sites on my bike.

Experience
- 2022 — now Infrastructure Lead | Primetrace (Crafto/Kutumb App)
Moved production from kOps to Terraform-managed EKS with Karpenter, scaling to ~800 nodes on festival days. Built our observability stack (VictoriaMetrics, Loki, Elastic APM, Langfuse), a DevSecOps pipeline with DefectDojo, SSO across internal tools and a NetBird VPN. Own cloud cost end to end, and hired and mentored the infra team.
- 2019 — 2022 Software Engineer | Cuelogic Technologies (LTI)
Automated infrastructure with AWS CloudFormation and Ansible, optimized CI/CD pipelines, migrated apps from bare metal to Docker Swarm, and contributed to Python projects across multiple domains.
- 2019 Intern | Cuelogic Technologies
Trained in Linux, Networking, Docker, and Kubernetes. Worked on a SOC tool ingesting TBs of logs daily, replicated prod clusters with Vagrant & Ansible, and debugged K8s issues.
