I cut a production video pipeline's cloud bill from ~$18k to ~$1.8k/month, run a 24-service Kubernetes fleet on AWS EKS, and led a zero-downtime Azure → AWS migration. ~5 years building backend systems at scale: Ruby on Rails, Go, NestJS, real-time messaging, media pipelines, GitOps (Helm, Flux/ArgoCD, Karpenter, KEDA) and self-hosted GPU/ML services. Book a call if: • Your cloud bill is growing faster than your users • Your backend is slow, flaky or hard to scale • You're moving to Kubernetes / AWS or planning a migration • You're building an MVP and want the architecture right the first time • You're preparing for senior backend / system design interviews You'll leave every call with concrete next steps, not generic advice. Need hands-on help after the call? I take fixed-scope projects too. Portfolio: manikantagopi.com
