I'm a DevOps / SRE engineer who runs production solo for 50,000+ users. I migrated our platform from DigitalOcean to AWS, and day to day that's Infrastructure as Code, CI/CD, and observability — keeping production fast, reliable, and cheap — on a Node.js / TypeScript foundation that lets me fix things at the code level, not just the infra.

Experience

Mar 2025 - Present

RegisterKaro (Safe Ledger Pvt Ltd)

DevOps / Site Reliability Engineer

  • Migrated production from DigitalOcean to AWS with zero downtime — the full stack as code (Terraform/Ansible, multi-AZ, private subnets) for 50,000+ users.
  • Cut infrastructure cost ~20% via region co-location, VPC peering, and a database tier downgrade.
  • Right-sized the production MongoDB cluster a full tier (M50 → M40) — slow-query and index work reclaimed ~43% of slow-query time.
  • Built GitHub Actions CI/CD with blue-green deploys and automated rollback, plus Grafana/Loki/Promtail observability.
  • Led the platform's security & compliance program as sole DevOps lead — an ISO 27001:2022 remediation across 175 controls, a ~115-repo security audit, and live AWS hardening (CloudTrail, GuardDuty, KMS, least-privilege IAM).
  • Own production reliability end-to-end — root-causing live production incidents, ending recurring outages, and authoring the platform's SLA, runbooks, and hardening standards.
