Hi, I'm Abhishek Singh 👋

DevOps Engineer · SRE · Platform Engineer — 3 years of production infrastructure experience at Lloyds Banking Group, one of the UK's most regulated banking environments.

I build CI/CD pipelines developers trust, Kubernetes clusters that stay up, Terraform infrastructure that doesn't drift, and Python automation that eliminates work that should never have been manual.

🚀 Featured Project

A production-grade platform built from scratch.

  • AWS infrastructure via Terraform — VPC, EKS, RDS, S3, IAM, CloudFront, Lambda, SNS/SQS — zero ClickOps
  • Full CI/CD on Jenkins + GitHub Actions — Docker builds, ECR push, Helm deploy to EKS, auto rollback on failure
  • 3-tier microservices on Kubernetes — HPA auto-scaling, rolling updates, liveness/readiness probes
  • Full observability — Prometheus + Grafana (SLI/SLO dashboards), Alertmanager, ELK log aggregation
  • DevSecOps — IAM scoped roles, K8s RBAC, secrets isolation, automated security scanning in pipeline

💼 Experience

DevOps Engineer / Operations Analyst @ Lloyds Banking Group (Mar 2022 – Jan 2025)

  • Designed and built end-to-end CI/CD pipelines on Jenkins and GitHub Actions — commit to production, zero manual steps
  • Authored Terraform modules covering VPC, EC2, EKS, IAM, RDS, ELB, S3 — reusable across teams, environment drift eliminated
  • Owned EKS clusters in production — Helm charts, RBAC, network policies, pod-level fault isolation
  • Implemented observability stack (CloudWatch, Prometheus, Grafana, ELK) — every alert actionable, on-call noise reduced
  • Passed banking-sector security audit without a single finding
  • Wrote runbooks detailed enough that junior engineers resolved incidents independently
