01 · about

Infrastructure, treated like a product.

Documented, tested, and continuously improved — the same way good software is built.

I'm a DevOps Engineer at Codeace IT Solutions LLP, where I architect AWS infrastructure from scratch, build multi-environment CI/CD pipelines, and automate away the repetitive.

I manage AWS (EC2, ECS, ECR, RDS/PostgreSQL, Lambda, Cognito, IAM, VPC, CloudWatch), harden production Linux, and run observability with Zabbix and CloudWatch — keeping deployments safe and fast.

RHCSA certified. Kubernetes-curious. Continuously learning, shipping, and improving.

Automate the toil

Bash and Ansible for anything done twice — provisioning, backups, migrations.

Secure by default

UFW, key-only SSH, enforced SSL and hardened Nginx on every server.

Observe everything

Zabbix and CloudWatch alerting, log analysis and fast incident response.

  1. DevOps Engineer

    Codeace IT Solutions LLP · Kozhikode, Kerala

    Dec 2024 — Present
    • Built a production AWS platform end-to-end — ECS, ECR, RDS/PostgreSQL, Lambda and Cognito, with automated Dev/Demo/Prod deployments via GitHub Actions.
    • Ran multi-site hosting on DigitalOcean and executed full server migrations — DNS cutover, SSL re-provisioning and performance tuning.
    • Administered AWS for high availability — EC2, S3, VPC, RDS, IAM and CloudWatch, including security groups and network access.
    • Built CI/CD with GitHub Actions and GitLab CI/CD and managed Git branching strategies across teams.
    • Automated deployment workflows and server ops with Bash and Ansible.
    • Hardened Linux servers — Apache/Nginx, UFW firewall rules, key-only SSH and enforced SSL.
    • Monitored with Zabbix and CloudWatch — log analysis, patching and incident troubleshooting; containerized services with Docker while learning Kubernetes.

Multi-Env AWS Infra & Delivery

Production platform with fully automated AWS infra and multi-environment delivery.

  • AWS infra from scratch — ECS, ECR, RDS/PostgreSQL, IAM, VPC, CloudWatch
  • CI: format, lint, type-check and build, plus tests against a live PostgreSQL service container
  • CD: Docker images pushed to ECR tagged by SHA, auto-deployed per branch with concurrency controls and Slack notifications
  • Cognito + Lambda triggers for auth, targeting linux/amd64 for Lambda
  • ECS
  • ECR
  • RDS
  • Cognito
  • Lambda
  • GitHub Actions
02

Server Hardening & Security Baseline

A repeatable, automated security baseline for production Linux across environments.

  • UFW rules, security groups, disabled root login and key-only SSH
  • Automated SSL provisioning and renewal with Bash
  • Hardened Nginx — security headers, no server tokens, enforced HTTPS redirects
  • Linux
  • UFW
  • Nginx
  • SSL
  • Bash
03

Server Automation & Migration Toolkit

Tooling that removes toil and de-risks server moves.

  • Bash for user provisioning, log rotation, disk alerts, service restarts and backups
  • Migration scripts for file transfers, database dumps and environment setup
  • Standardized runbooks so provisioning is repeatable
  • Bash
  • Ansible
  • Linux
