Cloud Native WebApp

Production-Grade GCP Infrastructure with CI/CD

// The Challenge

Building Production-Ready Cloud Infrastructure

Organizations need secure, scalable cloud infrastructure that combines Infrastructure as Code, automated CI/CD pipelines, and production-grade security - all while maintaining cost efficiency and deployment velocity.

Challenge 1
Manual infrastructure provisioning slows deployment cycles
Challenge 2
Lack of automation in testing and deployment workflows
Challenge 3
Insufficient observability and security hardening

// My Role

DevOps Engineer & Infrastructure Architect

Designed and implemented the complete cloud infrastructure on GCP using Terraform, built automated CI/CD pipelines with GitHub Actions, created custom machine images with Packer, and established production-grade observability, security, and auto-scaling capabilities.
