CHUKWULETA CHIGAEMEZU CHARLES

Enterprise Cloud Foundation (Project Bedrock)

Fulltime

Summary

Architected a production-ready, 3-tier AWS VPC environment (Public, Private, and Data subnets) using Terraform to ensure high availability and network isolation. Automated infrastructure lifecycle management by engineering GitHub Actions workflows for CI/CD, reducing environment provisioning time from hours to minutes. Implemented state management security using S3 Remote State and DynamoDB locking, ensuring team collaboration without configuration drift. Optimized cloud spend by integrating Terraform-based tagging and AWS Budgets, ensuring 100% visibility into resource allocation.

Deploying a Static Website on AWS with CI/CD

School project

Summary

Description: Designed and deployed a highly available web application on AWS Cloud using Infrastructure as Code (Terraform). Implemented a complete CI/CD pipeline with Jenkins and GitHub Actions, enabling automated builds, testing, and deployments. Containerized the application using Docker and orchestrated it with Kubernetes to ensure scalability and fault tolerance. Key Contributions: Built and managed cloud infrastructure (VPC, EC2, S3, RDS, Load Balancers) with Terraform. Automated server provisioning and configuration management using Ansible. Deployed containerized services with Kubernetes for load balancing and scaling. Integrated monitoring and logging with Prometheus and Grafana for real-time visibility. Secured the infrastructure with IAM roles, SSL/TLS certificates, and firewalls. Outcome: Reduced deployment time by 70% through automation. Achieved zero-downtime deployments and improved system reliability. Enhanced team collaboration and code quality through version control and automated testing.

high-availability Three-Tier Architecture on AWS for TechCorp.

Hands-on

Summary

The infrastructure provisions a Virtual Private Cloud (VPC) with public and private subnets across two Availability Zones. It includes: Networking: VPC, Public/Private Subnets, Internet Gateway, NAT Gateways, and Route Tables. Security: Security Groups for Bastion, Web Servers, Database, and Load Balancer. Compute: Bastion Host: For secure SSH access. Web Servers: 2x EC2 instances (Apache) in private subnets. Database Server: 1x EC2 instance (PostgreSQL) in a private subnet. Load Balancing: Application Load Balancer (ALB) distributing traffic to web servers.

Summary

Architected a "Security-First" cloud environment on AWS using a Modular Terraform approach. The project involved setting up a multi-tier networking layer, containerizing a backend service, and automating the entire deployment lifecycle through GitHub Actions. By separating Infrastructure-as-Code (IaC) from Application code, I established a scalable DevSecOps workflow that ensured consistent, repeatable deployments.
