About

DevOps Engineer | CI/CD & Automation Expert

Dedicated to eliminating manual overhead through robust automation and cloud-native strategies. From provisioning multi-tier VPCs with Terraform to orchestrating containerized microservices on EKS, I focus on building delivery pipelines that are fast, secure, and repeatable.

I view infrastructure through an entrepreneurial lens, balancing technical excellence with cost-efficiency and business impact. Whether it's migrating legacy workloads to the cloud or implementing GitHub Actions for seamless deployments, I build the "engine room" that allows software teams to ship code with confidence.

IAC

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.

Linux-Based User Management and File Access Control System
Linux-Based User Management and File Access Control System

🎯 Infrastructure / DevOps Practice Project

Summary

As a beginner cloud engineer, I built a Linux-based user and file management system to simulate real-world multi-user permission handling. The system uses Linux commands to: Create and manage multiple users (Mary, Joseph, and John) Assign different file permissions (Read, Write, Execute) using setfacl Use getfacl to verify permission states Implement user-based role simulation and access policies This project demonstrates my foundational skills in working with Linux systems, managing users, handling permissions securely, and preparing for cloud-based system roles.

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.
