> Data_Center_Management

• Infrastructure Management: Maintained high availability and performance for a hybrid environment housing 50+ virtual machines running critical services on both Linux (Debian/RHEL) and Windows Server platforms.
• Monitoring Implementation: Engineered and deployed a centralized monitoring system for real-time tracking of server health, network latency, and resource utilization, resulting in a 75% reduction in reactive maintenance time.
• Regional Office Deployment: Established core network infrastructure for Headquarters and the West African regional office by deploying a firewall for secure perimeter defense and an Active Directory equivalent for user authentication, achieving enterprise-grade security using cost-effective open-source solutions.

> DevOps_Implementation

• CI/CD Pipeline Setup: Engineered and maintained end-to-end CI/CD pipelines using Jenkins jobs triggered by commits to GitHub repositories.
• Automation Focus: Automated critical build, test, and deployment stages, reducing manual error and cutting deployment cycle time by over 85% (from ~3 hours manual to ~15 minutes automated).
• Process Improvement: Facilitated collaboration between development and operations by introducing structured Git flow practices and implementing Infrastructure as Code (IaC) for environment consistency.

> Data_Visualization_Deployment

• Containerization Strategy: Led containerization of multiple data visualization applications.
• Deployment Efficiency: Packaged applications and dependencies into immutable images to ensure 100% parity across development, testing, and production.
• Scaling & Orchestration: Used Docker Compose for multi-container setups and established a foundation for future orchestration migration to improve resilience and horizontal scaling.

> Security_Hardening

• Server Hardening: Performed rigorous hardening across production servers following benchmarks and best practices, disabling unnecessary services and tightening access controls.
• Intrusion Detection Management: Managed and tuned two IDS platforms to monitor network traffic for malicious signatures and anomalous behavior.
• Proactive Threat Mitigation: Developed custom detection rules tailored to the environment, successfully identifying and mitigating critical security alerts weekly to protect against unauthorized access and exploits.
