πŸ‘¨πŸ½β€πŸ’» O Jegede – DevOps | DevSecOps | Cybersecurity Analyst | Cloud Security Engineer

Hi there! πŸ‘‹ I’m O Jegede, a passionate and hands-on DevOps & DevSecOps Engineer and Cybersecurity Analyst with a growing portfolio of real-world projects focused on secure cloud infrastructure, CI/CD automation, identity and access management (IAM), and threat detection.

With a background in both cloud engineering and cybersecurity, I build systems that are not only scalable and automated β€” but also secure by design.


πŸ” My Security-First DevOps Mindset

From automating pipelines to hardening infrastructure, I approach DevOps with a cybersecurity lens. Whether it’s integrating static code analysis into a Jenkins pipeline or deploying an intrusion detection system (IDS) alongside a Kubernetes cluster β€” I ensure that security is baked into every layer.


πŸ›  Core Domains

  • DevOps & CI/CD Pipelines: Jenkins, GitHub Actions, Docker, Terraform, Kubernetes (EKS), AWS
  • DevSecOps: SAST/DAST, container scanning, compliance-as-code, shift-left security
  • Identity & Access Management: Role-based access control, SSO, MFA, policies using Okta, AWS IAM, and OAuth 2.0
  • Cybersecurity Operations: Vulnerability management, SIEM, IDS/IPS, malware analysis, threat detection
  • Monitoring & Logging: Prometheus, Grafana, Wazuh, Elastic Stack

πŸ›‘ My DevOps and DevSecOps Projects

Here's a curated list of projects I’ve completed as part of my DevOps and DevSecOps professional journey. Each project is built to replicate enterprise environments and solve real-world infrastructure, security, and automation challenges β€” using cutting-edge tools and best practices.

πŸ§ͺ Infrastructure as Code (IaC)

Automated provisioning and configuration of cloud-native resources using reusable, version-controlled IaC templates.

  • Terraform Modules – Modularized VPCs, EC2s, IAM policies, ALBs, RDS, and S3 across environments
  • CloudFormation Templates – Scalable infrastructure stacks using YAML and cross-stack references
  • Secure IaC Pipelines – Policy-as-code integration with tools like OPA and Checkov for early IaC scanning

☁️ Cloud Environments (AWS)

Cloud-native development and infrastructure orchestration for high availability, scalability, and resilience.

  • 3-Tier Architecture – Web/App/DB stack deployed on AWS using Terraform and EC2/RDS/ALB
  • IAM & Role-Based Access – Secure IAM roles, policies, and MFA enforcement
  • Secrets Management – Using AWS Secrets Manager + environment-specific configurations

πŸ” CI/CD Automation

End-to-end pipelines for automated builds, testing, security checks, and multi-env deployments.

πŸ”§ Jenkins Pipelines

  • Declarative multi-stage pipelines for container builds, vulnerability scanning, and multi-environment deployments
  • Integrated SonarQube for SAST, Snyk for SCA, and Trivy for container scans
  • Slack and email notifications on pipeline events and failures

πŸ›  GitLab CI/CD

  • Secure GitLab runners executing IaC validation, container builds, and Helm/Kustomize-based Kubernetes rollouts
  • Integrated Vault secrets injection and DAST testing for web applications
  • GitOps-style workflows for merging changes into staging β†’ production via protected branches

☸ Kubernetes Deployments

Hands-on experience deploying secure, production-grade workloads on Kubernetes using GitOps and IaC strategies.

  • Helm Charts – Package, version, and release microservices with dynamic configuration
  • Kustomize Overlays – Managed multi-environment deployments (dev, stage, prod) using overlays and patching
  • EKS Clusters – Deployed and managed AWS EKS clusters using Terraform
  • RBAC Policies – Controlled access per namespace and role using Kubernetes RoleBindings

πŸ” DevSecOps Integration

Security-first automation ensuring security is not an afterthought.

  • Pre-Commit Hooks – Enforced secret detection and linting before PRs are merged
  • Container Security – Docker image scanning with Trivy, Grype, and Clair
  • Policy-as-Code – OPA & Rego used to define and enforce deployment and RBAC policies in CI
  • Audit Logging – Kubernetes audit logs and AWS CloudTrail for traceability and compliance

πŸ“ˆ Monitoring & Observability

Built full-stack observability pipelines to monitor applications and infrastructure health.

  • Prometheus + Grafana – Monitored Kubernetes pods, node health, and custom app metrics
  • ELK Stack – Centralized log analysis from EKS, Lambda, and EC2
  • AlertManager – Real-time alerts on resource exhaustion, failed deployments, or SLA violations
