Hire the Best DevOps Engineers in Tunis, TN

Certifications: Linux Professionals Institute - LPIC-1 AWS Certified SysOps Administrator - Associate AWS Certified DevOps Engineer - Professional I am a Senior DevOps / Cloud Infrastructure Engineer specializing in AWS architecture, production reliability, compliance readiness (SOC 2 / ISO 27001), and scalable multi-environment infrastructure. I help startups and growing SaaS companies stabilize, secure, and scale their AWS environments — often stepping in to audit, fix, and modernize existing infrastructure. To date, I have: • Designed and restructured multi-account AWS environments (dev/staging/prod isolation) • Built and maintained ECS Fargate production clusters • Migrated legacy servers to containerized workloads • Implemented Terraform-based Infrastructure as Code across multiple organizations • Led SOC 2 readiness initiatives including security hardening and risk remediation • Recovered unstable production systems under live traffic AWS Architecture (Advanced) • Multi-account architecture (Organizations, SCPs, IAM boundaries) • ECS Fargate, EC2, ALB/NLB, Auto Scaling • RDS (Aurora Serverless v2), MySQL/Postgres optimization • S3, CloudFront, WAF, Route53 • VPC design, subnet isolation, NACL hardening • Secure parameter management (SSM, Secrets Manager, KMS) • CloudWatch monitoring, alerting, log aggregation DevOps & Automation • Terraform (modular, environment-aware design) • GitHub Actions & CI/CD architecture • OIDC-based GitHub → AWS authentication • Ephemeral preview environments per PR • Blue/Green & zero-downtime deployments • Docker production optimization • Cost optimization & AWS spend audits Security & Compliance • SOC 2 Type I / II preparation • IAM least-privilege design & MFA enforcement • Encryption at rest & in transit (KMS, TLS policies) • Secrets rotation & audit logging • Risk assessments & remediation roadmaps • Security architecture documentation Databases & Data Operations • Production MySQL / Postgres migrations • CouchDB clustered deployments (n=3, q=8) • Shard recovery & disaster recovery planning • Backup validation & restore testing • Schema migrations (Alembic, Laravel, etc.) I do not apply superficial fixes. I audit environments thoroughly, document risk exposure, and implement long-term infrastructure improvements designed for scalability, security, and operational clarity. If you need a senior-level DevOps engineer who understands production systems, compliance pressure, and business continuity, I would be glad to assist.

Self-driven DevOps engineer who builds and runs infrastructure that works when it matters. I've spent years working with Kubernetes, OpenShift, and Linux systems in production environments where downtime isn't an option (Banking Sector). I handle the full stack: cluster setup and operations Day0-2, infrastructure automation with Terraform and Ansible, CI/CD pipelines, and production troubleshooting when things break. I work across AWS, Azure, and on-prem environments, and I'm comfortable with both greenfield builds and fixing what's already there. My background includes networking, security hardening, and Linux administration. I've architected and deployed Red Hat platforms like Ansible Automation Platform and Red Hat Satellite. I manage SSL/TLS certificates, configure load balancing, and handle DNS. I've also deployed self-hosted AI infrastructure including vector databases and RAG pipelines on Kubernetes. I write tools in Golang when the situation calls for it. I use monitoring and observability tools like Prometheus, Grafana, and Loki to catch issues before they become incidents. I've built multi-tenant Kubernetes architectures with proper isolation, configured zero-trust networking with Wireguard, and integrated security scanning into CI/CD pipelines. I hold certifications from Red Hat, AWS, and the Linux Foundation, but what matters more is that I can diagnose problems quickly, communicate clearly, and stay engaged through tough situations. If you are looking for someone who can own infrastructure end-to-end and keep systems stable, let's talk.
