𝟮𝟬𝟬+ production servers managed, 𝟱𝟬𝟬+ smaller migrations completed, 𝟮𝟱+ full infrastructure migrations to cloud platforms, and 𝟯𝟬+ mail servers re-architected — that is the track record behind my 𝟳+ years as a Cloud & DevOps Engineer. On Upwork, I have logged 𝟮,𝟱𝟱𝟰 hours across 𝟱𝟱 contracts, hold Top Rated status, and keep a 𝟭𝟬𝟬% Job Success Score, working with SaaS companies, startups, and AI businesses that need someone to take real ownership of AWS infrastructure, CI/CD pipelines, Docker and Kubernetes environments, and production systems — not just deploy a server and walk away. Clients typically bring me in when they need to: • Build or scale AWS production infrastructure using EC2, ECS, EKS, Lambda, S3, RDS, CloudFormation, CloudWatch, and Route 53 • Set up and optimize CI/CD pipelines with GitHub Actions, Jenkins, or GitLab CI to cut release time and deployment risk • Containerize and orchestrate applications with Docker and Kubernetes for predictable, repeatable deployments • Provision and manage infrastructure as code using Terraform and Ansible instead of manual, error-prone setup • Migrate applications, databases, and mail servers to AWS, Google Cloud Platform, or Microsoft Azure with minimal or zero downtime • Administer Linux System Administration environments (Ubuntu, Debian, CentOS, AlmaLinux) and harden NGINX-based production stacks • Set up monitoring and observability with Grafana, Prometheus, and the ELK stack so issues get caught before customers notice • Deploy and scale AI and GPU workloads on demand to control infrastructure costs • Manage Azure DevOps and AWS DevOps pipelines across mixed multi-cloud environments • Reduce unnecessary cloud spend while improving reliability, backups, and security posture I focus on business outcomes, not infrastructure for its own sake — choosing an architecture that is reliable and scalable without adding operational complexity or cost that nobody asked for. Some of the infrastructure I have worked on: • Migrated a Laravel production application to AWS Elastic Beanstalk with autoscaling to absorb changing production workloads without manual intervention. • Built an automated GPU provisioning platform that spins up rented GPU resources on demand, distributes processing across available compute, stores the results, and releases resources afterward — cutting idle GPU costs close to zero. • Re-architected a legacy email infrastructure end to end: migrated CentOS 7 to Ubuntu 22.04, hardened SASL and TLS across the full SMTP stack, built centralized logging with Graylog and the ELK stack, and scaled the system to a couple thousand emails per day across 20+ nodes with roughly 5-second HAProxy failover. • Deployed high-availability Ray clusters for distributed AI computing alongside a full observability stack (Prometheus, Grafana, ELK, Graylog) that shortened incident response time significantly. • Automated custom-domain and SSL provisioning for a SaaS platform using Let's Encrypt, short-lived Docker containers, and auto-generated NGINX vhosts — customers connect a domain via CNAME without ever sharing DNS credentials. • Built a fully automated remote-desktop provisioning system with AWS Lambda, EC2, and Apache Guacamole running inside Docker Compose for consistent, repeatable deployment. When I take on a migration, I look past just moving files to a new server. I plan for architecture, DNS, SSL, databases, backups, deployment, monitoring, security, and rollback, so the environment is easier for your team to operate long after I'm gone. I'm equally comfortable joining an existing engineering team or taking full, long-term ownership of a client's production environment — investigating incidents, automating operations, and maintaining high uptime. Core expertise: AWS • DevOps • Docker • Kubernetes • CI/CD • Terraform • Ansible • Google Cloud Platform • Microsoft Azure • Azure DevOps • Linux System Administration • NGINX • Ubuntu • Cloud Migration • AWS Lambda • AWS CloudFormation • Grafana • GitHub • Site Reliability Engineering • Infrastructure Automation If you need an engineer who combines hands-on infrastructure experience with a business-focused approach to reliability, scalability, and cost control, I can help you build, migrate, secure, or take ownership of your production environment — starting with a clear plan, not guesswork. I communicate clearly, document what I build, and treat your infrastructure as a critical part of your business, not just another ticket to close.
