Top Rated Plus, top 1% on Upwork, 10+ years running production infrastructure for US companies. I am a DevOps and cloud infrastructure engineer. I design, automate, and run production environments on AWS, GCP, and Azure, and I take teams from manual deployments and "it works on my machine" to a repeatable, monitored, cost controlled platform they can ship to every day. Most of my clients come back for a second and third engagement, and many of the long running ones started as a single small task. I would rather tell you a scope is unrealistic before we start than discover it together halfway through. 𝗪𝗵𝗮𝘁 𝗜 𝗱𝗼 ▸ Cloud infrastructure: AWS (EKS, ECS, Fargate, Lambda, VPC, IAM, Aurora, RDS, S3, CloudFront), GCP (GKE, Cloud Armor, managed databases), Azure (Azure DevOps, AKS), Oracle Cloud ▸ Kubernetes: cluster design and management, Helm charts, HPA autoscaling, NGINX and Traefik ingress, Rancher, multi environment setups on GCP and AWS ▸ Infrastructure as Code: Terraform, Ansible, AWS CloudFormation, Puppet, Chef ▸ CI/CD: GitHub Actions, GitLab CI, Jenkins, CircleCI, Azure Pipelines, AWS CodePipeline, CodeBuild, CodeDeploy, TeamCity ▸ Monitoring and observability: Prometheus, Grafana, ELK, CloudWatch, New Relic, Nagios, Telegraf, InfluxDB, alerting and on call runbooks ▸ Security and compliance: HIPAA and SOC 2 aligned infrastructure, IAM hardening, VPN, network segmentation ▸ Migrations: on prem and VMware workloads to cloud, monoliths to containers, performance tuning and cost reduction after the move ▸ Linux and scripting: RHEL and Ubuntu administration, Bash and Python automation 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 𝘀𝘂𝗽𝗽𝗼𝗿𝘁 I also write backend code (Python with Flask and Django, Go, JavaScript/TypeScript, Java) when the infrastructure work needs it. That means I can fix the application side of a deployment problem, build internal tooling, or wire up serverless functions myself instead of handing it back to your developers. 𝗪𝗵𝗲𝗿𝗲 𝗜 𝗵𝗮𝘃𝗲 𝗱𝗼𝗻𝗲 𝘁𝗵𝗶𝘀 ▸ Zazmic Inc, San Francisco: GCP platform built on Terraform and Ansible, GitLab CI pipelines, Helm based deployments, Cloud Armor and HPA for resilience ▸ Tripleseat, Concord MA: Azure and GCP environments, Azure DevOps pipelines, Docker, Grafana and Prometheus monitoring ▸ Century Communities, Greenwood Village CO: AWS and Oracle Cloud, ECS and EKS workloads, CircleCI, GitHub Actions and CodePipeline, Lambda and Ansible automation, CloudWatch 𝗪𝗵𝘆 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝘀𝘁𝗮𝘆 ▸ Honest scoping: you get a written scope, timeline, and the risks I see before any hours are billed. If something is out of my depth I say so. ▸ Your infrastructure stays yours: everything lives in your accounts and your repos, with documentation and handover notes so nobody depends on me to keep the lights on. ▸ Steady communication: regular progress updates in your channel of choice, no long silences, no surprises on the invoice. ▸ Production mindset: I treat your environment like I am on call for it, because during our engagement I am. That includes off hours incident response and 15 days of free support after delivery. ▸ Verifiable track record: Top Rated Plus with a 100% job success score, and I am happy to connect you with past clients for a reference.
