AWS DevOps & Infrastructure Engineer | Docker · Linux · CI/CD · NGINX

I build AWS cloud infrastructure, Linux server environments, and CI/CD pipelines for startups and SaaS companies that need reliable production systems and faster deployments. From provisioning and scaling cloud environments to automating deployments and migrating applications to AWS, DigitalOcean, or GCP — I handle the infrastructure work that keeps engineering teams unblocked and production systems stable. → Every invitation I receive gets a personalized Loom video — a short walkthrough of exactly how I’d approach your specific problem, before the contract starts. What clients bring me in for: • Cloud infrastructure — AWS EC2, ECS, EKS, RDS, Lambda, S3, CloudFormation, Elastic Beanstalk, Route 53 and DigitalOcean VPS provisioning, scaling, and ongoing management • Linux server administration — Ubuntu and CentOS setup, hardening, NGINX configuration, SSL/TLS, firewall rules, and server management • CI/CD pipelines — GitHub Actions, Jenkins, GitLab CI, AWS CodeDeploy so deployments stop being manual and error-prone • Containerization — Docker and Kubernetes for reproducible production environments that behave the same in staging and production • Infrastructure as code — Terraform and Ansible for automated, version-controlled provisioning and configuration management • Monitoring and observability — Grafana, Prometheus, ELK Stack, and Graylog so problems surface before clients notice them • Email infrastructure — Postfix, HAProxy, DKIM, SPF, DMARC, and SMTP hardening for reliable mail delivery at scale • Cloud migration — moving applications from shared hosting or on-premise to AWS, GCP, or DigitalOcean with minimal downtime Infrastructure I have built: Migrated a Laravel application to AWS Elastic Beanstalk with autoscaling — handles variable production traffic without manual intervention, deployed via CI/CD with zero-downtime releases. Set up VueStorefront in production with AWS Elasticsearch Service — replaced a local ELK stack, reduced infrastructure overhead, and improved search performance for a production e-commerce platform. Automated SSL and custom-domain provisioning for a SaaS platform using Let’s Encrypt, Docker containers, and auto-generated NGINX vhosts — customers connect via CNAME without sharing DNS credentials. Re-architected a legacy email infrastructure from CentOS 7 to Ubuntu 22.04 — hardened SMTP stack, centralized logging with Graylog and ELK, scaled to 20+ nodes with HAProxy failover and 5-second recovery time. Built GPU provisioning automation that spins resources up on demand, processes workloads, stores results, and releases them — cutting idle GPU costs close to zero. Before touching a server I plan for architecture, failover, security hardening, and documentation — so the environment runs reliably without me being on call for it. Every engagement ends with a documented system the client’s team can operate independently.
