PROFESSIONAL SUMMARY
Versatile Infrastructure and Automation Engineer with 4.5+ years of practical experience across DevOps, Cloud Infrastructure
(AWS), and Quality Engineering (SDET). Proven track record in provisioning reproducible cloud and staging environments using
Terraform and Ansible, containerizing workloads with Docker, and architecting fast, reliable CI/CD pipelines in GitHub Actions and
Azure DevOps. Transitioned from a QA Tech Lead managing a 19-engineer department into DevOps, bridging the gap between
development and operations through automated test infrastructure, server hardening (Linux, Nginx, UFW), and system
monitoring (Prometheus, Grafana).
CORE TECHNICAL SKILLS
Cloud & Infrastructure as Code (IaC): AWS (EC2, S3, VPC, Security Groups), Terraform (Modular VPS/Cloud Provisioning),
Ansible (Playbooks, Server Baselines & Configuration Management).
Containerization & CI/CD: Docker, Docker Compose, GitHub Actions (Matrix Builds, Parallel Runners), Azure Pipelines, Git,
CI/CD Quality Gates.
Linux & Web Servers: Linux Administration (Ubuntu, CentOS), Bash/Shell Scripting, Nginx (Reverse Proxy, SSL/TLS Termination
via Let's Encrypt), UFW Firewall, Systemd, SSH Hardening.
Monitoring & Databases: Prometheus, Grafana, PostgreSQL, Oracle Database (sqlplus, SQL maintenance scripts), Log
Rotation & Disk Auditing.
Test Infrastructure & Automation (SDET): Playwright, TypeScript, Python, Selenium WebDriver, Tricentis Tosca (SAP ERP),
Postman, Newman.
PROFESSIONAL EXPERIENCE
Frozeneon (iGaming Sector) Sep 2025 – Present
DevOps Engineer & SDET (Platform & Test Infrastructure) Remote
Cloud Infrastructure & IaC (AWS & Terraform): Provisioned and maintained isolated cloud testing and staging environments
on AWS using Terraform, automating 25+ cloud resources including VPCs, subnets, EC2 instances, S3 buckets, and security
group firewall rules.
Server Automation & Configuration (Ansible & Nginx): Authored modular Ansible playbooks to automate initial Ubuntu
server configuration, install Docker dependencies, and deploy Nginx as a reverse proxy with automated Let's Encrypt SSL/TLS
certificates and strict UFW firewall policies.
Containerization & CI/CD Optimization: Containerized application components and test harnesses using Docker and Docker
Compose; configured parallel test execution in GitHub Actions across 4 matrix runners, slashing execution time by 65% (from
3.5 hours to under 25 minutes).
Monitoring & Health Tracking: Deployed Prometheus and Grafana to monitor host health (CPU, memory, disk usage) and
track test runner performance, ensuring 99.9% uptime across staging servers.
Test Infrastructure: Maintained Playwright (TypeScript) automated test suites integrated directly into CI pull-request checks,
establishing blocking quality gates before release deployments.
