PROFESSIONAL SUMMARY Infrastructure and Automation Engineer with a strong
foundation in Software Quality (Software Development Engineer in Test - SDET). Proven
expertise in designing scalable cloud architectures, containerizing applications, and building
zero-downtime CI/CD pipelines. Transitioned from a Senior AQA Team Lead - where I
managed a 19-person department-into a DevOps role, driven by a passion for Infrastructure
as Code (Terraform, Ansible) and Cloud environments (AWS). Highly skilled in bridging the
gap between development and operations by implementing comprehensive automation
(Playwright, Tricentis Tosca), robust monitoring, and secure, high-availability server
configurations for dynamic enterprise systems.

CORE TECHNICAL SKILLS

Infrastructure as Code.
● Containerization & CI/CD: Docker, Docker Compose, GitHub Actions, Azure
Pipelines.
● Web Servers & OS: Linux (Ubuntu), Nginx, Bash Scripting, SSL/TLS (Let's Encrypt),
UFW.
● Monitoring & Databases: Prometheus, Grafana, PostgreSQL, SQL.
● Automation Engineering (SDET): Playwright, TypeScript, Tricentis Tosca, Selenium
WebDriver.
● Tools & Management: Jira, Azure DevOps, Git, Postman.

PROFESSIONAL EXPERIENCE

Frozeneon (iGaming Sector) | DevOps Engineer & SDET | Sep 2025 - Present

● Cloud Infrastructure & Provisioning: Architected and deployed scalable staging
and testing environments on AWS (EC2, S3, VPC). Utilized Terraform for
infrastructure provisioning and Ansible for automated configuration management
(managed [X]+ resources/environments).
● Containerization & Networking: Containerized microservices and test
environments using Docker to eliminate environment inconsistencies. Configured
Nginx as a reverse proxy, enforcing secure HTTPS communication and implementing
strict firewall (UFW) rules.
● CI/CD Pipeline Architecture: Designed, optimized, and maintained continuous
integration and delivery pipelines, enabling parallel test execution (reducing test cycle
time by [X]%) and achieving zero-downtime deployments for high-load platforms with
99.9% uptime.
● Monitoring & Test Automation: Deployed a comprehensive monitoring stack
(Prometheus & Grafana) to track server health and CI/CD metrics. Concurrently
maintained a robust UI/API automation framework (Playwright, TypeScript) to ensure
rapid, shift-left quality gates.
MHP | Release Engineering & QA Tech Lead | Apr 2022 - Aug 2025

● Infrastructure Administration: Managed internal Linux (Ubuntu) testing servers.
Leveraged Docker Compose to provision isolated local environments, significantly
accelerating the workflow for a 19-person engineering and testing department.
● Pipeline Integration: Engineered continuous testing pipelines within Azure Pipelines
and GitHub Actions. Seamlessly integrated Tricentis Tosca and Selenium automated
suites into the build process to validate critical SAP Fiori and ERP workflows.
● System Scripting & Optimization: Authored custom Bash scripts to automate
routine Linux system maintenance, execute scheduled PostgreSQL/SQL database
backups, and manage log rotation.
● Team Leadership & Delivery: Built the release and QA workflow from the ground
up. Led integration testing and infrastructure delivery for the enterprise Transport
Management System (TFMS) in collaboration with SoftServe, ensuring stable data
flows between external SAP instances and corporate BI components.

Various Clients & Projects | Automation & Integration Consultant (Freelance) | Feb 2022 -
Nov 2023

● System Integrations: Validated REST API endpoints and complex system
integrations utilizing Postman, ensuring high availability and seamless data exchange
for E-commerce platforms.
● Database & Performance: Executed advanced SQL queries for database integrity
checks and delivered custom automation scripts that reduced manual operational
overhead by up to 40%.
● AI Systems Validation: Conducted specialized technical evaluations of AI-driven
applications, monitoring model accuracy, latency, and prompt response consistency.
