- Implemented Merge request standards, delivering Infrastructure as Code (IAC) solutions within tight deadlines. - Worked on Kubernetes-based application deployment using Helm charts and manifests through Terraform deployments. - Heavily utilized Terraform and Terragrunt for infrastructure management, establishing a dependency structure based on Terragrunt. - Collaborated closely with clients, providing training on IAC and AWS infrastructure. - Code maintenance in GitLab for streamlined collaboration and version control according to gitlab best practices.

- Managing user access and permissions for AWS resources using AWS IAM (Identity and Access Management). Creating, modifying, and deleting IAM policies and roles to ensure security standards are met. Providing guidance on IAM-related issues and collaborating with teams across the organization to implement and maintain IAM policies and best practices. - Collaborate with the solutions architect teams to evaluate new or existing AWS services requested by Aegon's business units and determine the best approach for implementing them. - Possess a strong understanding of AWS services on the API and SDK level, ensuring successful deployment of these services. - Optimize security, cost, and maintainability of the infrastructure design to align with company standards and AWS best practices. - Troubleshoot and resolve issues related to the AWS infrastructure, including access control, permissions and application deployment. - Implement and maintain AWS Service Control Policies on the organization level. - Utilizing orchestration tools such as Atlantis with Terraform and AWS Step Functions to automate and streamline workflows, ensuring efficient delivery of services and applications. - Providing on-call coverage for the organization, addressing any AWS-related issues or incidents that arise in a timely and efficient manner to minimize downtime and ensure the smooth operation of services and applications. - Utilizing a strong understanding of the Python programming language and PEP8 standards to create reusable, maintainable, and efficient code. - Utilizing expertise in Terraform to develop and maintain infrastructure as code, including the creation and modification of Terraform modules, templates, and scripts. Ensuring that Terraform code is efficient, modular, and follows industry best practices, while also collaborating with other teams to implement changes and ensure consistency across the organization's infrastructure.

- Created and maintained documentation for scripts, processes, and procedures to improve overall team efficiency. - Worked with the team to automate infrastructure tasks using various scripting languages and DevOps tools. - Participated in architectural discussions to identify areas of improvement in security, cost, and maintainability. - Utilized Github for version control, code reviews, and peer reviews to ensure compliance with best practices and standards. - Continuously updated skills and knowledge of AWS services, DevOps tools, and programming languages. - Developed skills in working in an Agile team, utilizing Jira, Sprints, and Kanban boards to manage projects and collaborate with team members.

I worked closely with customers to troubleshoot fundamental authentication-related issues, virtual machines, Citrix environments, VPN-related problems, mainframes, and business-critical applications. I utilized the BMC Remedy with SmartIT system as the primary ticketing platform. This allowed me to track customer inquiries and issues effectively and efficiently.

- Decoupled the application into microservices, and migrated server-based applications to serverless. - Built a CICD pipeline using codepipeline and codebuild jobs, and separated it into multiple environments (staging, dev, production). - Implemented version control for all code in GitHub, enabling developers to work separately and integrate their code continuously into the production environment without interfering with each other. - Maintained the CICD pipeline and developed new features as required. - Implemented monitoring with cloudwatch and notifications to slack to ensure everyone is aware of deployment issues. - Implemented approval flows on GitHub to ensure secure code changes in staging and production. - Implemented backup on a schedule and restore to RDS, Dynamodb and Cognito User Pools by using AWS lambda functions in Python. - Played an active role in facilitating collaborative brainstorming sessions with the owner to evaluate and refine the architectural design of both the application and infrastructure. - Ensured the infrastructure is aligned with the developers' needs, providing seamless support for the development, deployment, and maintenance of applications - Migrated and automated all the manual deployments to IAC by using Terraform, Bash, Python, Docker and AWS services.

- Provided technical expertise and guidance to the team on AWS infrastructure, services, and technologies. - Ensured compliance with security policies, procedures, and regulations, identifying and addressing potential security risks and vulnerabilities. - Actively participated in architectural reviews to identify areas of improvement in the existing AWS infrastructure. - Collaborated with the internal team to design and implement innovative solutions that aligned with the company's standards and AWS best practices.

- As an Information Technology Support Analyst at MODIS, I provided Level 1 technical support for IBM, specifically serving the Mercedes-Benz company in Hungary. I was responsible for assisting with a wide range of technical issues related to IT systems, ensuring smooth operations and quick resolution of technical problems.
