• Projects implementation and management of infrastructure (staging, and production environments) and cloud services with a focus on AWS (VPC, NAT Gateway, VPC Peering, EC2, EBS, AMIs, ELB, S3, CloudFront, CloudWatch, X-Ray, IAM, CloudTrail, AWF, Route 53, RDS, Lambda, App Runner, ECR, Amplify, Organizations, Cost Explorer, Budgets, AWS Backup, AWS Compute Optimizer), in addition to others such as Azure and GCP. • Supporting developer teams • Implementing infrastructure as code using Terraform, standardizing and automating resource provisioning ensuring safer, replicable, and scalable environments. • Development and maintenance of CI/CD pipelines to automate testing, integration, and deployment of a variety of applications, optimizing the efficiency of the development and delivery process. • Automation of renewal of TLS(SSL) security certificates; • Implementation of scans in search of CVEs (Docker Scout) in container images, reinforcing the security posture of the solutions. • SonarQube implementation and integration with projects. • Workloads and databases migration. • Collaboration in the implementation of a Project Panel integrating AWS Cost Explorer, which allowed a unified view of cloud computing costs, facilitating financial control and FinOps practices. • Implementation of monitoring practices, ensuring high availability and performance of systems. • Implementation of the AWS Well-Architected Framework to ensure that our cloud architecture follows best practices for operational excellence, security, reliability, efficiency, and cost optimization. • Analysis and proposal for cost savings. • Multiple PoCs, play a fundamental role in experimenting and validating new technologies and approaches.

• Guidance for companies in migrating on-premise infrastructures to cloud solutions or transforming into hybrid environments, planning and executing strategies that maximize operational efficiency and scalability. • Implementation and management of infrastructure and cloud services. • Implementation and support of continuous cloud environments, ensuring high availability and optimized performance. • Assistance for companies in improving their processes using automation, resulting in more efficient operations and a reduction in manual errors and operational costs; • Workloads and databases migration. • Development and maintenance of pipelines. • Support operational environments, ensuring their stability and reliability through continuous monitoring and proactive maintenance. • Implementation of governance policies to effectively manage the use of cloud resources, including backup and risk mitigation routines. • Management of users and security groups. • Guidance on adaptations to LGPD (equivalent to GDPR), ensuring that companies' data practices comply with data protection regulations. • Implementation of network storage solutions (NAS), improving data management and accessibility.At this stage, I worked with several cloud providers such as AWS, GCP, Azure, Digital Ocean, Linode, and others.

• Customer service, troubleshooting, and continuous support throughout development times to facilitate operations without interruptions in deliveries. • Infrastructure deployment with Linux servers, adapting on-demand services in public and hybrid networks, including DNS (Bind), web server (Apache), email server (Exim, Courier), FTP (Proftp), and security (CSF, pfSense ). • Implementation and maintenance of Windows Server servers for specific applications, ensuring the operability and security of the systems. • Automation of the delivery, implementation, and maintenance process of pipelines. • Complete migration of our infrastructure from Windows to Linux-based sites, a strategic initiative that resulted in significant savings and increased system reliability. This project involved a detailed analysis of operational needs, specific planning, and meticulous execution, ensuring a smooth transition and minimizing the impact on daily operations. • Monitoring environments with solutions such as Nagios and Cacti. • Implement and maintain a wide range of services on Linux-based servers, including files (Samba), proxy (Squid), user control, and access policies. • Development of robust backup routines, ensuring the integrity and recovery of critical data for business continuity.

• Development of websites and applications using HTML, CSS, JavaScript, PHP, and SQL (MySQL, Firebird), creating and maintaining websites that meet specific customer needs. • High-quality customer service, resolving technical issues and assisting with our digital services. • Support for the developer team, facilitating the resolution of technical challenges and the implementation of features. • Develop and manage web projects, applying methodologies such as Scrum and Kanban to optimize our workflows. • Implementation and development together with the development team, an innovative application for task management integrating customer orders directly into our system. This solution allowed automation of communication, reducing face-to-face meetings and telephone calls, and a significant increase in team productivity. • Expertise in developing an effective project management system, ensuring project delivery within deadlines and with the quality expected by customers. • Developing and maintaining a comprehensive documentation base, including incident logs and supporting materials, to facilitate knowledge sharing and best practices within the team. • Adoption of agile practices, such as Scrum and Kanban, to improve collaboration and project delivery, improving team productivity and efficiency.

• Create and design websites, using technologies such as HTML, CSS, JavaScript, ASP, PHP, and MySQL. These skills allowed me to develop visually attractive and functionally robust websites. • Implementation of interactive animations in Flash with ActionScript, enriching the user experience and the visual presentation of projects. • Significant migration, moving from an environment based on Windows and IIS to an environment entirely based on Linux and Apache. This strategic change harmed our operational costs by reducing dependence on paid licenses and adopting free software-based solutions. • Design and active participation in the development of a comprehensive content portal, which has become a central point for regional news, events, and cinema, among other topics. This portal not only generated thousands of visits monthly but also served as a platform to offer advertisements as well as complementary services such as pre-designed websites, website hosting, and domain registration, which guaranteed an increase in revenue.
