🔅 Miratech delivers cutting-edge cloud computing technology consulting services to businesses worldwide.🔹 For what was I hired?* Google Cloud: Deploying architectures with Terraform, ensuring scalable and resilient cloud environments.* Pipeline: Developing robust CI/CD pipelines using GitHub Actions and Codefresh.* Scripting: Utilizing Python and Shell (Bash) scripting skills for automation and integration, optimizing processes and solving complex challenges.* Kubernetes & Helm: Managing and deploying Kubernetes manifests on Google Kubernetes Engine (GKE), and developing Helm charts to simplify and standardize application deployments.* AWS Solutions Architect: Designing and implementing scalable AWS architectures that align with business goals and industry best practices through AWS CloudFormation and CDK (TypeScript).* Go Application Development: Building command-line applications using Go.🔹 Achievements:* I tackled the challenge of migrating our Kubernetes manifests to Helm templates, successfully transitioning all our microservices and reducing the codebase by over 50%.* I successfully the migration of our pipeline code from Codefresh to GitHub Actions. This transition resulted in substantial cost savings each month and allowed us to streamline our code with increased dynamic functionality, leveraging both private actions and those available in the marketplace.* We encountered a challenge where deleting stacks in AWS was consuming significant team time. I was tasked with designing an AWS architecture and developing a Go CLI application to send information to an SQS FIFO queue. This queue triggers a Lambda function to delete stacks in the correct order. By automating this manual process with AWS CDK in TypeScript, I successfully streamlined operations, allowing our team to redirect their focus to other critical aspects of our projects.

🔅 Wiser Educação is an EdTech that provide some online services that have more than 300,000 users around the world.🔹 For what was I hired?* I developed CI/CD (Continuous Integration and Continuous Delivery) pipelines using Docker, shell-script (Bash), and Bitbucket to deploy services on Google Cloud Platform (GCP).* I developed APIs using Flask in Python and created automations to make processes more flexible and faster (e.g., creating and replacing expiring SSL certificates).* I worked with AWS services like S3 and Route 53.* I worked with GCP services like Cloud Run, GKE, Kubernetes Engine (GKE), Cloud Storage, Logging, and Monitoring.🔹 Achievements:I had a situation were the company had portfolio of around seven SaaS products, which frequently experienced outages due to the use of Let's Encrypt for free SSL certificates with a 90-day expiration period, and we didn’t have notifications for these expiration dates at that moment.To address this, I developed a Python application to automate SSL certificate renewal. The app monitored the certificates and initiated a replacement process one week before expiration, acquiring new SSLs from Let's Encrypt and updating them as Kubernetes Secrets. In case of failure, the app sent alerts to the DevOps team via email. Additionally, the application’s logs were sent to Cloud Logs in GCP for analysis.This solution ensured that SSL certificate expirations no longer led to service outages.

🔅 SEG Tecnologia builds and maintains data centers as long as large TCP/IP networks and develops web software (PABX IP) that manages IP phone communication based on Asterisk.🔹 For what was I hired?* I administrated over 80 Linux servers simultaneously , using Ansible, Puppet to manage tasks across multiple servers. I developed Bash and Python scripts for various purposes, such as handling backups and configuring networks (OpenVPN). I used Linux distributions like Debian, Ubuntu, and CentOS.* For monitoring, I installed and configured Zabbix to monitor hosts and services via SNMP, Zabbix agent, and Python scripts to send alerts through email and phone calls. I also installed, configured, and integrated Grafana with Zabbix and MySQL databases.* I managed versioning and maintenance of projects with Git, GitLab integrated with Jenkins to CI/CD process. Additionally, I maintained MySQL databases.🔹 Achievements:*At SEG Tecnologia, where I started in IT infrastructure and DevOps in 2017, I faced a significant challenge: building a monitoring system for an on-premise Data Center supporting a new telecom product. My task was to monitor every device in the data center, crucial for business clients, including hospitals. I set up virtual machines on Citrix Hypervisor, installed Zabbix and Grafana, and used Python to collect call metrics via SNMP. Additionally, I monitored storage systems, switches, routers, and Linux servers using ICMP and Zabbix Agent. I integrated Zabbix with Grafana to create NOC dashboards, tracking call volumes and infrastructure performance.* I addressed frequent telephone line outages affecting seven Emergency Medical Services across Brazil by enhancing Zabbix's alerting system. I developed a Python script to integrate with our Asterisk-based VoIP system, automatically placing phone calls and playing an MP3 file to notify on-call personnel of high-severity issues, reducing the risk of missed alerts.
