Vinícius Mello Email and Phone Number

Umbler is a web hosting and internet services company that seeks to become number one in Latin America. I work on the product team, building solutions that add value and help the company achieve its goals.Among the activities I perform are creating monitoring with Prometheus, Automating tasks with Ansible/AWX, developing applications to perform scheduled tasks and analyzing and correcting performance problems in the environment.Among the projects I've participated, the one I'm most proud of is the creation of the backup automation system using Restic, where backups are stored in an Object Storage. In addition to the aforementioned challenges, there was the creation of a GoLang application for handling digital certificates generated by Let's Encrypt.One of our responsibilities, also because it is a scalable environment and accessed by several customers in all countries, is security. We apply Infrastructure as Code (IaC) concepts to maintain networking and firewall across all servers, with Kernel updates as new exploits are discovered.The Clients environment was in Docker Swarm and we are currently abandoning this orchestrator to migrate to Kubernetes (RKE 2) highlighting our interest in keeping the environment secure. Among the Web server technologies in these environments, the customer can opt for Apache or NGINX and MySQL or MariaDB databases. We are responsible for supporting all these environments.As for the SRE, I worked on both the Hosting team and the Email team, and each of them uses a different approach. This allowed me to gain experience both with the Consul environment that is consumed by Prometheus and given us visibility through Grafana. And also using ELK Stack from Elastic.One of the things I love about being a part of this team is the lateral knowledge that flows among the team members. Everything is available in repositories on GitHub and we review each other's code, seeking to achieve the best results and also become better developers.

Frimesa is an industrial food cooperative that has its own technology team that works from application development to user support. Including two local Datacenters, in addition to cloud infrastructures.I was working with the operations team as an IT Infrastructure Analyst, where I was responsible for making performance improvements, data security and environment monitoring. I was also responsible along with the team to architect the network infrastructure that underwent several improvements during the time I was there, such as migration from MikroTik Firewall to WAF Firewall with FortiGate and HP Aruba.I worked supporting virtualization and containerization of the environment, creating scripts to automate tasks, consuming APIs from the company's ERP Oracle E-Business Suite and also from Active Directory. I also managed the company's cloud environment, which at the time was Oracle Cloud and Azure.Due to the use of Oracle EBS as the company's ERP, almost all of our systems used an Oracle database. During my time there, I was able to participate in a version migration from Oracle Database 12c to 19c, in addition to, of course, gaining experience using it. In addition to ERP, another system that uses Oracle Database that I operated for a long time was the human resources management system, Senior and Senior X.Most of the systems developed internally were made in Java, which also allowed me to gain experience with Web servers such as JBoss/WildFly and the few systems that were not developed in Java, were made in PHP and hosted on Apache web servers.

Due to the new needs of the company and the growth of the team, my internship ended up being canceled so that Frimesa could hire me full time. In this new stage, I was able to start getting involved in the support and creation of services and servers to speed up the employees' production processes.Among the tasks carried out during this period, I can highlight the creation of the new Zimbra email system and the beginnings of creating VPNs between the headquarters and the branches, still very simple using MikroTik and PPTP. It was also the period in which I led the migration of the Antivirus system, abandoning Trend Micro and adopting Kaspersky on servers and hypervisors.

In my first paid job in the IT area, I started with an internship in the Server Infrastructure and Support sector at Frimesa. My responsibilities were simple and involved keeping the fleet of machines and computers operational and healthy, performing maintenance and formatting when it would be relocated.It also involved me being trained in computer networking, at the time using MikroTik Firewall and HP switches.

In my university internship, a colleague and I performed a 3D modeling of the physical structure of the university campus in a three-dimensional application using Blender. The application was developed using the Unity3D graphics engine and coded in C# and JavaScript. All code was versioned in Git repositories on the BitBucket platform and approved by the Internship supervisor.
