At Instruct, as a senior software developer, i'm part of a team responsible for multiple projects that deal mainly with datacenter management automations. In these projects i had the opportunity to work and get more experience with external systems integrations, such as Commvault, Brocade Fabric OS, Juniper, VMware, GCP, AWS and others. I also had the opportunity to deal with a highly competent and cooperative team, which makes the experience of managing and mentoring other developers much more enjoyable and rewarding.Some important achievements i've accomplished so far at Instruct:- Helped my team to make automated datacenter operations, performed by our client analysts, much faster. Some operations used to require a few hours to be completed, and now it's done by the automation in no more than 20 minutes;- I helped my team design a new system, responsible for provisioning appliances on VMware, valuing simplicity, using as much as possible the base of technologies we already had consolidated, without making it difficult for other developers to learn and maintain;- I led the containerization and migration of a system maintained by external developers to our client's infrastructure, so that we could support the system without major friction;- Mentored developers with less experience, at trainee and junior levels, to help them reach a satisfactory level of skills so that they could also help the team to continue making improvements for our client.
