Managing thirty eight employees, among them, fourteen are related about twoprojects, which their report directly to myself: PInSIs (pinsis.c3sl.ufpr.br/) andSIMMCTIC (simmctic.c3sl.ufpr.br/). I am responsible to delegate tasks foreach member of those projects. To accomplish such a duty we explore sometechniques of Software Development, like Kanban. Another responsibility isextract the issues from the plan of work and materialize as a software. Fill upreports about all the tasks that has been developed, conduct meetings, eitherwith employees or customer. Revising thirty part code, managing via (git).

Customization of a Ubuntu/Linux distribution, to deliver to thousands of highschools all over Brazil. Customization not only on theme, but also in sometools and developed in python a control panel, to offer a friendly interface forschools environment. On this panel the user has access to a tool that allowsthe professor account to control all the computer on the same network, broad-cast actions for all/single computer, all from a single computer/application.Volatile environment for students, so it’s proof of destruction of student’s homefolder, among other functionalities (project repository: gitlab.c3sl.ufpr.br/le6.Architect/Implemented a set of scripts to generate a custom iso for installationgitlab.c3sl.ufpr.br/le6/create-iso.git.

Architect and implemented a platform of remote boot totally via Internet(HTTP), which the hard disk could be useless. This platform provides an en-vironment that each user can manage their own operation system images viabrowser, for any kind of maintenance. This project allowed me to be in touchwith several layers of development (DevOps), such as: modification in the ker-nel module DNBD3 gitlab.c3sl.ufpr.br/cdn/dnbd3, database MySQL, frontendPHP, task manager (Java), customization of the initramfs (file system for boot-strap an operation system) git.kernel.org/pub/scm/boot/dracut/dracut.git/ .This FS provides the environment to build the root system (in RAM),so any user in the earth with Internet, and the mechanism of iPXEon hand, can consume it. Repository with source code to generatesuch a FS: gitlab.c3sl.ufpr.br/cdn/initramfs-dracut-fw. Project web pageslxboxdev.c3sl.ufpr.br. The figure 1 shows an operation system booted inthe platform.

Begin of the partnership of the project OpenSLX, Brazil and Germany. Thisprofessional experience improved my abilities to work with different teams.Into my duties was the communication and development with both sides. Ideveloped personal abilities to manage staff and third part code. Plus thelocal culture.

Management and migration of servers. Development of web templatesand interfaces. Management of SQL and NoSQL databases. Managedmore than 500 points of work, hundreds of students account via LDAP.Installation/Setup of DNS, DHCP, TFTP, HTTP, LDAP/Kerberos services,remote boot via PXE/iPXE. Managed more than 80 virtual machines usingQemu and OpenNebula. Creation of VPN’s. Setup switches Summit X430Series, Pica8, D-Link. VLAN’s.Among the duties as Linux Admin, it has been accomplished the automationwith the following codes:(i) Python script for integration of LDAP and kerberos.(ii) Bash script to detect different architectures for remote booting.(iii) Architect/Implemented “Internet” infrastructure in the laboratory atUFPR, for the purpose of network security classes. The idea is to mimicthe behavior of Internet, implementing services, such as: DNS, DHCP,HTTP(S) and other services useful for the class. Such a network hasbeen implemented by VLANs, within unique switch (Pica8). Given animpression that each island of computers belongs to a segment in theInternet. Each, island has got its own network traffic exchange, gate-way, and each computer at each island must go through to this gateway,through gateway of the laboratory to reach the Internet.
