Who am I?

Hello!
My name is Jurandi. I enjoy doing exercises, practicing sports, and I love animals, all of them. I own a small farmhouse, have children, and a wonderful wife. I am an analyst and Product Owner, and I love what I do. I have developed various games and systems, and I was part of the development teams at the Federal Senate and the Central Bank of Brazil.

I conduct a comprehensive analysis of the business and system, considering the end-to-end product. Requirements gathering, documentation, pricing, estimates, and timelines, combined with well-defined sprints aligned with the team. I monitor the system's performance through continuous analysis and validations. I understand needs and requirements in an agile format, such as user stories or equivalents. I act as a facilitator in the system development process, paying special attention to refining the backlog. My experience includes hands-on experience with agile software development methods, and I am a proactive person focused on providing effective solutions.


Here you will find more information about my professional career.
I hope you enjoy it!

EDUCATION

Software Engineering

2021 UNICIV, Londrina PR, Brazil

Software Engineering with Emphasis on Quality and Software Testing.
In pursuit of professionalization and further enhancement of my capabilities to manage and develop quality software, understand processes throughout their cycles, I sought the necessary techniques and methodologies for effective and essential development. Among various knowledge areas, my specialization deeply covered:
Agile Methodologies Quality Software Business Intelligence Source Code Quality (Clean Code) Software Testing Leadership and People Management Strategic Business Communication Design Patterns Usability Engineering Configuration Management, Version Control, and Change Management Alternative Data Architecture and Models - NoSQL / Data Warehouse / Data Mining Analysis and Specification of Requirements Project Management with Scrum.

Systems Analysis and Development

2019 FAP, Patrocínio MG, Brazil

It's not enough to know a little about technology: as a systems analyst, I needed in-depth and complementary technical knowledge. I aimed to master different programming languages, understand operating systems (such as Linux or Windows), and hardware platforms. In addition to seeking broad knowledge in the field, I graduated as a more complete professional, capable of seeing the system as a whole, in an integrated manner.
Through hard work, dedication, and continuous study, I acquired and improved my skills, and today I can carry out a system project until it is delivered for use. Essentially, as an Analyst, I can:



  1. Perform maintenance on existing systems and repair them as necessary.
  2. Define the requirements and functionalities of a system to be developed.
  3. Develop, test, and implement systems based on the definition of requirements and resources.
  4. Develop system documentation. In the documentation, I can include tutorials, user manuals, maintenance routines, and standards for new versions.
  5. Provide customer support. With technical knowledge, as an analyst, I guide the user on how to use the system and also identify bugs based on customer complaints.
  6. Identify, map, and analyze technological options and tools in the market to be acquired by a company.
And the list continues...

Maintaining a Microsoft Windows Server 2003 Environment

2006 EFTI/Microsoft Inc.

Specialization in Networks.
Among others, I have several specializations in complementary knowledge. This one, in the creation and maintenance of servers and network environments, is something I believe is worth mentioning. Network knowledge goes beyond understanding protocols and anticipating possible invasions; it also helps in the development of complex systems that depend on intranets, VPNs, RDPs, and many other network-layered applications and their protocols, useful in a development environment.

2022 Personal Presentation Video

Here is a short 2-minute video introducing myself, not as a professional, and sharing three interesting facts about me.

Photography

Learning

I believe we will never know enough; by being open to learning, we gather more knowledge, and at some point, we become a source.
I keep my mind open to facilitate the influx of data, and in this way, I learn new languages, new cultures, new skills. That's how I learned everything I am today, including reading and writing in Hebrew, Greek, and a bit of Latin. Similarly, I learned other languages and everything else I use in my academic, professional, and personal life.

Creativity

Management

I have been an entrepreneur; I consider myself a visionary and am good at working in a team. I can receive and follow orders, but I can also manage a team, motivating people to achieve defined objectives, delivering the desired value.
Using Agile methodologies and maintaining focus, if necessary, changing focus is also an option.

Advetising

Resilience

Every choice should be resilient; indeed, when we seek the simplest, the choice is probably the right one.
In my life, I had to start over many times; over time, I learned that it is not possible to start over "from scratch." We always take our experiences with us to the next level, to the next place. When we start over, we carry our skills, experiences, and knowledge with us. So, yes, resilience is an important and necessary part of me.
