Serasa Tech Summit Blumenau: helping others also means opening doors

A day for the community

On August 15, 2026, Serasa's office in Blumenau, in southern Brazil, opened its doors for the Serasa Tech Summit. The goal was simple and ambitious at the same time: to strengthen the region's tech community, making room for knowledge sharing, networking and new opportunities.

Serasa professionals took the stage as speakers and were available as mentors, and the event was supported by AWS, Datadog, MongoDB and GitLab.

I had the privilege of being a host of the event alongside Jefferson Machado, guiding the day, introducing each speaker and helping keep the energy and the conversations flowing from start to finish.

Blumenau, where it all began

This event means a lot to me. It was at tech companies in Blumenau that I started my career, writing backend code in Python, before moving on to the cloud and, later, to technical leadership. Much of what I learned came from people who shared what they knew without expecting anything in return.

One memory sums it up. I was just starting out professionally when I attended my first Python Brasil, the country's Python community conference. That is where I understood how people help each other in a community: a simple request for help was enough and, soon after, there were people sitting on the floor of the event's hallway, opening their laptops and coding together. Nobody asked about job titles or companies. Whoever knew, helped.

One request for help and, minutes later, people sitting on the hallway floor, coding together.

Helping build a space like this in the city where I started was a way of giving some of that back.

The same wish, two paths

That Python Brasil hallway never left my mind. In the article about amardoar, I wrote that I strongly believe in doing good to others, no matter who they are, without expecting anything in return. The Serasa Tech Summit is that same wish applied somewhere else.

At amardoar, helping means bringing people who want to donate closer to institutions that care for those in need. In the tech community, helping means giving knowledge, time and access: a talk that shortens someone's path, a mentoring session that unlocks a career, a conversation that turns into an opportunity. In both cases, the gesture is small for the giver and can be huge for the receiver.

As a technical leader, I see this every day: teams grow faster when knowledge flows, and a region's community grows the same way. A city with a strong tech community trains more people, attracts more companies and creates more opportunities, including for those who are still on the outside.

What stays with me

• Sharing multiplies. Whoever takes the stage learns as much as the audience, because explaining is the most honest test that you have understood.
• Community is built up close. Local events bring together people who live a few blocks apart and had never talked.
• Companies can be bridges. Opening the house to the community, with the support of partners, turns infrastructure into opportunity for a lot of people.

Next edition

There are already plans for the next edition of the Serasa Tech Summit, with no date set yet. To follow the news, follow my LinkedIn or Serasa's official LinkedIn.

Thanks to everyone who attended, spoke, mentored and helped organize, to Jefferson for the partnership on stage, and to our partners AWS, Datadog, MongoDB and GitLab.
