Matheus Viana, frontend engineer in Joinville, Brazil.

Matheus Viana at his desk

Four years across many layers of software, end to end. Frontend, test automation, full stack, enough time in each to know how they actually fit together.

These days I mostly work on the financial modules of what we call TOTVS's supply logistics chain. I got to stand up a micro-frontend repository from scratch to ship a new product, and that is what I work on day to day. It started with the Cypress suite and the error reporting; with that foundation solid, my focus has moved to the architecture and the reasoning behind each call. The four roles that got me here, and what I actually owned in each, are on the experience page.

On my own time I design and ship my own products, from the first idea to a URL someone can use. They are on the projects page, written up with the parts that were actually hard.

Hackathons & events

Three years of showing up to build things on a deadline, in rooms full of people I had just met. Almost all of it through Senac, where I studied.

  1. Startup Weekend

    Startup Weekend

    Senac · one weekend

    One of my first times taking an idea into a room and defending it out loud. We did not place. Going and pitching anyway is what started to fix my communication, the part of the work I was worst at.

  2. JEDI Hackathon

    JEDI Hackathon

    11th edition · mid-2024

    My first hackathon. A team, a clock, and a stage I had not stood on before. Nothing about it came out polished, but it is the reason every hackathon after this one felt normal.

  3. Reuni Challenge 2024

    Reuni Challenge 2024

    2nd place

    Lages, Santa Catarina · one week

    My third hackathon, run through Senac. A week of discovery, a couple of pivots, and a lot of time in front of mentors who had actually built companies. We only locked the idea and built the kit in the last two days. What stuck: building is not the hard part. Getting a few of the right people to look at it and see something is. That is what makes a project click, and what makes anyone else care.

  4. ExpoInovação

    ExpoInovação

    2024 & 2025 · attended

    A regional technology fair I went to in 2024 and again in 2025. Nothing I competed in, just a room worth being in, to see what people around here are actually building.

  5. Senac Hub × TOTVS Hackathon

    Senac Hub × TOTVS Hackathon

    1st place

    Senac Hub Tecnologia · one week

    TOTVS sent engineers to mentor and brought real problems from inside the company, all around productivity. We built Epic.AI, a Jira integration that splits epics with a feedback loop, and I ran the pitch. First place. The lesson was not the build: a clear, direct pitch that leads with the value is worth as much as the work behind it. That changed how I approach everything since.

  6. Graduation

    Systems Analysis & Development · Senac · August 2025

    The degree the rest of this page ran alongside. Systems Analysis and Development at Senac Santa Catarina, the same place every hackathon and Startup Weekend above started from. 2023 to 2025.

    The thread running under everything above. Where I want to get to: being the technical reference between my team and the squad I work in, always adapting and leaving the environment more evolved than I found it.
