Hello, I am

About Me
At work, my focus is the back end: APIs and microservices in Node.js and TypeScript, with an eye on performance and stability. In freelance projects, I bring that same care to the front end, building Next.js interfaces that blend performance and aesthetics.
My Journey
I started my journey in 2021 as a Full Stack JavaScript Developer, building complete web applications across both front end and back end. Since then, I've been deepening my skills and staying aligned with the latest trends in modern web development.
Today at Squid Creators, I work mostly on the back end, on the platform's Node.js and TypeScript microservices. I've taken a product from proof of concept to production and cut an 11,000-profile import from almost 8 minutes to under 1. I also built AI-powered video review, which cut the time until a creator knows what to fix from 22 hours to 19 seconds.

It means I don't stop at the code: I understand the problem before writing the solution, measure before optimizing and follow the work until it runs well in production, whether it's a microservice or an interface.

Squid Creators
Full Stack Developer
Building and maintaining the Node.js + TypeScript microservices behind a leading influencer marketing platform: REST APIs, background workers and ETL jobs, with a focus on stability and performance. Also responsible for the team's first-line bug triage: taking issues from support, making sure each ticket is clear, understanding the problem and assigning the fix to the right person, which keeps fixes fast and high-quality.
RPG Project (Volunteer)
Team Lead
Led a small, junior team that was still finding its footing, building a platform to connect RPG players. The challenge was keeping the project moving while the team gained experience: I organized the backlog, refined tasks so they were clear and reviewed code to keep quality up.
Trier Sistemas
Support and BI Development Analyst
Started in support, serving pharmacies and manually recovering the data that fed the BI platform whenever the automatic collection failed. After showing interest in development, I was promoted and started building the Qlik Sense dashboards clients used.
