About me

Origin story

My journey in programming began at 16, during high school, when I won a scholarship at Fucapi. Being among the top 50 grades led to my first practical, paid experience: developing a school management system for the interior of Amazonas. This initial experience shaped my passion for using technology to solve real-world problems.

Current chapter

Today, I work as an AI Analyst and Full Stack Developer with just over 5 years of experience developing end-to-end applications. Currently, I work at Positivo Tecnologia, where my focus is on creating AI solutions, integrating intelligent models into efficient software architectures.

Technical expertise

Technically, my day-to-day involves Back-end development with Node.js and Python, while on the Front-end I use React and Next.js to build fluid interfaces with great usability. With Python, I build AI agents and automations that reduced operational costs and increased delivery accuracy — from LLM orchestration to intelligent task automation.

What drives me

My goal is to continue evolving at the intersection of Artificial Intelligence and Software Engineering, creating scalable, high-performance web applications that generate a direct impact on business efficiency and results.
