CAREER PROFILE
I love designing solutions that streamline routines and boost productivity. As a Product Engineer and Full-Stack Developer, I work mainly with TypeScript, React, Node.js and Next.js, acting as a bridge between enterprise clients and engineering. I lead discovery meetings, gather strategic requirements, prioritize the backlog and write clear technical documentation that helps teams ship features with confidence. I recently completed two graduate certificates at UFPR: Applied Artificial Intelligence and Agile Software Development. In AI, I deepened my knowledge of Machine Learning, Deep Learning and Big Data tools, working with models such as neural networks, decision trees, XGBoost and Random Forest. In Agile, I strengthened my skills in collaboration, short delivery cycles, continuous improvement and DevOps-oriented practices. My journey spans diverse environments: from the Brazilian Army, where I learned discipline and teamwork, to volunteer experiences in Brazil and abroad, which expanded my worldview and empathy. These experiences reinforced my belief that technology is not just about writing code, but about creating solutions that positively impact people's lives. On every project, from UI/UX prototyping to implementing screens, APIs and AI-powered features, I keep the user at the center. I care about building scalable, accessible solutions that are aligned with real needs, not just technical elegance. Today I position myself as a Product Engineer and Full-Stack Developer specialized in Applied AI, focused on simplifying workflows, raising productivity and connecting business goals with robust, well-designed software.
