About Me

Get to know me better

Product-minded fullstack engineer

Senior Fullstack Product Engineer with 5+ years working with US startups, focused on 0→1 and 1→N products. I operate at the intersection of engineering, product, and data — owning problems end-to-end, from idea to production. Recently I led revenue-critical systems including dynamic pricing platforms and LLM-powered automation pipelines, impacting GMV and cutting operational overhead by up to ~70%. I also built and scaled real-time systems handling 1M+ interactions, with a strong focus on performance, reliability, and iteration speed.

My core strength is turning ambiguous problems into simple, scalable solutions — balancing speed and quality while keeping business outcomes front and center. Tech: TypeScript, Node.js, React, AWS, Kafka. Focus: product engineering, distributed systems, real-time data, LLMs. Open to high-impact remote opportunities globally.

Education: Bachelor of Computer Engineering, IF Sul de Minas (2017–2021), Poços de Caldas, MG. Languages: Portuguese (native), English (fluent), Japanese & Spanish (elementary).

Selected certifications: GoStack (Rocketseat), Data Structures & Algorithms (ZTM), Mastering System Design Interview (Sundog), Clean Code, Node.js, Generative AI fundamentals, Ignite Node, Dev with AI (Claude Code, Codex, Cursor).
