Working in Digital Systems Design for the last 4 years: I've written RTL for server-class RISC-V SoC components, built an Image Signal Processor pipeline that runs on FPGA, and contributed to an actual chip tape-out on SkyWater's 130nm process. I've taken designs through the full life cycle — specification, simulation, FPGA prototyping, fabrication, and silicon bring-up in the lab, where I wrote C and assembly tests to validate real hardware. Alongside design work, I also write technical articles on chip design, RISC-V, and embedded systems — so if you need documentation or engineering content that's accurate and readable, I can help with that too. Feel free to reach out or send an invitation to get started.

Computer Science undergraduate at the Federal University of Espírito Santo (UFES). Mainly interested in Theory of Computation, Algorithms, Compilers, Distributed Algorithms, and Cryptography. Currently working as a research assistant in cryptography, specifically on zero-knowledge proofs. My work turns on two axes: computing and mathematics. I’ve spent years building a firm base in both. I grew up between Brazil and the United States, speaking Portuguese and English as first languages. I now study Computer Science at the Federal University of Espírito Santo (UFES), on track to graduate in December 2026.
