About Me

background expertis
background expertis

My passion for technology began in technical high school, where I first discovered the potential of programming. Since then, I have evolved through various languages and technical challenges. While my career was built on high-level software development, my current focus is on systems engineering and low-level development within Web3 ecosystems, where efficiency and performance are the top priorities.

In recent years, besides working as a Fullstack Developer on large-scale platforms with hundreds of thousands of monthly users, I have stood out for my ability to integrate emerging technologies into the workflow. I have mastered the strategic use of AI throughout the development lifecycle, skillfully orchestrating multiple agents when required to optimize results. As a Web Development Teacher, I strengthened my ability to communicate complex ideas clearly and effectively, which has helped me lead teams. I firmly believe that success is not just about the final product, but about effective collaboration and constant team growth.

Currently, my focus is on specializing in Rust for building robust, high-performance systems, applying it to both the Web3 ecosystem and scalable backend solutions. Although I possess expert command of Next.js and TypeScript, my professional goal is to evolve toward challenges where the security and efficiency of Rust take center stage. I am looking to join global teams to develop infrastructure solutions or high-demand applications, contributing my experience in scalability and my passion for efficient code.
