What I'm looking for

I seek a role that fosters innovation, encourages team collaboration, and offers opportunities for professional growth.

I'm Leandro Simões da Silva, a Software Engineer and Architect with a decade of experience in developing and architecting robust web and mobile applications. I hold a Master's degree in Computer Science from UFJF and have honed my skills in Javascript, Typescript, Node.js, React, and React Native. My expertise extends to designing scalable solutions using cloud infrastructures such as AWS and Docker, which has enabled me to lead teams effectively and drive innovation through solid architectural patterns like Clean Architecture, Domain-Driven Design (DDD), and Command Query Separation (CQS).

Throughout my career, I have delivered full-stack solutions that optimize performance and enhance user experiences across various industries, including e-commerce, fintech, and SaaS. My recent role as a Senior Software Engineer at EximiaCo involved instrumenting Node.js applications to improve observability for fintech clients, while my experience as a Bootcamp Instructor allowed me to teach programming to over 300 students, achieving a remarkable job placement rate. I am passionate about user-centric development and solving complex challenges, always striving to deliver impactful results.
