About

I am a senior software engineer with more than five years of experience, during which I have worked and gained knowledge in different branches such as backend, frontend, cloud computing, and distributed architectures. My technical expertise is mainly based on the JavaScript stack, specifically Node.js and React, and I have extensive AWS experience, especially with AWS Lambda. I have worked in different industries, primarily in startups with large workloads.

I have a track record of delivering tangible results, such as tooling to automate testing of microservices to reduce developers’ workload, identifying and solving problems, and proposing ideas to improve product performance. In recent years I have taken the initiative to lead the development of new functionalities and to lead teams, aiming to be involved in the entire SDLC phase of the product.
