Fernando Marques is a Senior Software Engineer from Brazil with six years of experience building impactful web and AI-driven systems, specializing in Ruby on Rails and React with a backend inclination. He has led high-stakes initiatives at fintech and edtech companies, improving AI document extraction precision by 200% and automating tutor-student matching to save millions annually. Comfortable running “war rooms,” mentoring engineers, and interviewing to raise hiring bar, he translates domain knowledge (investments, invoicing, integrations) into reliable production solutions. Fernando also designs developer productivity platforms—one of which saved his team tens of thousands monthly—and combines hands-on coding with product-facing discovery and documentation work. Quick to adopt and migrate ML tooling (e.g., moving models into SageMaker for 60% faster runs), he thrives on complex challenges that blend systems, data, and user impact.
