I have over 12 years of experience in software development, focusing on creating scalable, secure, and sustainable web applications. I work primarily with Ruby on Rails, PostgreSQL, Sidekiq, and Svelte, in addition to managing infrastructure on AWS (EC2, S3, RDS, CloudWatch).
I have solid experience in API architecture, integrations with external services, background jobs, deployment automation, and observability (monitoring and metrics). In my workflow, I prioritize automated testing (RSpec), rigorous code review, CI/CD (GitHub Actions and AWS pipelines), and best practices for versioning and security.
One of the most relevant projects was at Santander, where I modernized a legacy cash flow control system — originally in Microsoft Access — transforming it into an integrated, lightweight, and highly reliable web application. The project increased operational productivity and reduced failures in manual processes.
Currently, I am dedicated to backend engineering with Rails, focusing on scalability, automation, and system integration, always seeking to balance technical quality, delivery speed, and product impact.
Modernized a legacy Access system into a dynamic web application, integrating multiple operational systems into a unified platform.
Full-stack e-commerce solution with payment integration, inventory management, and admin dashboard.
Custom CRM solution with advanced analytics, customer tracking, and automated workflows.
I'm always open to discussing new projects, creative ideas, or opportunities to be part of your vision.
