About Ricardo

I help startups, SaaS companies, and engineering teams build reliable backend systems, scalable APIs, cloud-native services, and automation pipelines using Python, Django, FastAPI, AWS, Docker, and CI/CD.

With 14+ years of experience in Python backend development, I can join complex projects quickly, understand existing systems, and deliver production-ready solutions without requiring heavy supervision. My work usually focuses on backend architecture, REST APIs, third-party integrations, data pipelines, internal tools, deployment workflows, cloud infrastructure, and performance improvements.

What makes me different is that I bring both hands-on engineering and strong ownership. I do not just write code; I help clarify requirements, identify risks, improve maintainability, and make technical decisions that support the business. I have worked on healthcare platforms, education systems, deployment automation, AWS-based services, metrics dashboards, and backend modernization projects.

Typical projects I can help with include:

Python backend development with Django or FastAPI
REST API design and implementation
AWS cloud services and serverless architecture
Docker-based environments and CI/CD pipelines
Database modeling with PostgreSQL, MySQL, or MongoDB
Backend integrations with external APIs
Data processing, ETL jobs, and automation scripts
Performance optimization and legacy system modernization
Internal tools and operational dashboards

I am a good fit for teams that need a senior backend engineer who can communicate clearly, work independently, and deliver clean, maintainable, production-ready code.
