About this gig

I design and build scalable, production-ready backend and full stack systems for startups and growing companies. With experience as a Senior Backend Engineer at Rappi and a strong fintech background, I specialize in creating robust architectures that handle high traffic, complex integrations, and real-world business challenges.


I can help you with microservices architecture, API development, fintech and payment integrations, cloud backend systems, and scalable web or mobile platforms. I collaborate with international teams and follow best practices to deliver secure, maintainable, and high-performance solutions.


Whether you need to build a system from scratch, scale an existing platform, or integrate with third-party services such as banks, payment providers, or internal enterprise tools, I provide clear technical direction and reliable execution.
