Hi there, I'm Jonathan Cardenas 👋

Senior Backend Engineer | Cloud & Infrastructure Specialist

I'm a software engineer with over 6 years of experience, specializing in the intersection of high-performance backend systems, cloud-native infrastructure, and data-driven applications.

My passion is building and scaling complex systems from the ground up. I don't just write the code; I design, deploy, and optimize the entire infrastructure it runs on, from Kubernetes clusters (EKS/AKS) to automated CI/CD pipelines.

  • 🚀 I lead backend development in Node.js (NestJS) and Python (FastAPI).

  • ☁️ I manage cloud infrastructure using Kubernetes, AWS (EKS, Karpenter), Azure, and Terraform.

  • 💸 I have extensive experience building monetization systems with Stripe, PayPal, and Mercado Pago.

  • ⛓️ I've developed smart contracts and token economies using Rust on the NEAR blockchain.

  • 🏆 Most recently, my team and I won 1st Place at the NASA Space Apps Challenge 2025 for AstraScope, an AI-powered exoplanet classifier we built with FastAPI, XGBoost, and React.
