A little bit about me
Hi, I’m Federico León, most people just call me Fede.
I’m a Software Engineer, Software Architect and tech entrepreneur from Córdoba, Argentina. I’ve been building and scaling software since 2004, from low-level embedded systems to distributed cloud-native architectures used in production across the world.
I specialize in real-time, high-performance backend systems using Go and Java, with a strong focus on microservices, infrastructure, gRPC, Kubernetes, and DevOps. I’ve helped startups and companies move from fragile monoliths to robust, scalable architectures — and I’ve done it hands-on, not just on whiteboards.
What I Do
- I build systems — production-ready, maintainable and scalable.
- I teach technology — in a way that’s practical, honest, and based on real-world use cases.
- I help with teams — to solve architectural bottlenecks, implement CI/CD, migrate to the cloud and design services that actually work.
Whether you’re an individual learning your first backend service or a company struggling with service reliability and delivery speed — I can help.
Why Learn With Me?
I don’t teach theory in a vacuum. I teach what I do every day.
My goal is to make complex topics digestible and immediately useful — no fluff, no filler, no fake success stories.
I’ve spent the last two decades writing, debugging and shipping code under pressure. I know what breaks in production. I know what scales. And I’m here to pass that on.
Let’s Work Together
Looking to:
- Build a backend from scratch?
- Migrate your monolith to microservices?
- Implement gRPC and async processing?
- Scale your architecture or optimize delivery pipelines?
Let’s talk.
