╚══════════════════════════════════════════════════════════╝
I build things that have to actually work — distributed systems, event-driven pipelines, AI-integrated platforms, and P2P protocols. My stack goes deep on .NET 8/9/10 and Rust, and wide across the full product lifecycle: architecture, backend, cloud infra, mobile, and everything in between.
3+ years of professional experience across enterprise integration systems, real-time data pipelines, cross-platform mobile apps, and greenfield product builds. I contribute to open source (actix ecosystem 🦀) and care about doing the craft well — clean APIs, proper test coverage, systems that survive the weekend.
Currently finishing a CS Engineering degree at UDLAP (GPA 4.0) and shipping software in parallel.
Not a magical girl — just a software developer who takes the borrow checker personally.

🗂️ CacheServer Rust
Custom cache server implementation in Rust — fast, correct, and built to understand the internals.
$ gh pr list --org actix --author dontloseyourheadsuActive contributor to the actix ecosystem — one of Rust's fastest and most widely deployed async web frameworks. If you're building high-performance Rust web services, you're probably running code the community has touched together.
