Hi 👋, I'm Mariano Echavarria

Senior Software Engineer · Backend & Cloud Systems · Remote · from Argentina 🇦🇷

mhechavarria

Electronic Engineer turned software engineer with ~10 years building backend systems and cloud-native applications across distributed international teams. My arc: Embedded (C/C++) → Backend (Node.js · Java) → Cloud-native (AWS · GCP) → AI-augmented Engineering — from writing IoT firmware to owning cloud platform infrastructure across 12 production regions, including FedRAMP GovCloud.

  • 🔭 I'm currently working on AI-powered bug triage — a Claude/Bedrock GitHub Actions workflow that cut triage time 73% at 100% accuracy (read-only triage + approval-gated implementation)

  • 🌱 I'm currently deepening LLM agent design, prompt engineering & cloud-native platform reliability

  • 👯 I'm looking to collaborate on open-source backend & cloud tooling — see Career OS

  • ⚡ Fun fact I'm an Electronic Engineer who designed PCBs and wrote IoT firmware before going all-in on cloud software
