Hi, I'm Guillermo (Willy) Cifre 👋

Software Engineer with 3+ years building production systems in TypeScript and Node.js. Currently expanding into Platform Engineering and systems programming with Go, while building developer tools and automation infrastructure.

🚀 What I'm Building

I focus on backend services, developer tools, and infrastructure automation. Currently working on:

  • env-manager-cli (Go) - CLI tool for managing environment variables with PostgreSQL backend
  • Production deployment automation - Bash scripts + AWS Systems Manager for multi-client deployments
  • Developer experience - Building tools that solve real team collaboration problems

💻 Tech Stack

Backend:

  • TypeScript, Node.js, Express.js (3+ years production)
  • REST APIs, GraphQL, MongoDB optimization
  • Go (building CLI tools and learning systems programming)

Databases:
