Hi, I'm Sergio Ballestero 👋 · @lickybuay

Full-Stack Engineer with a design-systems background, working remotely with US product teams as an independent contractor from Paraguay (UTC-3). I build production SaaS end to end — React/Next.js on the front, Node.js/NestJS and Python/FastAPI on the back, PostgreSQL underneath.

  • 🚀 Building Welcomy — a multi-tenant queue-management SaaS (NestJS · Next.js · PostgreSQL), taken solo from an empty repo to production
  • 🧩 Author of TypeLang — an open-source macOS translator (Tauri + React) with bring-your-own-key across Claude, OpenAI, Gemini and local models
  • 🌱 Going deeper on practical LLM integration and self-hosted infra (Docker · Coolify · Traefik · Cloudflare)
  • 💞️ Open to collaborating on web & software development
  • 👨‍👩‍👧 Outside the editor: my family
  • 📫 Reach me at lickybuay@gmail.com

Stack: TypeScript · React · Next.js · Node.js · NestJS · Python · FastAPI · PostgreSQL · Docker
