Luis Carrera

Software and artificial intelligence developer

Guatemala City. 14 years coding, self taught since the age of 15.

Profile

Software developer with 14 years of coding, self taught since the age of 15. Founder of Luic, where I lead the technical vision and its execution, and CTO of LabsChats. I build web applications with React, Next.js and Node.js, Shopify stores and WordPress sites, and I integrate artificial intelligence into operations that already run, using the Claude and OpenAI APIs, n8n and MCP. At B360 | Google Business View I raised WordPress load speed by 85% and cut Firebase costs by 45% by migrating the REST API to second generation Cloud Functions. Twelve projects in production, all of them open to check. I work from Guatemala City with clients in Guatemala, Mexico, Central America and the United States.
