About

Felipe Tejada Padilla

AI Native Software Engineer · Agentic Development Systems · Backend, Cloud & Developer Productivity

Colombia · Open to remote AI Platform / Backend roles worldwide.

I am an AI-native software engineer with 5+ years building production backend systems, AWS infrastructure, data workflows, and AI-assisted engineering systems. I build reliable software — and the systems that make AI-assisted development repeatable, safe, and measurable.

Blackrack Labs is my live platform lab: the infrastructure behind this site runs agents for real users around the clock, and it is the most honest portfolio I can offer — working systems, not screenshots.

Public projects

Project What it is
