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 |
|---|---|
| Blackrack Labs (this site) | Public, sanitized documentation of the AI agent platform |
| agent-dev-kit | MIT-licensed multi-runtime agent development kit for OpenAI Codex, Claude Code, Pi, and OpenCode: layered architecture (communication, planning, capabilities, verification, safety), adversarial PR review, prompt-injection defenses, browser QA, provenance, and planted-bug evaluations |
| devpipe.net | Personal portfolio and self-hosted lab: Raspberry Pi, Proxmox, Docker, Traefik, Tailscale, and a full self-hosted app suite |
