MexicoWhat I'm looking for
I'm building a technical career through Python automation, Linux infrastructure, AI/data quality, QA, and IT operations.
As a freelance AI Trainer and Text Analyst at Outlier AI, I evaluated training data and model outputs for accuracy, relevance, consistency, and reasoning quality. I identified edge cases and delivered structured feedback to improve output reliability.
I built and operate the AfeLab homelab on Proxmox VE, deploying Linux containers, Jellyfin, SMB/NAS storage, SSH, and Tailscale remote access. I troubleshoot services, permissions, storage, sensors, and networking with recovery-oriented practices.
I've also built Python desktop and log-analysis tools, contributed QA and release-integrity work to an open-source automation project, and support Booking.com cases at TTEC through structured investigation and accurate documentation.
