I'm Emilio Hernandez Arellano. I turn mathematical models into systems that ship — closing the gap between explainable AI research and production systems that reach 160+ people every week, run day-to-day by a team of three.

Duality

One Engineer. Two Perspectives.

Academic Track

The Researcher

I focus on the "Why." I develop white-box analytical models for complex vision tasks, using evolutionary computation to recover hidden structural information from suboptimal environments — a transparent alternative to opaque deep learning.

Industry Track

The Builder

I focus on the "How." Same discipline as formulating the fitness function for a genetic algorithm: I don't write every line by hand, I define the problem — architecture, constraints, review criteria — precisely enough that directing AI agents to execute it produces the right system. The result: backend architecture, data pipelines, and transparent decision engines that handle real revenue and retain real people.

AI Systems Architect & Automation Consultant

Swiss Just · Remote

  • Evolved a consultant management system through four architectural stages: local Excel/SQLite scripts → cloud ETL → REST API → full-stack web app, designing every architectural decision end-to-end.
  • Migrated SQLite to Supabase (PostgreSQL), designing RLS policies and concurrent Python ETL scripts for automated weekly ingestion of sales and hierarchy data.
  • Rebuilt the backend from Flask to FastAPI with async endpoints, JWT auth middleware, and clean service-layer architecture.
  • Designed and directed the AI-assisted implementation of a Next.js + TypeScript frontend with role-based access control, auto-logout, and a private CRM with smart omni-field search.
  • Designed a transparent churn-risk engine with human-readable rule logic and admin-configurable thresholds — applying XAI principles so team leaders can audit every algorithmic decision.
  • Designed a real-time personalized messaging engine for 160+ consultants — admin-editable master templates stored in Supabase with dynamic variable interpolation and per-consultant overrides, replacing static batch generation with on-demand session-aware content.
  • Developed a greedy optimization algorithm for minimum-cost product combinations ensuring consultants reach required sales targets.
  • Conducted authorization testing on the web application to verify privilege escalation prevention — validating that non-admin users cannot access admin routes or sensitive data under any session state.
  • Deployed and hardened the production VPS end-to-end: Docker Compose services behind a Traefik reverse proxy, exposed only through a Cloudflare Tunnel — zero public ports — with dedicated non-root service users and fail2ban on top.
  • Directed a multi-agent AI workflow — Claude (Anthropic) as senior, Gemini as junior — reviewing outputs, making architectural decisions, and coordinating via structured handoff documents.

AI Trainer

Outlier · Remote

  • Evaluated multimodal content to determine whether images and audio were generated by AI systems.
  • Assessed artistic sketches to determine feasibility for realistic reconstruction using generative AI models.
  • Provided structured feedback contributing to improvements in frontier multimodal AI systems.
