Steven Vallejo Ortiz

I am a Software Architect and Philosophy student at the University of Antioquia, with over 10 years working with technology and more than 8 years of professional experience in software development.

My specialty is the design of highly complex distributed systems and the integration of deterministic Artificial Intelligence: I combine RAG models, autonomous agents, and simulation engines (Agent-Based Modeling, ODEs) with formal logic layers to eliminate hallucinations and ensure predictable behavior in production.

Featured projects:

• Humanizar Systems: multi-tenant SaaS ecosystem with POS, DIAN electronic invoicing, and fintech.

• Finca Directa: transactional automation architecture with OCR, idempotency, and cloud classification.

• Critertec / Soy Digital (INDOTEL, Dominican Republic): frontend with offline support, synchronization, and data analysis tools.

• Agora: proprietary distributed AI platform (technical architecture test).

I work remotely from Medellín (GMT-5). Current availability: up to 10 hours per week for freelance projects.
