AI engineer · founder of TriHerm · technical educator
I build practical AI systems, agentic workflows, and full-stack software that turn fragmented business operations into reliable products.

I work at the intersection of AI engineering, software architecture, and business operations.
Through TriHerm, I design and implement systems for:
- lead capture, qualification, and follow-up;
- operational workflows and internal tools;
- company knowledge and AI-assisted retrieval;
- agentic workflows with permissions, approval gates, and human oversight;
- bilingual products for English- and Spanish-speaking teams.
My goal is not to add AI as another layer of complexity. It is to build systems that reduce manual work, improve visibility, and can operate reliably in production.
TriHerm — AI systems for real business operations
TriHerm turns disconnected workflows, tools, and information into working systems. Current work includes lead operations, workflow automation, internal knowledge systems, and custom AI implementations.
Fernando Abishai — technical analysis and education
I publish practical explainers and editorial analysis in Spanish about AI, software engineering, infrastructure, technology companies, and the systems changing business.
- Production AI systems: LLM workflows, retrieval, structured outputs, evaluation, observability, and human review.
- Agentic operations: agents that act under budgets, permissions, approval gates, and auditable policies.
- Operational software: systems for leads, internal processes, knowledge, and business visibility.
- Programmable payments: researching stablecoin rails, Base, and agent-to-service transactions for future business systems.
- Local-first creator tools: private, user-controlled software with optional AI instead of mandatory cloud dependence.
