Agentic AI systems

Working with AI agents, not just chatbots.

This portfolio is built around practical agentic AI: tools that can take actions, inspect real files, coordinate tasks, remember procedures, and verify work instead of only generating text.

Core platform

Hermes Agent

Hands-on use of Hermes Agent as a local, tool-using AI assistant for project work: editing files, checking repositories, deploying sites, managing recurring jobs, and maintaining reusable skills.

Tool callingSkillsCron jobsVerification
Operating model

Human + agent workflows

Daniel uses agentic workflows to move from idea to artifact: define scope, update the board, edit the product, test locally, deploy, and confirm the public URL with real evidence.

KanbanAutomationCloudflareShipping
Applied agents

Nightly assistant bots

Recurring bots for home weather, precise rain alerts, technical AI news, and decision support — designed as practical agent workflows, not one-off demos.

Scheduled agentsDecision support
Knowledge systems

Memory + skills

Reusable procedures, project context, and operating rules are captured so future work becomes faster, more consistent, and easier to verify.

Procedural memoryDocumentation
Multi-step execution

From request to deployment

The site itself is proof: changes are scoped, edited, visually inspected, deployed, and checked on the live domain through an AI-assisted workflow.

Nightly automation bots

Two real assistants running as recurring systems.

These are not just portfolio ideas. They are practical nightly bots designed to deliver useful, specific information automatically — weather risk for home operations and technical AI awareness for professional growth.

Roof Weather Bot

A nightly weather assistant for the exact home area: when rain is expected, how much may fall by hour, hourly temperature, and precipitation probability. The public portfolio describes the system while keeping private coordinates off the page.
