Building high-leverage tools, resilient IoT automation, and AI systems.
I'm Vanhci. Focused on engineering local-first web utilities, reproducible agent automation, and robust local infrastructure that solves practical problems without friction.
Featured Artifacts
ToolKit Pro
A private, zero-installation web toolkit executing completely inside the browser. Includes in-memory multi-file Excel deduplication, splitting, and client-side image transformation pipelines.
Hermes Agent Skills
Curated automation recipes for AI agents. Production-tested procedures for multi-brand smart home orchestration, isolated network routing, and automated terminal debugging.
Core Principles
Local Computation
Process data directly on edge devices and in-memory. Zero unnecessary tracking and zero external data leaks.
No Single Point of Failure
Decouple services through failover tunnels and self-healing daemon layers that operate consistently even offline.
Automated Output
Use deterministic verification to back agent workflows, turning complex multi-step pipelines into reliable single actions.
