Building AI systems that turn information into decisions.

Founder working on AI tools for everyday life through Giiim and industrial intelligence systems in stealth.

My Interest

Building decision intelligence systems for life and industry

I build AI systems that turn information into decisions.

Through Giiim, I experiment with small AI tools for everyday life, from understanding food ingredients to comparing AI reasoning.

In parallel, I am building industrial intelligence systems in stealth for complex material, energy, and manufacturing decisions.

Across both paths, the focus is the same: designing systems that help people and industries make better decisions.

Currently building in public.

One thesis, two operating tracks.

Consumer tools and industrial systems both connect back to the same question: how does information become a better decision?

Giiim

AI tools for everyday decisions. Small experiments built fast, with a bias toward useful clarity over feature sprawl.

Tools
Paralyz
EatWell
MenuVision
BlueStockPrint
FitWell
NoSweat

Stealth Industrial Intelligence

Systems for materials, energy, and manufacturing decisions. Company and product names remain private while the work is in stealth.

Status
Stealth
Industrial AI
Decision Systems
Paralyz (Coming in 2026) AI reasoning comparison for information trust and choice clarity.
EatWell (Coming in 2026)< Ingredient and nutrition guidance for everyday food decisions.
MenuVision (Coming soon in March) Food exploration support for faster, more informed menu choices.
BlueStockPrint (Live) Decision support for long-term investing and market thinking.

Thought leadership around systems and decisions.

Writing is where the operating model becomes explicit: materials, AI, information, and the decisions they shape.

Matter that Matters

Essays and working notes on AI systems, materials, and the architectures behind meaningful decisions.

Substack Essays and working notes published as the public thinking layer.
Core theme Information, systems, and the choices that shape life and industry.

6 experiments in 2026.

The build-in-public layer stays intentionally lightweight: small tools, fast loops, direct signals.
