Compose
Separate what should vary from what should stay dependable.

Questions become models. Models become code. Reality tests both.

Noetrium
Open sourceA research OS for programmable agent experiments with durable identity, replay, recovery, and evidence.
AnchorBell
EngineeringA Rust-first quantitative engine for deterministic replay, execution, market microstructure, and adaptive risk.
Charterion
Open sourceA local-first control plane for durable, role-based multi-agent engineering with isolated work and review.
Method
Build the question
into the system.
Make assumptions explicit enough that software, experiments, and evidence can disagree.
Measure
Turn behavior into observable state and controlled comparison.
Verify
Preserve provenance and evidence so results can be challenged.
About
From the unknown,
through zero,
toward infinity.
I work across open-source systems research, mathematical modeling, and reliable engineering, with projects ranging from AI research infrastructure to quantitative and engineering systems.
I prefer ideas that survive translation into models, code, experiments, and real operating constraints.
Why “Xalzeroph”?Identity note
Xalzeroph begins with X, the algebraic unknown. Within the name, ZERO remains intact; ALEPH is preserved in sequence — A–L–E–P–H — with both sharing the same E. Their overlap evokes ℵ₀, aleph-zero: the first infinite cardinal, the cardinality of the natural numbers.
The name has a literary echo, too. In Borges, the Aleph is a single point containing every other point — the infinite held within the singular.
