Asset Integrity Engineer
RBI Decision Systems • Engineering Data Architecture • Physics-Constrained ML • Secure Automation

Engineering Profile

I design and implement decision-support systems for asset integrity and risk-based inspection (RBI) programs.

My work operates at the boundary between engineering judgment, structured data systems, and applied machine learning. The objective is not algorithmic novelty — the objective is defensible operational decisions.

Systems are built to ensure:

  • Explicit assumptions
  • Transparent transformation logic
  • Inspectable data lineage
  • Bounded model behavior
  • Visible failure modes

System Architecture Philosophy

flowchart TD
    A[Physical Reality] --> B[Structured Engineering Data]
    B --> C[Explicit Domain Logic]
    C --> D[Physics / Risk Framing]
    D --> E[Validation Harness]
    E --> F[Operational Decision Support]
Loading

Engineering judgment is preserved — not replaced.
Automation reduces ambiguity, not accountability.

Architectural priorities:

  • Schemas aligned with physical meaning
  • Validation at ingestion
  • Deterministic transformations
  • Version-controlled logic
  • Full audit trail

Data quality is treated as an engineering risk variable.

Technical Stack

Primary language: Python, HTML, Javascript
Design emphasis: Reproducibility • Auditability • Determinism

Engineering Principles

If an assumption is not written, it will fail silently.

If data lineage is not explicit, the decision is not defensible.

If a model cannot define its boundary conditions,
it is not operational.

Integrity Code Series

Open-source physics-first integrity simulators. Each entry is a self-contained Python package with governing PDEs/ODEs documented in code, analytical benchmarks against textbook constants, a Monte Carlo layer over the deterministic model, and a run_all.py entry point that reproduces every figure.
