Over a decade across enterprise SaaS, biotechnology, healthcare, and public-company security work β now building FAIR-based risk quantification, compliance-as-code, and AI-assisted GRC systems that replace the audit spreadsheet with something a board can actually read.
I architect and engineer the platforms myself: React/Vite front ends, Node.js/Express services, PostgreSQL data models, and evidence pipelines that pull continuous control evidence out of cloud infrastructure, IdPs, EDRs, and ticketing systems instead of asking a human to screenshot it.
| What it means | Where it shows up | |
|---|---|---|
| 01 Β· Quantify | Turn cyber risk from a heat-map color into a defensible loss-exposure range. FAIR-based scenarios, LLM-assisted scoring, and P50 / P90 narratives that let leadership decide instead of react. | FAIR Β· Monte Carlo Β· LLM scoring Β· Executive narrative |
| 02 Β· Engineer | Make controls, evidence, and frameworks one operating system β not five parallel spreadsheets. OSCAL-shaped data, compliance-as-code checks, and evidence pipelines that arrive with the work. | OSCAL Β· Compliance-as-code Β· Evidence automation Β· Control platform |
| 03 Β· Translate | Move technical exposure into materiality decisions leaders can defend. OWASP + EO-14028 severity, SEC 8-K disclosure workflows, and calculators that keep the reasoning legible after the incident. | SEC 8-K Β· EO-14028 Β· Materiality Β· Incident severity |
Controls are the foundation. Everything else pulls from the controls. Build controls out properly and audit evidence, risk, policy, and compliance automatically compose. Miss the layer a control sits at β product, platform, customer, enterprise β or what it costs to own, and you'll never calculate risk, mature controls, set realistic KRIs/KPIs, or run continuous monitoring. Bad control data is the path to a failing GRC program.
Financial quantification in GRC is non-negotiable. Heatmaps are dead. Red is a color, not a unit of risk measurement. You cannot tell leadership "how risky" something is by calling it red. FAIR gives you defensible loss exposure ranges a CFO can budget against.
Risk is not a point in time. Risk is scenarios. Static risk registers are legacy. We run scenarios, Monte Carlo simulations, and loss exceedance curves to show where threats actually live. When risk is forward-looking instead of reactionary, you have a mature program.
GRC engineering and automation take programs to the next level. Manual workload eventually takes its toll and fatigue causes error. Automate the workflows and engineer the solutions β AI for risk scoring, questionnaire response, vendor assessment, and threat modeling. AI and engineering take already-mature programs to the next level, and give struggling teams a shortcut to the top.
| Project | What it does |
|---|---|
u-dont-grc-me TypeScript |
Control-centric GRC platform prototype β controls are the source of truth, with assets, frameworks, evidence, risks, integrations, and AI agent decisions mapped around each one. Command center, audit package assembly, and a 10,000-trial FAIR Monte Carlo engine. React/Vite UI over a SQLite/Lambda API. Live |
ai-risk-register HTML |
An AI risk register that returns loss exposure ranges instead of heat-map colours. Twelve seeded AI scenarios, three-point estimates through a 10,000-iteration Monte Carlo, and live coverage against NIST AI RMF 1.0 and ISO/IEC 42001 Annex A. Live |
cyber-materiality-workbench HTML |
Work an incident through an SEC Item 1.05 materiality determination β the quantitative screen, the SAB 99 total mix, the four-business-day clock counted against federal holidays, and the contemporaneous memo. Either leg can carry the call, which is the whole point. Live |
incident-severity-calculator HTML |
Sixteen OWASP Risk Rating factors, likelihood and impact kept separate, severity read from the OWASP matrix with the active cell shown live. One rubric, so the argument becomes "you scored detection at 9 and I scored it at 3." Live |
risk-quantifier HTML |
Place risks on a 5Γ5 heat map, give each a frequency and loss range, then run 10,000 Monte Carlo iterations and watch the matrix become a distribution. Built to show exactly how much information a qualitative matrix throws away. Live |
loss-exceedance-curve HTML |
Interactive LEC guide. Overlay risk tolerance, loss reserves, and materiality to read the odds of crossing each one β the answer to "what are the chances we lose more than $X?" Live |
fair-model-study HTML |
Interactive FAIR taxonomy trainer: build the decomposition tree from memory, assign units, match 22 definitions. Placement and unit accuracy scored separately. Live |
monte-carlo-demo HTML |
Watch the law of large numbers converge on a fair coin, with the binomial standard-error band drawn in. Ten flips land anywhere; ten thousand settle down. Live |
