The Compute Capital Stack →

The Compute Capital Stack is a public model pricing the risk-adjusted cost of compute per million tokens from filings, accelerator-hours, megawatts, and interconnection-queue data. It links token demand to deliverable capacity, take-or-pay structure, power conversion, and Monte Carlo cost cones.

The source base draws on SEC filings, PJM and ERCOT records, and the LBNL Queued Up dataset. The point is not a single headline number; it is the finance bridge from product demand to capacity, delivery risk, contract exposure, and liquidity consequences.

Alongside it: a tax-loss harvesting engine that runs the realize-and-replace decision against a live market, and analytics for the University of Utah student investment fund.

Background

I have five-plus years spanning SaaS unit-economics underwriting and regulated-bank structured credit. The operating pattern is consistent: build the scenario or stress engine, connect it to the governing source data, and turn it into a decision surface for capital allocation, risk appetite, covenant design, liquidity, or portfolio exposure.

Experience
WEBBANK2025 - 2026
Credit & Counterparty Risk Analyst · Salt Lake City, UT
Owned monthly net real exposure and concentration reporting across a 30+ partner sponsor-bank portfolio and $2B+ capital base, presenting residual exposure, collateral, structural protection, and liquidity impact directly to Chief Risk and Chief Credit leadership.
Built funded and unfunded loss-coverage models across credit-risk-transfer, secured, and unsecured structures; measured residual exposure after collateral, reserves, and structural protection.
Monitored warehouse facilities secured by partner loan portfolios, including vintage-pool exposure, collateral waterfalls, borrowing-base requirements, and product-level concentration across Consumer, Purchase Finance, and SMB.
Stress-tested discount-to-clear and risk-adjusted-margin outcomes under elevated expected loss; owned multi-policy concentration limits, covenant headroom, ECC escalation, and drafted monitored financial covenants.
FAR GRADIENT INC.2024 - Present
Independent Technical Finance Build, Financial Data & Risk Analytics · Salt Lake City, UT
Built the Compute Capital Stack, a public capital-allocation model pricing deliverability-adjusted cost of compute per million tokens by linking token demand, accelerator-hours, megawatts, interconnection-queue conversion, take-or-pay structure, and Monte Carlo cost cones.
Automated financial spreading through a counterparty credit workbench with ML-assisted statement extraction, covenant calculations, coverage KPIs, composite risk scoring, source-precedence governance, and MCP-enabled AI-agent tool access.
Built finance-led scenario and stress-testing engines in Python and Polars with governed source tracking, event logging, source-linked review, and auditable replay.

Credit Analyst -> Senior Credit Analyst, Corporate Strategy (promoted 2024) · Salt Lake City, UT
Built BILL's first enterprise credit-advisory function, owning financial-statement analysis for strategic clients with $20M-$1B+ revenue whose true position was not captured by GAAP alone.
Underwrote on SaaS-native metrics including liquidity runway, cash-burn rate and burn as percent of ARR, NRR, CAC/LTV, and burn multiples to forecast cash-out dates and right-size limits.
Served as direct counterpart to client CEOs and CFOs, pressure-testing revenue engines, contract pipelines, and operating models to validate forward claims and surface latent credit capacity.
Brokered growth-oriented revenue teams and a conservative risk organization across 1,000+ deals; authored 100+ executive exception memos enabling responsible growth without loosening standards.
Built credit-rating predictors and screening tools adopted by Sales; produced portfolio exposure and loss-forecast analysis by score segment.
Institute of Advanced Investment Management2024 - Present
Fund Manager -> Teaching Assistant (promoted 2025) · Salt Lake City, UT
Served as Fund Manager for the inaugural roughly $1.1M student fund; authored and won Investment Committee approval for a strategy redeploying roughly $115K, or 10%+ of AUM.
Built the recommendation on mean-variance optimization, a covariance-estimated risk model, and probability-weighted rate scenarios from CME FedWatch.
Sole teaching assistant and primary instructor in financial modeling and quantitative methods: DCF, LBO, portfolio construction, factor and risk analysis.
Directed the build of the fund operating dashboard and performance tracker for portfolio and risk reporting.
