ARIA: FinOps AI Agent

A conversational analyst for cloud spend. Ask “which subscriptions are over budget this fiscal year?” in plain English and get an answer traced to live data, with a link back to the exact filtered view. ARIA stores no cost data of its own; it orchestrates the FinOps Reporting Platform and GCP Spotlight through 30 read-only tools, executed concurrently, over Claude Sonnet on Vertex AI with extended thinking.

The hard problem wasn’t answering questions; it was making a fabricated number structurally impossible. Three independent guard layers (prompt rules, a post-response code check that rejects dollar figures when no tool succeeded, and tool errors that instruct the model not to guess) plus server-side pre-computed totals so the model never does arithmetic. Full audit log, per-user rate limiting, and zero stored API keys via Workload Identity.

GCP Spotlight

Unified FinOps platform that analyzes cloud resource efficiency across an entire GCP organization, covering Kubernetes clusters, virtual machines, cloud storage, and AI workloads in a single pane of glass. Four service modules: GKE (59 clusters, adaptive right-sizing with 25–45% headroom by workload variability), GCE (2,222 VMs, idle detection, CUD coverage analysis), GCS (2,989 buckets, lifecycle optimization, egress monitoring), and AI/Vertex AI (model spend, anomaly detection, chargeback by project).

Full-stack build: Python FastAPI backend (123 API endpoints), React/TypeScript/Tailwind frontend (13 pages, 61 components), three isolated SQLite databases with WAL mode, and a hybrid cost model that layers BigQuery billing data, derived per-unit rates, and on-demand fallback pricing. Deployed to GKE via ArgoCD with Workload Identity and Terraform IAM across ~600 monitored projects.

FinOps Reporting & Budget Platform

Replaced manual spreadsheet reporting with an automated cloud spend platform covering $48M+ in annual spend across AWS, Azure, and GCP. Pulls actuals directly from the Ternary API and normalizes data across 100+ subscriptions via configurable alias maps, with no manual exports. Eight analysis tabs: MoM/YoY movers, anomaly detection, rolling forecasts, budget variance, year-end projection, and COGS analysis.

Solution Scorecard grades every subscription A+–D− across five weighted dimensions, with over-budget penalized at 2× to reflect real financial risk. The entire system thinks natively in fiscal years (July–June): date pickers, scorecards, forecasts, and budget entry all roll over automatically on July 1. Dual PostgreSQL databases keep vendor spend isolated from core financials.

Personal App · Finance Live

Budget G.P.A.

Personal finance mobile app that grades your financial health like a report card: a letter grade and a 4.0-scale GPA across five weighted pillars, adapted from the corporate budget scorecard methodology I built professionally. Live on Google Play and the App Store: 35+ screens, 12 Supabase Edge Functions, and a scoring engine with provisional grades, transfer detection, and a monthly Report Card Day reveal.

Five-pillar scoring: Budget Adherence (35%), Financial Safety (25%), Spending Stability (15%), Needs vs. Wants (15%), and Forecast Accuracy (10%). Automated bank sync via Plaid, AI transaction classification using the Claude API, savings goals, debt payoff modeling, subscription auto-detection, and a RevenueCat paywall with server-owned entitlements. iOS and Android from one codebase.

Personal App · Discovery In Store Testing

Local Haunts

Discovery app for independent restaurants: map and list, chains filtered out, ranked to surface the place around the corner rather than the famous place downtown. Built for six countries (US, Canada, Australia, New Zealand, Singapore, Hong Kong), chosen on legal exposure rather than market size.

Every search runs twice against Google Places, once by distance and once by prominence, then merges the two; in testing that turned 20 landmarks into 30-odd neighborhood places. Chains are removed by a country-scoped blocklist plus a learned location count. One-tap Vouch and Crown signals replace reviews, so there is no moderation burden. RevenueCat Pro with server-owned entitlements, an HMAC-signed photo proxy, and in-app account deletion.

gwf.ninja: Personal Website

Designed and built this personal portfolio site entirely from scratch with no templates and no frameworks. Originally created in 2021 while learning HTML, CSS, and Sass. Redesigned in 2026 with a modern, responsive layout, subtle animations, and a clean dark-to-light aesthetic. Hosted on AWS S3 and served via CloudFront.

The 2026 redesign was built in collaboration with Claude (Anthropic), using AI as a development partner to accelerate the build while keeping the codebase in plain HTML, CSS, and JavaScript with no frameworks.
