# Brett Meddaugh: Full AI Context

## Overview
Brett Meddaugh's personal web presence and digital project showcase.
Website: https://brettmeddaugh.com

## Philosophy & Background
Brett is a tech and software tinkerer who focuses on building solid, pragmatic tools. Rather than sticking to single-discipline titles, he builds across whatever areas a project requires: UI/UX, full-stack software, Linux daemons, and AI agent pipelines. Outside of software, Brett coordinates the La Crosse Team Tennis Association (LTTA) summer league, runs a tennis stringing studio, and is an active player and coach.

- **Subdomain:** cars.brettmeddaugh.com (Private / Auth Required)
- **Codebase:** /home/brett/Code/personal/ev-agent-scout
- **Tech Stack:** React 19 + TypeScript + Vite + Tailwind CSS + Express + SQLite
- **Description:** An autonomous multi-agent EV scouting and comparative intelligence platform engineered to discover, audit, and negotiate used electric vehicles across the Upper Midwest (MN, WI, IA, IL), calibrated specifically for a 156-mile round-trip sub-zero winter commute with two rear-facing car seats.
- **Key Capabilities:**
  - 4-stage autonomous multi-agent pipeline: Scout (inventory polling) → Inspector (VIN decoding, recall & accident checks) → Auditor (pricing & dealer fee audits) → Negotiator (fair market valuation & distance arbitrage $/hr return).
  - Sub-zero winter commute telemetry panel featuring a dynamic temperature slider (-20°F to 75°F), 8-year battery aging degradation modeling, and blizzard emergency safety buffer calculations for the Holmen, WI to Elk Mound, WI route.
  - 2D vector dimension visualizer with scale-accurate silhouettes, ghost overlays, human scale reference, and rear car seat clearance checks.
  - AI-powered head-to-head matchup synthesis with fact-checking critic pass and a "Doug DeMuro Quirks" matrix.
  - Multi-user profile consensus scoring (Brett Commuter, Partner Family, Budget Hacker, Tech Enthusiast) with passcode logins.
  - Embedded DeepSeek-powered context-aware AI chat advisor.

### 2. Money (MoneyBoard: Financial Intelligence Cockpit & FIRE Suite)

- **Codebase:** /home/brett/MoneyBoard
- **Tech Stack:** React 19 + Vite + Tailwind v4 + Express + better-sqlite3 + Actual Budget API
- **Description:** An executive-level personal finance intelligence cockpit extending zero-based budgeting in Actual Budget with automated ingestion daemons, transaction normalizers, investment tracking, and interactive retirement modeling.
- **Key Capabilities:**
  - Automated watcher daemon (watcher.js) monitoring SQLite database events in real time to run rules-based sign fixers, transfer matchers, and local Ollama LLM transaction categorization.
  - 2-day sliding window "Smart Read" engine filtering out wash/duplicate transactions and internal transit records.
  - Income normalization factoring in statutory 401(k) and HSA limits for true gross savings rate calculation.
  - Interactive FIRE projection engine featuring 4 Safe Withdrawal Rate (SWR) tiers, What-If scenario sliders (post-retirement income, lifestyle creep, tax impacts across Traditional/Roth/Taxable), and milestone tracking (Coast, Barista, Lean, Full, Fat FIRE).
  - Raise & marginal tax simulator computing net take-home against 2025 Federal, FICA, and State tax brackets.
  - Multi-account investment portfolio tracker with asset allocation cards and account freshness health metrics.
  - Bank PDF/CSV statement ingestion with automatic institution recognition and privacy demo mode with mock data engine.

### 3. Tennis (Tennis String Lab: Stringing Studio & Snapback Physics Simulator)
- **Route:** https://brettmeddaugh.com/tennis
- **Subdomain:** tennis.brettmeddaugh.com (Private / Auth Required)
- **Codebase:** /home/brett/Code/personal/tennis-string-lab
- **Tech Stack:** React 19 + TypeScript + Vite + Tailwind v4 + Express
- **Description:** A dedicated tennis stringing studio and telemetry platform that models hybrid stringbed interactions, snapback friction, tension loss curves, and racquet fleet specs.
- **Key Capabilities:**
  - Hybrid Matcher & Stringing Studio calculating combined spin potential, perceived arm comfort index, and power/control distributions between mains and crosses.
  - Snapback physics engine applying friction reduction algorithms and spin multipliers for shaped mains (triangular, hexagonal, rough) paired with ultra-slick round crosses (e.g. TRU PRO Ghost Wire).
  - Differential tension advisory engine recommending cross tension offsets (e.g. -2 lbs) to optimize sweet spot size and prevent frame distortion.
  - Active Stringing Log and tension life tracker monitoring on-court hours played with real-time elasticity decay warnings (Fresh <10 hrs, Elasticity Dropping 10-14 hrs, Restring Alert 15+ hrs).
  - Racquet Frame Vault managing specifications (weight in grams, head size, swingweight, string patterns) for personal and client racquets (e.g. Wilson Blade 98).
  - Authoritative TRU PRO / Tier One rebrand cross-reference matrix detailing German extrusion formula equivalence across Firewire, Ghost Wire, Black Knight, Tour Status, and Pure Rush.
