Project 01

Frisco Web Designs

AI-powered web design agency platform — text-to-website generation with 4 AI providers, CRM, embeddable chatbot builder, and automated client billing.

4 AI Providers 28 Feature Modules 0 Broken Images

Solo developer — designed and built end-to-end

Vue 3 Claude + GPT-5 + Gemini + Z.AI Node.js Express MongoDB Socket.IO Stripe Firebase Auth Twilio Resend Zod GCS Unsplash

Key Features

  • Text prompt generates a complete, conversion-optimized website with real Unsplash images and full design system
  • Runtime AI provider switching with circuit breakers — 3 failures in 60s trips the circuit, requests fail fast
  • Embeddable AI chatbot with function-calling lead capture, HMAC-signed webhooks, and Twilio SMS alerts
  • Full CRM pipeline — CSV import, 15+ lead statuses, priority scoring, one-click mockup generation

Engineering Highlights

  • Circuit Breaker pattern — Per-provider OPEN→HALF_OPEN→CLOSED state machine prevents cascade failures
  • Zero broken images — 3-tier fallback: memory cache → MongoDB → Unsplash API → deterministic seeds
  • Structured AI via Zod — All LLM output validated with z.union() and safeParseOrDefault() for graceful degradation

Project 02

Define Your Dollars

Personal finance SaaS with AI-powered bank statement analysis, debt payoff planning, and 6 AI coach personalities. Freemium model with Stripe subscriptions and native mobile apps.

1K+ Users 80% Faster Processing 0 Parsing Failures

Solo developer — designed and built end-to-end

Key Features

  • Automates budgeting by extracting and categorizing transactions from uploaded bank statements using Claude AI
  • Cross-statement reconciliation detects transfers across checking, savings, and credit cards with confidence scoring
  • Debt payoff projections with avalanche/snowball comparison and monthly battle plan export
  • Stripe-powered freemium model with iOS/Android apps via Capacitor 7

Engineering Highlights

  • Reduced AI costs ~80% — Hybrid pipeline sends first 100 rows to Claude, then pattern-matches the rest locally
  • 0% parsing failures in production — Strict Zod schemas on Claude tool_use output eliminate hallucination errors
  • 5-stage aggregation pipeline — Normalize → detect transfers → deduplicate → merge recurring → extract entities

Project 03

PropPal

AI-powered aviation maintenance knowledge system — RAG-based Q&A with CFR 43.3 regulatory compliance, dual-mode AI querying, Pinecone vector search, and module-based purchasing.

3072-dim Vectors Dual-Mode AI CFR 43.3 Compliant

Solo developer — designed and built end-to-end

Vue 3 OpenAI GPT-4 + Gemini Pro Node.js Express MongoDB Pinecone Bull Queue Redis Stripe Firebase Auth GCS

Key Features

  • Dual-mode Q&A — quick vector search (5-15s) or complete analysis with Gemini Pro vision for diagrams and schematics (30-60s)
  • Every answer structured as Situation → Briefing → Full Write-Up → CFR 43.3 Analysis → References with deep links
  • Aircraft-specific content modules with per-role pricing, Stripe Checkout, and entitlement tracking
  • Async job queue with Bull + Redis — priority queues, exponential backoff retry, and progress streaming

Engineering Highlights

  • Ports & Adapters AI architecture — Swappable OpenAI and Gemini adapters behind a common interface with graceful degradation
  • Vector search with Pinecone — 3072-dimension embeddings, namespace-per-manual, metadata filtering, and BM25 fallback
  • Safety-first answer generation — Citation validation, confidence thresholds, warning preservation, and CFR 43.3 compliance checks

Project 04

OriginSmith

Gaming tools platform — AI-powered Kenshi character/story generator with community quirk submissions, and a Project Zomboid server mod manager with Steam Workshop integration.

5-Stage Parser 50 Retry Validation 7-Day TTL Cache

Solo developer — designed and built end-to-end

Key Features

  • Kenshi character generator with race/weapon/faction compatibility validation across 5+ constraint rules
  • AI-generated first-person origin stories with interactive keyword highlighting via inline markers
  • Community quirk submissions with admin approval workflow — approved quirks enter the live pool
  • PZ mod manager imports Steam Workshop collections, auto-extracts Mod IDs with 5-stage parser

Engineering Highlights

  • Compatibility validation engine — 50 retry attempts to find valid race/faction/weapon/quirk combinations
  • Throttled Steam API — p-queue with 1 concurrency + 200ms interval, batches of 100, Cheerio scrape fallback
  • Themed rate limiting — 6 tiers with game-flavored error messages ("The scribe needs a moment to rest")
