Projects That Speak for Themselves

Challenge

Building a complete two-sided marketplace with real-time messaging, secure P2P payments with escrow, and a mobile-first experience — without native app development or a large dev team.

Solution

Delivered a full-featured Next.js PWA across 6 development phases using AI-accelerated workflows. Stripe Connect handles P2P payments, WebSocket powers real-time messaging, and service workers enable push notifications.

Results

• 6-phase MVP delivered in weeks
• PWA with native-like experience
• Secure P2P payments via Stripe Connect
• Complete review & trust system

Challenge

Needed to scrape and parse city street sweeping schedules, match addresses to zones, and deliver timely notifications via email and SMS — all with a clean signup flow and subscription billing.

Solution

Results

• Deployed to production on Railway
• Automated email notifications live
• Stripe subscription billing integrated
• Custom domain at salemsweeper.com

Challenge

Aggregating multiple property data sources into a single, fast, developer-friendly API with proper rate limiting, usage metering, and tiered subscription pricing.

Solution

Architected a FastAPI application with PostgreSQL and Redis caching. Stripe handles subscription tiers with usage-based billing. Deployed with a marketing site on propertypulse.dev.

Results

• Phase 1 deployed to production
• Full API documentation site live
• Tiered pricing with Stripe integration
• Sub-200ms response times with Redis

Challenge

The county publishes burn status in formats that aren't user-friendly. Residents needed a quick, mobile-friendly way to check before lighting a burn pile.

Solution

Results

• Live at caniburn-mc.com
• Automated daily status scraping
• Simple, mobile-friendly interface
• Deployed on Railway

Challenge

Vehicle data is fragmented across dozens of sources with inconsistent formats. Needed to normalize this into a clean, fast API with proper authentication and rate limiting.

Solution

Developed a FastAPI application with SQLAlchemy models for vehicle data, Redis caching for performance, and Stripe for API key subscription management. Comprehensive endpoint coverage across maintenance, diagnostics, and safety data.

Results

• Core implementation complete
• Covers maintenance, oil, diagnostics, recalls & TSBs
• Redis-cached for fast responses
• Stripe-powered API key management

Challenge

Creating an intuitive search experience that presents complex property data in a digestible format, with fast autocomplete and responsive design across all devices.

Solution

Results

• Live on Vercel
• Real-time address autocomplete
• Rich property data display
• Responsive across all devices

Challenge

Government permit data is scattered across multiple portals with inconsistent HTML formats and no public API. Developers and proptech companies need normalized, queryable access to this data.

Solution

Built a FastAPI application with custom scrapers for the Salem PAC Portal, Marion County ArcGIS, and Compliance Services. Data is normalized into a unified schema with Redis caching, Stripe subscription billing, and sliding-window rate limiting.

Results

• Phase 1 complete with full data pipeline
• 3 government data sources integrated
• 4-tier billing from free to enterprise
• Domain secured at permitsdata.com

Challenge

People often don't know whether their symptoms warrant an ER visit or a simple urgent care trip — and not all urgent care centers handle the same conditions. This leads to wasted time, money, and delayed care.

Solution

Integrated Claude Sonnet for real-time symptom triage with ER escalation warnings. Built a facility database with 17 capability types and a match-scoring algorithm. Leaflet maps show results with capability badges, and the app works offline as a PWA.

Results

• AI symptom triage with ER escalation
• 12 facilities with capability matching
• Interactive map + list view
• PWA-ready with dark/light themes

Challenge

Building a massive library of accurate, interactive calculators that load fast, look great, and are individually SEO-optimized — while supporting user accounts, saved calculations, and monetization.

Solution

Architected a Next.js 16 app with a modular calculator registry system. Each calculator is a self-contained component with Recharts visualizations, jsPDF export, and Stripe-powered premium access. Framer Motion provides polished animations throughout.

Results

• 100+ calculators across 30 categories
• PDF export for all calculations
• Premium tier with Stripe billing
• User accounts with saved history

Challenge

Creating an elegant, conversion-focused event site that handles ticket sales, captures registrations, and presents sponsor information — while reflecting the prestige of a long-running community fundraiser.

Solution

Built a Next.js 16 site with Square payment integration for ticket purchases, NextAuth for user accounts, and a golf-inspired dark theme with gold accents. Framer Motion scroll animations create a premium feel throughout.

Results

• Live at kostersaygolf.com
• Square-powered ticket sales
• Animated premium golf aesthetic
• 20+ years of tournament history

Challenge

Small businesses juggle separate tools for proposals, contracts, invoicing, and payments. This fragmentation causes lost deals, slow payments, and administrative overhead.

Solution

Built a full-stack Next.js SaaS with a drag-and-drop proposal editor, legally binding e-signatures, one-click invoice generation from accepted proposals, and integrated Stripe payments. Includes real-time analytics on proposal views and client management.

Results

• Complete quote-to-cash workflow
• E-signatures with legal compliance
• Stripe-powered instant payments
• Free and Pro subscription tiers

Challenge

Running a squares pool traditionally means spreadsheets, manual score tracking, and group chats full of confusion. There was no simple, free tool to create, share, and auto-score a squares game online.

Solution

Built a Next.js app with real-time ESPN score integration for NCAA games, CSV import for bulk player entry, automatic payout calculations, and shareable game links that require no account to view. SendGrid handles notifications.

Results

• Auto-updating ESPN scores for NCAA
• CSV import/export for player grids
