League Operations Platform
SFUYSA League Platform
Complete operations platform for South Florida's premier youth soccer association: 4,000+ players, 500+ teams, 50+ clubs. Scheduling, standings, payments, suspensions, and referee workflows. Rebuilt three times over two decades — classic ASP, then PHP, now an AI-assisted modern rebuild. The league left for a national SaaS and came back.
Prediction League SaaS
Noblix
World Cup 2026 prediction league platform. Private leagues, automated live scoring, and real-time leaderboards, built to handle tournament-day traffic spikes.
AI EdTech SaaS
FlashQuizAI
AI-powered quiz and flashcard generation for teachers, trainers, and students. 4,200+ users, 31,000+ pieces of content generated, 120,000+ study sessions completed.
Sports Officiating SaaS
WhistleMate
Assignment and scheduling platform for sports officials and assignors: availability, game assignments, communication, and compliance in one place.
Private Client · Annual Upgrade
Automated Property Profile
Private client tooling for Miami-Dade and Broward property profiles, PDF generation, and portability studies — including cross-county analysis. Actively upgraded every year as county data and tax rules change.
Entertainment Industry Tool
Stageplotter
Interactive stage-plotting software for the live entertainment industry: visual equipment layout and technical rider documentation for venues and production crews.
Sports Analytics SaaS
Football Depth Chart Analyzer
Interactive depth chart and kickoff formation visualizer for football programs — roster management, unit assignments, and drag-and-drop field positioning.
Private Client · Email Ops
Panama Jack Campaign Intelligence
Private internal tooling for Panama Jack that pulled Klaviyo campaign performance into an offline, shareable dashboard — opens, clicks, recipients, orders, email HTML/thumbnails, and CSV export for Excel review. Built with API extraction plus Puppeteer scraping where the public API lacked revenue metrics.
WordPress Engineering
Custom WordPress Plugins
Bespoke WordPress plugins when off-the-shelf blocks fall short — including a dynamic hero carousel for the Chamber Music Society of Palm Beach (cmspb.org). Theme-compatible, editor-friendly, production-hardened.
One lead architect. A bench behind you.
You work directly with Jeff Kurzner — fractional CTO, lead architect, and builder. Behind that is a trusted network of designers, developers, and specialists Mindshaft brings in when a project needs more hands. Systems are documented, hosted, and supported so work continues even when Jeff is on another engagement.
Direct access to leadership
Strategy calls, architecture decisions, and code review go through Jeff — no account-manager layer, no telephone game.

The league that left for a national SaaS — and came back
SFUYSA runs 500+ teams and 4,000+ players on a platform Mindshaft has built and rebuilt over two decades — from classic ASP, to PHP, to a modern AI-assisted re-engineering. When the league moved to GotSport, they lost teams and gained headaches. They came back.
