Everything Massfeller LLC publishes. Each one made for someone specific.
A private relationship dashboard for one household. Eight years of communication, music, and shared life, collapsed into the screens that two specific people open every morning.
Forensic-grade race timing for 1:64 scale Hot Wheels tracks. ESP32-S3 firmware, sub-millisecond timing, audio cues, physics teaching mode. Originally built for a sixth-grade science fair.
A touchscreen jukebox and tip jar for mobile DJs. The crowd browses the catalog on a booth-facing screen, tips to request a song, and pays by scanning a Stripe QR — while the DJ runs the night from an iOS app over BLE.
Multi-tenant golf league management for head pros. AI-assisted scheduling, scoring, and season operations — the platform built to retire the spreadsheet and Golf Genius. The one thing here built to be sold. TPS League is tenant #1.
A full golf league running in production on Par72 — schedules, scoring, GHIN handicap sync, pairings, and course rotation across thirty-nine Front Range courses. Proof the platform runs a real season, not a demo.
Automated grade verification and homework accountability for parents. Pulls assignment data, detects grading errors, tracks submissions, delivers daily reports to the whole family.
When Massfeller LLC ships additional apps under the same umbrella, they will appear here with their own pages. None are publicly announced.
