LEDGER — CASE FILES · ALL VALIDATED

Four systems, four different industries — the same fixed-scope process.

Every engagement below is live in production today, not a mockup or a pitch. Real clients, real links, real outcomes.

PropTech · Operations Platform

Sablecrest Property Management

Manual email ops Automated client platform

Sablecrest was running client intake, requests, and updates entirely by hand through email. I replaced that with an automated client platform so residents and owners get answers instantly instead of waiting on a reply.

"Our whole intake and communication process is now automated. Clients get answers instantly and we spend less time chasing forms."— Sablecrest Property Management

Startup · Zero to Launch

Community Platform — R3

Idea on paper Live platform, 50 users in week 1

R3 needed to go from a written idea to an investor-ready product fast, without cutting corners on quality. I scoped, built, and shipped a live platform that had real users signed up in its first week.

"Needed to ship fast without sacrificing quality. Jay delivered a system I'm actually proud to show investors."— Founder, R3

Data Engineering · Analytics Platform

Digital Asset Analytics — RipplePunks

Scattered chat updates Live market data for 10,000 punks

RipplePunks' community was tracking asset data through scattered chat messages with no single source of truth. I built a real-time analytics platform tracking all 10,000 assets, so holders can see live numbers instead of rumors.

"Jay took our community from scattered updates to a real-time data platform. Holders now trust the numbers."— RipplePunks Team

Consumer App · iOS + Android

Echo Studio — Live Events App

Concept Shipped to the App Store & Google Play

Echo Studio is a collaborative concert video and revenue-sharing app. I engineered the mobile app, backend, payments, and subscriptions end to end, plus a cinematic marketing site — one build across iOS, Android, and web.
