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.

Problem
Email-based client intake, requests and updates.
What was built
An automated client platform.
Approach
Connected intake and communication workflows.
Result
Clients can access answers and updates through the platform.
"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.

Problem
A community product starting as a written idea.
What was built
A live community platform.
Approach
A defined scope and focused build-to-launch process.
Result
A working platform with users 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.

Problem
Asset updates scattered across community chat.
What was built
A real-time asset analytics platform.
Approach
A shared data view covering the collection.
Result
A single place to view asset data.
"Jay took our community from scattered updates to a real-time data platform. Holders now trust the numbers."— RipplePunks Team

Approach
