Work

Proof, not a gallery.

Real products, shown as teardowns: the problem, the system, the decisions. No invented clients, metrics, or testimonials.

FollowUpOS

A follow-up operating system

Problem

Leads and relationships get lost because follow-up depends on memory. Pipelines live in heads, inboxes, and good intentions.

System

Pipeline, reminders, AI-assisted drafts, relationship memory, and a Chrome extension direction, built so the next follow-up is never a memory test.

Key decisions

  • Reminders before automation: remove the forgetting, keep the human.
  • AI drafts assist; the sender always stays in control.
  • Relationship memory over a contact database.
  • Boring enough to be used every day. That is the point.

DealSharp

Real estate deal analysis, productized

Problem

Real estate decisions ride on unclear numbers. Deal analysis lives in one-off spreadsheets nobody trusts twice.

System

Calculators, dashboards, deal review logic, and portfolio thinking, with a financial background translated into software.

Key decisions

  • Numbers first, interface second.
  • Each calculator answers one real decision.
  • Audit thinking baked into the review flow.

The build process

OpsBuild Method

How projects move from messy idea to usable system: map, find the leak, scope, build, test, hand off.

Everything here is internal product work, framed honestly. When client systems ship, they will appear the same way: problem, system, decisions.
