Selected work.

I've been shipping software since 2016: founding iOS engineer at Ohmyhome (now Nasdaq: OMH), senior systems engineer and team lead through a $300k to $1M a month scale-up, and today the engineer behind my own products. Here's what I've built lately, what I owned, and the calls I made along the way.

The problem

I wanted my playbooks to teach by doing, not by reading. That meant lessons with real tools inside them, paid access that holds up, and one login across my sites.

Key decisions

  1. 01

    Money logic lives on the server

    Monthly, annual and lifetime plans plus guest checkout, fulfilled by Stripe webhooks. A double-purchase guard, and entitlements verified server-side, so access follows the actual subscription or purchase.

  2. 02

    Paid content never reaches a free browser

    I caught locked lesson content being sent to every visitor and only hidden in the UI. I moved paid content into server-only modules and rolled the fix out one playbook at a time.

  3. 03

    One identity across subdomains

    Password, Google and magic-link sign-in, with one shared session across abiemaxey.com and the portal.

  4. 04

    Onboarding that picks the path

    A profile flow recommends the right playbook, progress is saved per user, and the free trial went from 7 to 30 days so people reach value before the paywall.

Case 02 ~ 2026

Growth OS

The CRM I run my pipeline on: who to chase, the exact next move, and what's owed today.

Sole engineer and daily user.

The problem

Two businesses, one inbox. Brand deals and consults were slipping because the next move lived in my head.

Key decisions

  1. 01

    Isolated schema, read-only production

    The CRM lives in its own schema and only reads the production funnel tables, so a CRM bug can never touch live business data.

  2. 02

    Pure, tested business rules

    Priority and revenue logic are pure functions with unit tests, shared by the board, the morning brief and the sync.

  3. 03

    Agents propose, I approve

    An AI agent drafts replies in my voice and suggests leads from my funnels and from Reddit and Threads. Nothing reaches the board until I approve it in a review queue.

  4. 04

    Email history per lead

    Gmail sync stores each lead's thread history in the database, so the agent reads context there instead of re-fetching mail.
