Overview

I built My Debt Coach for young family members juggling payday loans and scattered balances. I had lived that same spreadsheet sprint in my twenties.

One calm ledger for cards, loans, and pay-later plans: compare payoff models, see what is due next, and stay oriented with manual entry.

Product stack at a glance

Consumer app, CMS, and growth APIs on one monorepo. Full engineering notes live in the companion Lab doc.

Next.js

App and portal on one codebase.

Supabase

Auth, Postgres, and per-user data with RLS.

Sanity

Marketing site, Knowledge Base, and blog CMS.

Growth layer

SEO, analytics, Meta and Bluesky APIs, plus the admin intelligence hub.

From balances to a plan you can stick with

Add your debts

Cards, loans, BNPL, and promo APR all live under My Debt so nothing sits in a separate app or email thread.

Plan and compare

Set a monthly budget, pick among seven strategies, and run any two side by side on the Compare tab.

Pay and stay on track

Use the Payments calendar, mark paid or skip, get reminders, and see Next up coaching on Home.

Same monthly budget, two payoff strategies: interest, months to debt-free, and remaining balance.
Buy now, pay later plans stay visible with progress, next dues, and late alerts.
Payments calendar with due coaching: mark paid, skip, or record extra.

Growth is operated from a live hub

The public site is CMS-driven. Day-to-day social and content marketing runs through agent-ready APIs on the admin portal.

Sanity-driven marketing site

Block-based homepage with hero, features, showcases, and FAQ, editable without redeploys.

Knowledge Base + blog

How-to guides, debt education, and blog posts at /knowledge-base and /blog for organic discovery.

SEO & AEO

Canonicals, Open Graph and Twitter cards, JSON-LD, dynamic sitemap, and llms.txt for AI crawlers.

Measured growth

GTM and GA4 with cookie consent, conversion events for demo, signup, and login, plus in-portal blog promos.

Admin intelligence hub

Internal ops brain for product analytics, Meta and Bluesky marketing automation, and agent-run content publishing. Data connector hubs (BigQuery and more) are next.
