π Design Your Entire Schema in 30 Minutes
Stop overthinking. Your schema just needs to work, not win awards.
The Universal SaaS Schema:
Schema Anti-Patterns to Avoid:
β Over-normalization - Not everything needs its own table
β Premature optimization - Don't index everything
β Complex relationships - Start with foreign keys, add complexity later
β Perfect naming - You can rename later
The JSONB Escape Hatch:
Real Developer Wisdom:
"Spent 2 weeks designing perfect schema. Rewrote it day 2 of production anyway." - Tom K.
"Ship with 5 tables. We're at 500K users, still have 12 tables." - Maria S.
Your Schema Challenge:
Draw your schema on paper. Take a photo. Share it.
No SQL yet. Just boxes and arrows. 5 minutes max.
Tomorrow: Deployment options that won't break the bank.

Stop overthinking. Your schema just needs to work, not win awards.
The Universal SaaS Schema:
-- 90% of SaaS apps need exactly this
CREATE SCHEMA app;
-- Users & Auth
CREATE TABLE app.users (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
email CITEXT UNIQUE NOT NULL,
password_hash TEXT,
verified BOOLEAN DEFAULT FALSE,
metadata JSONB DEFAULT '{}',
created_at TIMESTAMPTZ DEFAULT NOW()
);
-- Your Core Entity (projects/documents/whatever)
CREATE TABLE app.items (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
user_id UUID NOT NULL REFERENCES app.users(id),
title TEXT NOT NULL,
content TEXT,
data JSONB DEFAULT '{}',
status TEXT DEFAULT 'active',
created_at TIMESTAMPTZ DEFAULT NOW(),
updated_at TIMESTAMPTZ DEFAULT NOW()
);
-- Events/Analytics
CREATE TABLE app.events (
id BIGSERIAL PRIMARY KEY,
user_id UUID REFERENCES app.users(id),
event TEXT NOT NULL,
properties JSONB DEFAULT '{}',
created_at TIMESTAMPTZ DEFAULT NOW()
);
-- Indexes for speed
CREATE INDEX ON app.items(user_id, created_at DESC);
CREATE INDEX ON app.events(user_id, created_at DESC);
Schema Anti-Patterns to Avoid:
β Over-normalization - Not everything needs its own table
β Premature optimization - Don't index everything
β Complex relationships - Start with foreign keys, add complexity later
β Perfect naming - You can rename later
The JSONB Escape Hatch:
-- Can't decide on columns? Use JSONB
ALTER TABLE items ADD COLUMN data JSONB DEFAULT '{}';
-- Now you can add any field without migrations
UPDATE items SET data = data || '{"color": "blue", "size": "large"}';
-- Query it like normal columns
SELECT * FROM items WHERE data->>'color' = 'blue';

π‘ The Simplicity Test:
Can you explain your app in one sentence?
"Save links with tags"
"Track daily habits"
"Create and send invoices"

π DECEMBER WEEK 1: COMPLETE
If you followed along, you now have:
β PostgreSQL database running
β Authentication working
β Core feature functional
β Deployed somewhere real
That's more than most "I'll build something" promises ever become.
---
π COMMUNITY PULSE
Builders who started: 200+
First deploys shared: 47
"It works!" messages: still counting
Not everyone finished. That's fine.
Week 2 is where stragglers catch up
and leaders pull ahead.
---
π― WEEK 2: FEATURE WEEK
This week we add the parts that
turn a project into a product:
Mon: Transition + catch-up day
Tue: Payment concepts (the traps to avoid)
Wed: π° Complete Stripe billing system
Thu: Analytics & feedback loops
Fri: Demo Friday #2
---
The difference between a side project
and a SaaS is one thing:
Someone can pay you.
Week 2 makes that happen.
---
Week 1 builders: take today to clean up.
Week 1 stragglers: perfect day to catch up.
Tomorrow we talk money. πΈ

πΈ THE PAYMENT INTEGRATION TRAP
Every developer building SaaS hits this wall:
"Time to add payments"
β Google "Stripe integration tutorial"
β 47 different approaches
β 3 days later: spaghetti code
β Still missing edge cases
Sound familiar?
---
WHAT TUTORIALS TEACH
- Create checkout session β
- Handle success redirect β
- Done! Ship it! π
WHAT TUTORIALS SKIP
- Webhook signature verification
- Subscription state management
- Failed payment recovery
- Plan changes mid-cycle
- Usage-based billing
- Refund states
- Customer portal sync
- Race conditions
The "2 hour integration" becomes 2 weeks.
---
THE REAL PROBLEM
Most devs treat Stripe as the source of truth.
Wrong.
Your PostgreSQL database is the source of truth.
Stripe is just the payment processor.
This means:
β Every webhook updates YOUR tables
β Subscription status lives in YOUR schema
β Access control queries YOUR data
β You can switch processors without rewriting
---
THE SCHEMA MISTAKE
---
Tomorrow: the complete system.
Production schema + all webhook handlers + subscription lifecycle + access control middleware.
The billing system I actually use.
One time purchase, forever yours.

ALTER TABLE users
ADD COLUMN stripe_customer_id TEXT,
ADD COLUMN subscription_status TEXT;
-- Breaks when:
-- User has multiple subscriptions
-- Team billing (one payer, many users)
-- You need subscription history
-- Plan changes mid-cycle

PostgreSQL Pro | Database Mastery pinned Β«π COMPLETE STRIPE + POSTGRESQL BILLING Stop copying broken tutorials. Ship production billing today. --- WHAT'S INSIDE π¦ Production Database Schema 6 tables handling every edge case: customers, subscriptions, invoices, payments, webhook events, plan featuresβ¦Β»
π DAY 10: KNOW YOUR USERS
You've got auth. Maybe payments now.
But do you know what users actually do?
Today: analytics that live in YOUR database.
---
THE THIRD-PARTY TRAP
Mixpanel: $25/month β $200/month β $1000/month
Amplitude: "Contact sales"
Google Analytics: Free but... Google
For early-stage SaaS, you need:
- Who signed up
- Who's active
- Who's paying
- Who's leaving
PostgreSQL handles all of this.
---
SIMPLE EVENT TRACKING
That's it. Now track anything:
---
QUERIES THAT MATTER
Daily active users:
Feature adoption:
Users at risk (no activity 7+ days):
---
COST COMPARISON
PostgreSQL analytics: $0/month
Mixpanel at scale: $500+/month
You own the data.
You control the queries.
You pay nothing extra.

INSERT INTO user_events (user_id, event_name, properties)
VALUES (
$1,
'feature_used',
'{"feature": "export", "format": "csv"}'
);
---
QUERIES THAT MATTER
Daily active users:
SELECT DATE(created_at), COUNT(DISTINCT user_id)
FROM user_events
WHERE created_at > NOW() - INTERVAL '30 days'
GROUP BY 1 ORDER BY 1;
Feature adoption:
SELECT
properties->>'feature' as feature,
COUNT(DISTINCT user_id) as users
FROM user_events
WHERE event_name = 'feature_used'
GROUP BY 1 ORDER BY 2 DESC;
Users at risk (no activity 7+ days):
SELECT u.id, u.email, MAX(e.created_at) as last_seen
FROM users u
LEFT JOIN user_events e ON u.id = e.user_id
GROUP BY u.id
HAVING MAX(e.created_at) < NOW() - INTERVAL '7 days'

π HALFWAY CHECK-IN
We're 2 weeks into December.
Some of you have:
β Working app deployed
β Auth system running
β Maybe even payments
Some of you have:
π Half-finished features
π "I'll catch up this weekend"
π Scope creep taking over
Both are normal. Here's what matters now.
---
π― WEEK 3: LAUNCH PREP
This week isn't about building more features.
It's about getting ready to show real humans
what you've built.
Mon: Reset and refocus
Tue: The minimum viable launch
Wed: π° Solo dev launch toolkit
Thu: Getting your first 10 users
Fri: Demo Friday #3
---
THE SOLO DEV REALITY
You don't need:
β Perfect landing page
β Complex billing system
β Analytics dashboard
β 47 features
You need:
β Something that works
β A way to collect emails
β A way to talk to users
β Courage to share it
---
THIS WEEK'S MISSION
By Friday, have ONE link you can share
that lets someone try your thing.
Not perfect. Not complete.
Just real enough to get feedback.

π THE MINIMUM VIABLE LAUNCH
What do you actually need to launch?
Spoiler: Way less than you think.
---
THE INDIE HACKER LAUNCH STACK
Successful solo devs launch with:
1. Landing page (1 hour)
- Headline explaining what it does
- 3 bullet points of benefits
- Email signup or "Try it" button
- That's it.
2. Waitlist/signup (30 min)
- Collect email
- Maybe collect one more field
- Send confirmation
- Done.
3. The actual thing (you have this)
- It works, mostly
- It solves one problem
- Someone can use it
4. Feedback channel (10 min)
- Simple form
- Or just your email
- Or a Telegram/Discord link
---
WHAT YOU DON'T NEED
β Perfect design (ship ugly, iterate later)
β All features done (launch with 20%)
β Pricing figured out (offer free access first)
β Legal pages (add them week 2)
β Custom analytics (check server logs)
β Complex onboarding (just let them use it)
---
THE POSTGRESQL ADVANTAGE
Your database can handle launch day with
zero extra services:
No Mailchimp. No Typeform. No Mixpanel.
Just PostgreSQL.
---
Tomorrow: Complete launch toolkit.
Waitlist with referral tracking.
Feedback widget.
Launch day dashboard.
All PostgreSQL. All simple.

Your database can handle launch day with
zero extra services:
-- This is your entire waitlist system
CREATE TABLE waitlist (

email TEXT UNIQUE NOT NULL,
source TEXT,
created_at TIMESTAMPTZ DEFAULT NOW()
);
-- This is your feedback system
CREATE TABLE feedback (
id SERIAL PRIMARY KEY,
user_email TEXT,
message TEXT NOT NULL,
page_url TEXT,
created_at TIMESTAMPTZ DEFAULT NOW()
);
-- This is your launch analytics
SELECT DATE(created_at), COUNT(*)
FROM waitlist
GROUP BY 1 ORDER BY 1;
No Mailchimp. No Typeform. No Mixpanel.
Just PostgreSQL.
