Shipping products, not prototypes

Ideas to deployed SaaS.
Day one.

Full-stack product engineering. I own the entire arc — from validating whether something should exist, to shipping a working product with auth, billing, and multi-tenancy baked in.

What I refuse to skip.

Every product ships with these baked in. Not bolted on later. Not in the next sprint. In the first commit.

01

Auth & billing from commit one

These are load-bearing walls, not furniture. Signup, login, Stripe integration, and tenant isolation are foundational — not features.

02

Data model first

Migration files before application code. The schema is the product; the UI is a view of it. Get the data right and everything else follows.

03

Operational sanity

Boring, well-understood infrastructure. Managed services over self-hosted. Convention over configuration. If you can't run it, I won't build it.

04

Multi-tenancy from the start

SaaS means shared infrastructure serving isolated customers. Data isolation and tenant-scoped access are architecture decisions, not feature tickets.

05

Security as structure

No plaintext passwords. No hardcoded secrets. No disabled CORS for convenience. Not even in prototypes. Especially in prototypes.

06

User-facing completeness

A product isn't shipped until it has signup, login, billing, a settings page, and error handling that doesn't show stack traces to customers.

Boring technology,
exciting products.

I default to proven tools unless there's a concrete reason not to. The stack serves the product, never the other way around.

🐘

PostgreSQL

The database. Row-level security, JSONB when needed, rock-solid at any scale.

Next.js / Remix

Server-rendered, edge-ready. Pick based on the product's routing needs.

💳

Stripe

Billing is a solved problem. Subscriptions, metered usage, invoicing — out of the box.

🔷

TypeScript

End-to-end type safety. Shared types from database to API to frontend.

🔒

Caddy

Auto-TLS, zero-config HTTPS. One binary, no certificate management.

🐳

Docker

Identical environments from laptop to production. No "works on my machine."

From zero to
taking payments.

Not a 12-week engagement. A focused sprint from idea validation to deployed product.

01

Validate the problem

Who's the user? What's the pain? Is this a vitamin or a painkiller? I don't write code until these have clear answers. If the answer is "build me a SaaS" with no further context, I ask questions first.

Day 1
02

Design the data model

Schema first. Migration files before application code. Multi-tenancy, access patterns, and relationships defined at the database level. The data model IS the product.

Day 1–2
03

Build the core loop

Auth, the primary user action, and billing. Not a landing page with a waitlist — the actual product. Users can sign up, do the thing, and pay for it.

Day 2–5
04

Ship to production

Deploy, configure DNS, set up monitoring, handle edge cases in error states. A real product at a real URL taking real users and real money.

Day 5–7

Ready to ship something?

Bring the idea. I'll bring the infrastructure.
