How we'll work together

Most freelance projects fail not because of bad code, but because of fuzzy scope and silent timelines. Here's how I run engagements so that doesn't happen.

01

Discovery call

Free · 20 minutes

We jump on a call so I can understand your business, what you're trying to build, and what success looks like. By the end, we'll both know whether I'm the right fit. No pressure, no sales pitch — if your project isn't a fit, I'll tell you and point you toward someone who is.

You walk away witha clear sense of scope, ballpark pricing, and a realistic timeline.

02

Scope & proposal

2–3 days · $0

I send a written scope document covering exactly what gets built, what's out of scope, the timeline, the price, and the payment schedule. We iterate until you're confident in the plan.

You walk away witha signed proposal you understand and trust.

03

Build & weekly demos

2–10 weeks · 50% upfront

I start building. Every week, you get a Loom walkthrough of progress and a live staging link to click through it yourself. If priorities shift mid-build, we adjust through written change requests.

You walk away withweekly visible progress, working software you can use, and zero "what's happening?" anxiety.

04

Launch & handoff

1 week · final 50% on launch

We deploy to production on your infrastructure (you own the code from day one). Documentation, architecture walkthrough, and 2 weeks of post-launch support included.

You walk away witha live product, full code ownership, documentation, and a developer who'll still pick up the phone after the invoice clears.

The stack I build with

Tools chosen deliberately, not collected accidentally. Every project uses the same battle-tested core — so what I ship is fast to build, easy to maintain, and won't break six months after launch.

Frequently asked questions

Let's build something that ships.

Pick a 20-minute slot on the calendar, or send the project details straight through the form — whichever feels easier. I read every inquiry myself and reply within one business day.
