Details
How I work

From first call to launch, no black box

A clear, predictable path. You see the proposal, the weekly progress, and the moment it goes live. No mystery timelines, no status theater.

01

A clear proposal, not a 40-page contract

Within 48 hours of the first call you get fixed scope, fixed price, and a launch date in plain language. You know exactly what you are getting before I start.

01Scope: marketing site, 8 pages, CMS
02Fixed price: $7,999
03Timeline: 3 weeks to launch
04Warranty: 1 year on every bug
02

You see working software every Friday

I build in short cycles with weekly demos. Real progress you can see on a preview link, not status reports. You give feedback as it takes shape, no black-box delivery.

It goes live, and it works

Tested, reviewed, and live with monitoring in place. If it goes live, it works. In 17 years I have never missed a launch or ghosted a customer, and post-launch fixes are free.

Not sure which service you need?

Common questions about choosing the right engagement model.

If you need a corporate site, landing page, or marketing website, choose Websites. If you have an existing app that needs ongoing development or need a custom internal tool built from scratch, choose Applications. If you want AI features built into your product, like answers pulled from your own data or an agent that takes real actions, choose AI Development. If your problem is HubSpot data arriving raw, duplicated, or not arriving at all, choose HubSpot Integrations. Not sure? Let's talk and I'll tell you honestly.

Yes. I work with customers across the US, UK, EU, and Latin America. All contracts use clean B2B invoicing for simplified billing and tax compliance.

I take on one customer at a time. If I have an opening, I can usually start within 1-2 weeks of signing. Fill out the contact form and I'll let you know my current availability.

Applications is a monthly subscription for ongoing product development. HubSpot Integrations is scope-based work on a specific problem: getting data from your other systems into HubSpot, clean and mapped correctly. If HubSpot is already in place and the data reaching it is unusable, that is the integration service. If you need a product built or maintained over time, that is Applications.

That's common. Many projects combine a website redesign with a custom CMS, or an app with AI features. Let's talk and I'll scope exactly what's needed and recommend the right model.
