Storefronts that convert, for independent brands
Faster pages,a clearer checkout.
I check what slows the product page and where checkout becomes hard to use, then fix the parts that matter. Delta Xi shows a storefront I built, including payments and product recommendations. Changes to sales need to be measured against your own starting point.

What actually slows independent e-commerce brands
Rent on a checkout you cannot change
Platform fees scale with your revenue whether or not the platform did anything to earn it, and the checkout is the one page you are least allowed to touch. That is the page the whole business converts on.
A dozen apps doing one job each
Reviews, subscriptions, affiliates, support, analytics. Each is a subscription, a script tag and a slower page, and no two of them agree on what a customer is.
Nobody in the building can change anything
Every copy tweak becomes a ticket to an agency who bill by the hour and get to it next week. The people who know what needs to change are the people who cannot change it.
websites that convert
Server rendered, fast on a phone when the signal is poor, and built so the people who know what needs changing can change it without raising a ticket. Search, payments, booking and a CMS come built in, not bolted on eighteen months later by somebody else.
- Fast on a bad phone, measured
- Load time is checked on a throttled connection. A laptop plugged into fibre tells you nothing about the customer on a train. What slows a site down is almost always the scripts that have to finish before anything is allowed to appear.
- Edited by whoever writes the copy
- The person who knows the price has gone up changes the price. No ticket, no agency, no waiting until next week to correct a typo on the page that sells for you.
- The next step on the page
- Booking, enquiry or checkout happens where the reader already is. A phone number at the bottom of a brochure asks them to start again somewhere else, which is where most of them stop.

- 01Before code
Scope
One call, then a written spec. What it does, what it deliberately does not do, and what milestone one is. You sign that off before I write a line.
- 02Early
First deploy
A narrow slice that actually works, running where it belongs. A URL you can open, a build on your phone, a job on your own servers. Real data, real hosting, no placeholder screens.
- 03Ongoing
Build in the open
Deploys land as the thing fills in, not in one drop at the end. You watch it happen. And you get to change your mind while changing it is still cheap.
- 04Handover
Yours to run
The product runs in your accounts, with the domain, hosting and documentation under your control. Source-code transfer is quoted separately; we agree what is included during scoping.

I got my hands on a computer at 6 and never really stopped.
Now it is decentralised finance, tokenising real-world assets and topological deep learning, then building whatever those turn into. Continuum came out of that. So did Delta Xi (δξ, an infinitesimal change in a random variable).
Bossa nova and MPB were always on at home, so I sang before I played anything. Guitar and piano came later, then jazz.

Have an idea? Tell me.
Need the audience too?
I can build the thing. Getting people to notice it is a separate job, and not mine. For that I work with Nytforge, who film, edit and put the work in front of a local audience. They are strongest with automotive and local businesses.
