Stores built
to sell and scale.

Builds, theme development, migrations and a tech stack that scales - from zero-to-one launches to re-platforming an established store onto something faster.

Start your build

In short

A Shopify development expert builds, customises or migrates your store so it loads fast, is easy to manage and is set up to convert. I'm Vishal Pothur, and I handle zero-to-one builds, custom theme work, migrations and app stack cleanup for D2C brands, with SEO, tracking and CRO planned in from the start.

Overview

Conversion-focused ecommerce, engineered.

A great Shopify store is fast, clear and built around conversion from day one - not a pretty template that buckles under traffic.

I handle development, theme customization, migrations and the app stack, balancing design, speed and CRO so the store performs as well as it looks.

FAQ

Shopify development questions, answered.

Can you launch a brand-new store? +
Yes - from product strategy and architecture to a launched, conversion-led store, as with Divya Hair Paris.
Can you fix or speed up my current store? +
Yes. Most speed problems come from heavy themes and unused apps. Removing app bloat, replacing apps with lightweight custom sections and moving to a faster theme are often the biggest wins. On Singhania's, this made the mobile site about two seconds faster.
Do you handle the marketing too? +
Yes - the store and the growth engine are connected, which is the whole point of working with one operator.

Need a store built to convert?

Let's build (or rebuild) your Shopify store the right way.

What should a Shopify store have in place before launch?

Before launch, a Shopify store should have a clean product and collection structure, a fast mobile theme, tested payments and shipping rules, working purchase tracking, basic SEO and schema, and clear policy pages. Skipping any of these usually means paying for rework once ads are running and real orders come in.

  • Product data set up once: variants, options and metafields that keep filters and product pages consistent
  • Collections mapped to how buyers search, rather than how stock is grouped
  • Payments, shipping zones, taxes and COD rules tested with real orders
  • GA4 and Meta purchase events checked against test orders
  • Titles, URL handles, product schema, redirects and sitemap ready for Google
  • Policy pages, contact details and a WhatsApp or support path easy to find

This is the pre-launch list I run through on every build:

Should you use a ready-made theme or a custom Shopify theme?

Most new D2C brands should start on a well-built theme from the Shopify Theme Store and customise its sections rather than commission a fully custom theme. Go custom when your products need layouts or logic the theme can't handle, or when the theme is already slowing the store and capping conversion.

A fully custom theme isn't automatically better. It costs more up front, it depends on whoever wrote the code, and it misses the updates a maintained theme gets for free. The middle path usually works best: keep a solid Online Store 2.0 theme as the base and build custom sections only where the brand needs them, such as bundle builders, size guides or comparison blocks.

Whichever route you take, the theme editor should stay usable. Your team ought to be able to change banners, reorder sections and launch a sale page without raising a developer ticket.
