Shopify storefronts built to convert, not just to look good

Custom themes, storefront apps, and performance work from a developer who's shipped behind 100+ stores.

I'm Cesar Ayala. I build custom Shopify themes, storefront apps, and stores tuned for speed and sales — for merchants and brands who've outgrown a stock theme. I shipped this exact work behind 100+ stores at a New York Shopify agency, and I serve US clients on your timezone, at senior level, without a US-agency invoice.

What you get

  • A custom Liquid theme tailored to your brand, not a reskinned template
  • Conversion-focused product, collection, and cart pages that lift add-to-carts
  • Custom storefront sections and apps for logic a theme can't express
  • Speed work: faster load times that quietly recover lost sales
  • A disciplined app stack — audited and pruned, not bloated with monthly fees
  • Clean WooCommerce or Magento migrations that keep your SEO intact

FAQ

What does a custom Shopify project cost?
Theme customization runs about $1,000–$9,000; a fully custom build with bespoke logic runs $7,500–$30,000+. Most merchants need theme work, not a custom build — I'll tell you straight which one you actually need before you spend.
How long does it take?
Theme customization takes 3–6 weeks. A fully custom build runs 6–12 weeks from kickoff to launch. Migrations add time on top, mostly for the theme rebuild and SEO preservation — not the data move itself.
How do we work together, and what about timezone?
I start with where you are — revenue, catalog, what's actually slowing down sales — then scope the smallest build that moves the number. I serve clients in Mexico and the US, so US merchants get same-timezone, hands-on collaboration throughout.
Why work with you instead of an agency?
You get the senior developer who's shipped 100+ stores doing the actual work, not a junior behind an account manager — at a rate that isn't padded with US-agency overhead. And I'll talk you out of spend that won't move your conversion rate.
