Ecommerce EngineeringEcommerce that holds together

Shopify engineering for busy trading and complex catalogues. Architecture first, controlled releases and performance budgets agreed up front.Shopify builds and rebuilds for catalogues with real complexity. Structure, performance, navigation, filtering and the conversion work that follows.

We are not consultants describing this from the outside. We run three businesses of our own and do every one of these jobs in them, every week.

Delivery ApproachHow We Deliver

We diagnose constraints, rebuild the parts that create instability and ship improvements in controlled increments. The goal is a store that stays fast, editable and dependable as the catalogue grows.We look at what is causing problems, fix the most important things first and keep improving. The goal is a store that stays fast and easy to manage as you grow.

"Success looks like: A store that meets agreed performance targets and allows your marketing team to build landing pages without engineering support.A store that loads fast, stays reliable and lets your team update content without needing a developer."

Common Questions

Q.Do you use pre-bought themes?

No. We engineer bespoke themes. Off-the-shelf themes can introduce avoidable constraints at scale.

Q.How long does a build take?

Typical replatforming projects take 12-16 weeks. Optimisation sprints are 2 weeks.

Q.Do you handle the design?

We partner with your internal design team or specialist brand agencies. We focus on the engineering rigour.

Q.What about data migration?

We script the full migration of customers, orders and products using the Admin API.

Q.Do you support Headless?

Yes, but only when necessary for complex internationalisation or CMS requirements.

Q.How do you handle SEO during migration?

We map every legacy URL and enforce 301 redirects to preserve domain authority.

Some fixes show impact in weeks. Structural work compounds over time depending on catalogue size and competition.
