Platforms & approaches

i.

Replatforming & migration

Move off legacy systems without losing SEO equity, order history or a single day of sales. Phased cutovers, data validation and rollback plans included.

ii.

Headless & composable architecture

Decoupled front ends with best-of-breed services for search, content, pricing and checkout, so each piece can evolve independently.

iii.

Peak-ready performance

Load testing, edge caching and auto-scaling engineered so flash sales and holiday traffic feel like any other Tuesday.

iv.

Back-office integration

ERP, PIM, OMS, WMS, tax, payments and shipping connected through resilient APIs and event-driven pipelines.

v.

Conversion optimisation

Analytics instrumentation, experimentation frameworks and UX iteration focused squarely on average order value and conversion rate.

How we deliver

A delivery model built for predictability.

Large programs fail on ambiguity, not code. Our process front-loads the hard decisions, gives you visibility every week, and ties milestones to outcomes you can measure.

01

Discovery

Stakeholder workshops, technical audit, requirements and success metrics.

2–6 weeks
02

Architecture

Solution design, security model, roadmap, estimates and a fixed delivery plan.

2–4 weeks
03

Build

Agile sprints with demos every two weeks, automated testing and code reviews.

Iterative
04

Launch

Load testing, security sign-off, staged rollout and hypercare support.

Zero-downtime
05

Operate

24/7 monitoring, SLAs, maintenance and a roadmap for continuous growth.

Security & data

Your customers' data, treated like our own.

Security isn't a phase at the end of a project. It's built into how we architect, write, review, deploy and operate every system we touch.

FAQ

Questions we hear often.

What size of project do you take on?

We focus on substantial, enterprise-grade initiatives. Most of our engagements are in the range of $500,000 and above, typically spanning several months to multiple years across design, build and ongoing support.

Can you take over an existing system built by another vendor?

Yes. We start with a structured technical audit covering code quality, security, infrastructure and documentation, then present a stabilisation plan before taking over operations.

Who owns the code and intellectual property?

You do. All source code, designs, infrastructure configuration and documentation produced for your project are transferred to you under the contract.

How do you handle confidentiality?

We sign mutual NDAs before any detailed discussion, and our teams follow strict access-control and data-handling policies throughout the engagement.

Do you provide support after launch?

Every launch includes a hypercare period. Beyond that, our managed services offer 24/7 monitoring, incident response, maintenance and continuous improvement under defined SLAs.

How quickly can a project start?

Discovery can typically begin within two to four weeks of signing, with the full delivery team ramped up once architecture and scope are agreed.
