Case study

Building with Auto Trader’s engineering teams

Public website work, internal web applications, and a delivery model built around partnership with in-house engineers—not a handoff over the wall.

Overview

A partner inside the engineering organisation

Auto Trader needed more than an agency that ships pages and walks away. The brief covered the public website and internal web apps—delivered alongside their engineers so quality, ownership, and velocity stayed high across the programme.

The challenge

Public site and internal tools, one delivery standard

Marketplace platforms live or die on trust and speed. The work had to serve customers on the public website while also giving internal teams sharper tools—without creating two different ways of building software.

Customer-facing website

A high-traffic automotive marketplace where clarity, performance, and reliability are non-negotiable.

Internal web apps

Tools for the people who operate the business—workflows that need to be fast, clear, and dependable.

Engineering partnership

Delivery had to fit how Auto Trader’s engineers already work—shared standards, shared ownership, no black-box handoffs.

What we delivered

How we worked with their engineers

We embedded into the delivery rhythm—shipping website and internal product work while collaborating directly with Auto Trader’s engineering teams.

Website delivery

Product and engineering work on the customer-facing website—focused on experience quality, performance, and maintainable front-end delivery.

  • Customer-facing website delivery
  • Experience and performance focus
  • Maintainable front-end foundations

Internal web applications

Internal tools built for real operational workflows—so teams can move faster with less friction between systems.

  • Apps shaped around internal workflows
  • Clear interfaces for day-to-day operators
  • Built to sit alongside existing systems

Engineering collaboration

We worked with Auto Trader’s engineers as partners—aligned on standards, reviews, and delivery so the work stayed owned by the organisation.

  • Paired delivery with in-house engineers
  • Shared reviews and quality bar
  • Knowledge transfer built into the process

Reliable delivery

Clear scopes, steady shipping, and communication that kept product and engineering aligned as priorities evolved.

  • Phased delivery with clear checkpoints
  • Transparent progress and trade-offs
  • Partnership that scales with the roadmap
Outcomes

Digital products owned by the teams who run them

The engagement left Auto Trader with stronger website and internal product delivery—and a working model where Acculogics and in-house engineers shipped as one team.

Public website

Delivery on the public website with a focus on quality and maintainability.

Internal apps

Web applications built for the teams operating the platform every day.

Shared engineering

Close collaboration with Auto Trader engineers—not a siloed vendor model.

Sustainable delivery

Work that the organisation can own, extend, and improve after each release.

Client voice

What the client said

How the partnership felt from the client’s side, from collaboration and delivery through to the result.

Acculogics worked as an extension of our engineering team. They helped deliver our website and internal web apps with the same care we expect in-house—collaborating closely with our engineers, communicating clearly, and shipping work we could trust in production.
