DEV404makes digital workhold up.

Design. Engineer. Validate. Digital systems with enough judgement to work after launch.

[ About Dev404 ]

Structurebefore surface.

We are a digital architecture and design studio blending code, design and AI workflows.

We build modern systems for founder-led organisations, NGOs, service businesses and agencies that need sharper presentation, better structure and a cleaner path from idea to launch.

Services / 04 disciplines

One studio,connected work.

Strategy, visual direction and engineering are shaped together so the finished system does not lose the thinking that made it strong.

[ Method preview ]

Design.Engineer.Validate.

Every phase should produce a decision, an artefact or a risk removed.

The homepage shows the rhythm. The Method page opens up the full six-stage delivery system.

01

Frame the right problem

DESIGN

We turn context, audience needs and constraints into one clear direction before expensive build decisions are made.

Decision

What deserves to be built, for whom, and in what order.

Leaves with

A shaped brief, system map and responsive visual direction.

02

Build the system

ENGINEER

Approved intent becomes a maintainable production build with reusable components, integrations and deliberate interaction behaviour.

Decision

Which technical structure will hold the experience together.

Leaves with

A responsive, accessible and maintainable production system.

Prove it holds up

VALIDATE

We test the real experience across viewports, content states, performance conditions and the practical details that affect launch confidence.

Decision

Whether the work is ready to launch and hand over with confidence.

Leaves with

A verified release, QA record and clear ownership path.

[ Engagements ]

Clear waysto begin.

These are starting points. The right lane depends on how clear the scope is, how much shaping remains and what the finished system needs to carry.

01

From R2,500

FOCUSED

Best for

Contained scopes with one clear outcome

For focused fixes, starter pages, audits, or a small public presence that needs to look credible quickly.

  • Single page or section-level improvement
  • Responsive layout clean-up
  • Basic copy and structure pass
  • Launch or handover notes
02

R8,500 to R12,500

COMPREHENSIVE

Best for

Multi-section or multi-page business websites

For sharper business websites, richer presentation, and a more complete design-to-build experience.

  • Premium multi-section or multi-page build
  • Custom visual direction
  • Performance and responsive QA
  • Launch-ready polish and handover
03

[ Custom scope ]

SYSTEMS

Best for

Operational platforms and technical stewardship

For teams requiring dedicated scale, embedded engineering and direction.

  • Dedicated planning and architecture
  • Workflow and system design
  • Senior technical direction
  • QA, documentation and handover

[ The Dev404 difference ]

WhyDev404.

The difference is not another layer of decoration. It is how the decisions are made, tested and left in your hands.

Systems workshop / judgement before executionD404

01

Technical judgement

Design decisions are tested against the system that must carry them, not separated from implementation reality.

02

Research before execution

We isolate the real pressure behind the brief before committing time and budget to a surface treatment.

03

Validation in real conditions

Responsive fit, content states, performance and launch risks are reviewed as part of the work, not left for later.

04

Built for handover

The finished system leaves with clearer ownership, reusable decisions and a practical path beyond launch.
