Approach

Not another template website.

Two paths lead to a live website. Only one starts with your business. Hover a stage on either side to see what happens.

Template approach
  1. 1Theme

    Pick a marketplace theme. Your layout, structure and content model are already decided.

  2. 2Plugins

    Bolt on plugins for anything the theme can't do. Every plugin adds a dependency.

  3. 3Compromise

    Business processes get bent to fit the theme's assumptions. Custom edits become fragile.

  4. 4Result

    A site that mostly works, until your workflow, integration or scale hits the theme's ceiling.

Custom approach
  1. 1Requirements

    We start with what your business, team and customers actually need to accomplish.

  2. 2UX architecture

    Journeys, information architecture and data model — modelled to your real work.

  3. 3Technical architecture

    Frontend, backend, APIs, integrations and infrastructure chosen for the job.

  4. 4Custom platform

    A system you own, extend and evolve — engineered around your business, not a theme.

Different businesses · different systems

Six examples. Six different architectures.

Concept architectures showing how the same discipline — requirements first, then engineering — produces very different systems.

What we can build

Pick a system. See what's inside.

Business Websites

Marketing site with programmatic pages and structured content.

Typical functionality
  • Pages CMS
  • Blog
  • Case studies
  • Forms → CRM
Common architecture
Next.jsHeadless CMSCRM

From business logic to digital system

Requirements first. Technology second.

  1. 01Business

    What does the business actually need?

    Revenue model, workflows, pressure points. Understood before any technology decision.

  2. 02Users

    Who uses this and what do they need to accomplish?

    Personas, journeys, edge cases. Every screen answers a real user goal.

  3. 03Experience

    Information architecture, journeys, wireframes.

    Structure first. Visual polish later. This is where projects usually go wrong.

  4. 04System

    Frontend, backend, database, APIs.

    Chosen for the job — not because a technology is trending on Twitter.

  5. 05Integrations

    CRM, payments, WhatsApp, email, ERP, AI.

    Modelled as first-class citizens, not last-minute bolt-ons.

  6. 06Deployment

    Testing, security, performance, monitoring.

    A launch is a checkpoint, not a finish line. Observability from day one.

Reference architecture

One system. Many moving parts.

A typical custom stack. Every project uses a subset — not the whole thing.

Trademarks belong to their respective owners. Listed as tools we work with, not partnerships.

Integrations

Your website doesn't have to live alone.

Custom sites become the connective tissue between your CRM, payments, messaging, analytics and AI systems.

Frontend engineering

A component system, not a stack of pages.

Every custom project ships a design system. Reused everywhere, themed once, accessible by default.

Backend & business logic

Example: a custom quote system.

This is what "custom development" actually looks like under the hood — logic, integrations, side-effects and state.

  1. 1
    Visitor submits requirement

    Multi-step form validated in the browser and again on the server.

  2. 2
    Server validation

    Business rules run — allowed regions, blocked domains, spam heuristics.

  3. 3
    Pricing engine

    Custom pricing rules by product, quantity, tier and geography.

  4. 4
    CRM record

    Enquiry, contact and opportunity created via CRM API — idempotently.

  5. 5
    Salesperson assigned

    Round-robin or territory rules with fallbacks.

  6. 6
    WhatsApp acknowledgement

    Templated message sent through provider API.

  7. 7
    Email notifications

    Team + customer emails via transactional provider.

  8. 8
    Dashboard updated

    Realtime pipeline updates so sales sees it before the customer refreshes.

APIs & integrations

Data has to move to be useful.

WebsiteCRM

Enquiries, contacts, deals

WebsitePayments

Charges, invoices, subscriptions

WebsiteERP

Inventory, orders, shipments

WebsiteWhatsApp

Notifications, templates, inbox

WebsiteAI

Assistants, embeddings, generation

WebsiteAnalytics

Events, funnels, revenue

Do you actually need custom development?

A quick, honest check.

Signals selected · 0/6

A CMS or standard website is probably enough.

If nothing above sounds like you, a well-configured CMS or template will get you live faster and cheaper. That's a good outcome.

Talk about it

Performance engineering

Fast is a decision at every hop.

Hop 1
Request

TLS, edge routing, request coalescing

Hop 2
Server

SSR/ISR/RSC, streaming HTML

Hop 3
Data

Indexed queries, query planners, caching

Hop 4
Render

Code-split JS, lazy hydration

Hop 5
Browser

Preloaded fonts, prioritised LCP, deferred JS

LCP

Largest Contentful Paint — prioritise the hero

CLS

Cumulative Layout Shift — reserve space, avoid jumps

INP

Interaction to Next Paint — keep the main thread free

Real numbers depend on scope, hosting and content. We measure per project instead of promising scores.

Security & reliability

Security is layers — not a checkbox.

  1. L1
    User

    Session hygiene, MFA where sensitive

  2. L2
    Authentication

    Managed providers, short-lived tokens

  3. L3
    Authorization

    Row-level rules — not client-side hiding

  4. L4
    Validation

    Zod / schema checks server and client

  5. L5
    API security

    Rate limits, CSRF, signed webhooks

  6. L6
    Database

    Least privilege, encrypted at rest

  7. L7
    Monitoring

    Alerts on anomaly, audit trail

No serious builder claims "100% secure." We claim a defensible baseline and continuous review.

Scalability

Built to evolve. Not to be rebuilt every 18 months.

Launch

Small audience, focused surface

Stage 1
Growth

Traffic climbs; caching and CDN start earning their keep

Stage 2
Expansion

More content, more pages, structured taxonomy pays off

Stage 3
Integration

CRM, ERP, AI wire into the platform as first-class parts

Stage 4
Platform

New surfaces — apps, kiosks, partner portals — share the backend

Stage 5
Scale

Multiple markets, locations, languages; the architecture holds

Stage 6

Development process

Twelve stages. No mystery.

Stage 01

Business discovery

Understand goals, constraints, budget, timeline and the humans on both sides.

FAQ

Custom development questions.

Designing and engineering a website around your specific business, users, workflows and integrations — instead of adapting a theme or template. Everything from the data model to the admin experience is a decision made for you.
When your workflow is unusual, integrations are meaningful, performance and SEO matter, or you expect the product to grow beyond what a CMS can handle without heavy plugin gymnastics.
WordPress is excellent for content-first sites with mostly standard needs. Custom wins when the site is a product surface — logic, integrations, dashboards, unusual data, scale.
A focused custom marketing site is 4–8 weeks. Portals and SaaS foundations run 8–16 weeks to a strong first version. Scope drives it — not the calendar.
By scope, not page count. Screens, custom logic, integrations, roles, data complexity, migration and testing all move the number. You'll see the breakdown before we start.
Yes. We ship either a purpose-built admin or a headless CMS (Sanity, Contentful, Payload, Directus) modelled to your content — not a generic page builder.
Almost anything with an API. Common: CRM, ERP, payments, WhatsApp, email, calendars, analytics, AI. Legacy systems usually need a small adapter service.
Yes. Content, users, URLs and SEO signals migrate on a plan — with 301 mapping, canonical strategy and staged cut-over so rankings don't drop.
You do. Repos transfer to you. No lock-in, no proprietary editor, no hosting hostage situations.
That's the point. Custom platforms are built to evolve — new modules, integrations, surfaces and languages ship without rebuilding the base.
Semantic HTML, SSR/ISR, structured data, sitemaps, canonicals, internal linking, Core Web Vitals and content architecture — designed in, not bolted on.
Managed auth, row-level authorization, server-side validation, rate limits, signed webhooks, least-privilege database roles, encrypted secrets and monitoring.
