Web Development Services for Websites, Platforms and Applications
Web development services cover designing, building and running websites and web applications. Ours combine front-end engineering, application architecture, APIs, integrations, content platforms, performance, accessibility, security and search requirements in one delivery model.
A website is usually content- and publishing-oriented. A web application usually includes interactive workflows, authenticated users, permissions, application logic, transactional data, APIs or integrations. Enterprise platforms often combine both.
The distinction matters because architecture, testing, performance, security, deployment, observability and maintenance needs can be very different, even when both run in a browser.
Custom web application development: what we build
Enterprise web development
We build content-led enterprise sites for teams that need governance and reusable components. These sites also have to be fast, accessible and visible in search, connect to other systems and give editors a publishing workflow they can rely on.
Custom Web Application Development for Business Workflows
Our web app development services cover secure portals, dashboards, workflow applications, self-service platforms, authenticated B2B products, internal tools and browser-based business software.
Web Portal Development for Customers and Partners
Our web portal development services cover role-based experiences for customers, partners, suppliers, members and other external users who need access to data, workflows, documents or transactions.
Headless CMS and Composable Web Development
In a decoupled architecture, content, commerce, applications and services change on their own schedules but share one consistent experience layer. For headless commerce, see our ecommerce development company practice.
Multi-Brand and Multi-Locale Web Development
Organizations that operate across brands, regions, languages or business units get one shared platform architecture instead of a duplicated codebase for each.
CMS Development and Content Publishing Workflows
We design the publishing system around how your marketing and editorial teams work: components, workflows, governance, previews, permissions, structured content and integrations. For a worked example, see how to build a Laravel blog with Filament.
Web application development services built for production
Portals, dashboards and authenticated B2B products carry more risk than a marketing site. Users sign in, data changes hands and the application connects to the systems you already run. Our custom web application development services plan for that from the first architecture session.
The first decisions are about who gets in and where data lives: authentication and role-based access, API and backend architecture, database and data-flow design, and the third-party and internal system integrations. Security boundaries are set at the same time.
Every production web application we build also gets:
- Caching and performance work
- Logging and observability
- Automated testing, CI/CD and deployment
- Accessibility where applicable
- SEO and rendering requirements where public content is exposed
For integration-heavy applications, see our API integration services. For internal business workflows, see our work as a custom software development company.
Custom Web Application Development Services: Release Acceptance and Handover
For authenticated portals and workflow applications, our custom web application development services include release checks beyond how a page looks. We verify important user roles, permission boundaries, external API failure handling, business-critical transactions and the monitoring needed to diagnose incidents. The handover identifies deployment owners, rollback steps and the documentation the receiving team needs to support the application.
Web Performance Optimization, Accessibility and Technical SEO
Performance and accessibility should be engineered into the platform from the start instead of patched in during a final audit. Public content also needs rendering, metadata, URL, internal-link, canonical, sitemap and technical SEO decisions that work with the application architecture. Our guide to SEO for developers covers those decisions in more detail.
When UX and expert-user workflows are central to the platform, the team behind the UI UX design services works on it too.
Technical SEO for Website Launch and Migration (Add-On)
Public pages need crawlable rendering, metadata, URL conventions, internal links, canonical tags and sitemaps that fit the application architecture. We make those decisions during the build. For a migration, we also plan redirect mappings and post-launch Search Console checks. If the project needs a deeper audit, AI search visibility measurement or ongoing optimization, our technical SEO services are available as an add-on.
Website Migration and Replatforming Services
A migration involves more than moving pages. It can include URL inventories and redirects, content models, permissions, integrations, analytics, technical SEO, data migration, deployment, testing and staged cutover. For URL changes, we map relevant old pages to new destinations and check redirects, canonicals, internal links and sitemaps. Rankings can fluctuate after substantial changes, so we plan monitoring and validation instead of promising unchanged traffic.
Keep
The behavior that matters
Remove
Duplicated or fragile architecture
The safest approach is to inventory what the current platform actually does before replacing it. Then we keep the behavior that matters and remove the duplicated or fragile architecture.
Web Application Security, Cloud Hosting and Operations
Production web applications need an operating model for deployment, monitoring, incidents, access, secrets, backups, dependencies and change. The right setup depends on the product, traffic, compliance requirements, existing cloud environment and team ownership.
Every web build
CI/CD pipelines and deployment automation are part of every web build. For infrastructure and operations beyond the web layer, see our DevOps consulting services, and for security-sensitive requirements, read our security posture.
Enterprise Web Development Challenges at Scale
Web platforms get expensive when publishing depends on engineering, every region runs a separate stack, integrations are fragile, authentication is inconsistent, performance degrades, or a simple brand change means rebuilding several platforms.
The architecture has to support the people publishing content, the users completing workflows, the systems exchanging data and the team operating the platform after launch.
When custom web development pays off
A template or hosted site builder is often enough. If the site is mostly marketing content for one brand, has few integrations, and the platform's publishing tools already suit your team, a custom build may cost more than it returns.
Custom web development services pay off when:
publishing depends on a developer every time
every region or brand has ended up on its own platform
integrations with ERP, CRM, identity or payments break when either side changes
performance degrades when traffic arrives
users need authenticated workflows, portals or transactions that a template can't model
In those cases, the long-term cost of workarounds may exceed a purpose-built platform. During discovery, we compare those costs and explain whether a custom build is justified.
Web Development Case Studies: Enterprise Websites and Applications
Chicago Detours (Travel & tourism)
We rebuilt the website with enhanced listings, virtual tours and a booking system. The published case study reports traffic up 45%, conversion rate up 40% and virtual tour bookings up 30%.

Discovery (1–2 weeks)
We learn who the users are and how publishing and application workflows run today. We also map the content, integrations, analytics and infrastructure, the performance and accessibility requirements, and any migration constraints.
Architecture (2–3 weeks)
This is where we decide the rendering strategy, content architecture and application boundaries, along with APIs, identity, data, integrations, hosting, caching, observability and security.
Design and prototyping
Designers work out reusable patterns, information architecture, interaction behavior, responsive states and accessibility requirements.
Engineering
We build components, application logic, APIs, integrations, CMS workflows, tests and deployment automation in two-week increments.
Migration and validation
After content and data move over, we check redirects, analytics, forms, permissions, integrations, performance, accessibility and the critical user journeys.
Launch and iteration
The platform goes live with monitoring, named owners, documentation, support procedures and a roadmap for ongoing improvements.

Frequently asked questions
Web Development Cost: Scope, Integrations and Migration
What we ask
The first question is scope: one site, or a shared platform for many brands and locales. The second is what runs it today. That could be a headless CMS, WordPress or Drupal, an enterprise DXP such as AEM or Sitecore, a hand-built site, or nothing yet.
ERP, CRM, identity, payments and internal systems each add design and testing work. Authenticated workflows like portals, dashboards and transactions cost more than content pages.
What we price in
We also price in:
- the content model and publishing setup: how many people publish, and what governance, previews and permissions they need
- migration scope (content, data, URL mapping and redirects)
- the standards to meet, such as WCAG 2.2 AA, VPAT or Section 508, GDPR or data residency, and your performance targets
Fixed-scope work is priced by milestone, engineering pods monthly and managed engineering annually. Send your scope through the web development estimator and you get a range back within one business day.

Enterprise Web Development for Platforms Built to Evolve
On a well-built enterprise platform, publishing gets easier and application workflows get safer. Integrations are clearer and performance is something you can measure. A maintainable architecture can reduce the effort of future changes compared with a fragile or duplicated system, though the outcome depends on the existing platform and the work involved.
