Who This Is For

Built for businesses that need more than a website

  • Companies whose customers, vendors, or partners need to log in and get things done.
  • Teams replacing spreadsheets and email with a web application people can use from anywhere.
  • Businesses with an existing web app that is slow, hard to maintain, or impossible to extend.
  • Organizations that need accessibility, security, and performance requirements met, not promised.

What We Build

Web applications that do work

Customer and partner portals

Accounts, requests, documents, status, payments, and messaging connected to your back office.

Dashboards and internal apps

Operational views and workflows for teams, with roles, approvals, and audit trails.

Enterprise web applications

Multi-role systems with SSO, permissions, integrations, and the reliability a business depends on.

AI features

Assistants, search over documents, document upload with extraction, and automated drafting built into the interface.

Performance and accessibility

Fast loads, Core Web Vitals within targets, and accessible interfaces that meet WCAG expectations.

Marketing sites with substance

Fast, structured, SEO-ready company sites on a static or Next.js stack, built the way this site is built.

Applications, not just pages

A web application is where customers, partners, and teams get things done: request, upload, approve, pay, check status. It has to be fast, accessible, secure, and connected to the systems behind it. DPI builds those applications on React, Next.js, Node.js, and PostgreSQL, with AI features where they help users, and with performance and accessibility measured on every release.

What we build

Customer and partner portals, dashboards and internal applications, multi-role enterprise systems with SSO and audit trails, AI features such as document upload with extraction and assistants over documents, and company websites built for speed and search.

How we work

Discovery and prototypes before the build, architecture designed for your load and compliance, increments every few weeks with automated tests, and launch with monitoring and pipelines. You own the code; your team or DPI operates it.

What you measure

Task completion and adoption, load times and Core Web Vitals, support requests avoided, and the business outcomes the application enables, reviewed at every release.

How It Works

How we deliver web applications

  1. Discovery and design

    Users, roles, workflows, integrations, and constraints defined; interfaces prototyped and reviewed.

  2. Architecture

    Frontend, API, data model, authentication, security, and hosting designed for the load and the compliance you need.

  3. Build in increments

    Releases every few weeks with real users, automated tests, and performance and accessibility checks.

  4. Launch and operate

    Monitoring, logging, backups, and CI pipelines in place; your team trained, or DPI operates.

FAQ

Questions about web application development

Do you build marketing websites too?

Yes, when substance matters: fast, structured, SEO-ready sites on a static or Next.js stack. This website is an example of the approach.

How do you ensure performance?

Performance budgets from the start, server rendering where it helps, efficient data loading, and Core Web Vitals measured on every release.

What about accessibility?

Accessible components, keyboard and screen reader support, and checks in the pipeline, aligned with WCAG expectations.

Can you take over an existing application?

Yes. We assess the codebase, stabilize what needs it, and modernize incrementally rather than rewriting everything at once.

Where is it hosted?

On AWS, Kubernetes, or Cloudflare in your account or ours, with monitoring, backups, and CI pipelines.
