Custom applications

Custom web application development built to go live and stay live.

Client portals, internal tools, field apps and dashboards built on React and Next.js, with secure authentication, role-based access and a real backend. Designed around your workflow, engineered to last.
Why it matters

AI can generate an app in minutes. Getting it to production is the hard part.

AI app builders are great for prototypes. But apps that hold customer data need authentication, permissions, a secure backend and someone accountable when something breaks.

What we build

Web apps for real business workflows.

Client portals

Secure places for customers to onboard, upload documents, track status and message your team.

Internal tools & workflow apps

Replace spreadsheets and email chains with an app built around how your team actually works.

Field & compliance apps

Mobile-friendly checklists, inspections, sign-offs and records that hold up to an audit.

Dashboards & reporting

One live view of marketing, sales and operations data, pulled from the tools you already use.

Quoting, intake & calculators

Self-service tools that qualify buyers and hand clean data to your CRM.

Finishing AI prototypes

Started in an AI app builder? We harden it into something secure, maintainable and ready for real users.

Security & backend

Secure by default, not bolted on later.

Every app we build gets the backend engineering a business needs: authentication, permissions, a database you control and the monitoring to know it is working. That is the difference between a demo and software your customers can trust with their data.

  • Secure authentication: SSO, multi-factor and passwordless sign-in
  • Role-based access so every user sees only what they should
  • Encryption in transit and at rest for data and documents
  • Audit trails that record who did what, and when
  • Server-side validation and protection against the OWASP Top 10
  • Automated backups, monitoring and error alerts
  • Clean APIs and integrations with your CRM, email and accounting tools
  • You own the code, the data and the hosting account
Custom application portfolio

Apps we have designed and built.

Workflow app

Notice App

  • Template-based notice creation
  • Status tracking dashboard
  • Role-based access and audit history
  • React / Next.js
  • PostgreSQL
  • Secure authentication

Client portal

RevRex Client Onboarding

A secure onboarding portal that ends the paperwork chase for CPA firms.

CPA firms invite new clients with a private link. Clients work through a guided five-step checklist they can save and return to, upload documents into an encrypted per-firm library, and staff see a readiness queue that tells them who to onboard first. Encrypted in transit and at rest, with a full audit trail.

  • Private invite links and a guided five-step checklist
  • Encrypted per-firm document library and audit trail
  • Readiness scoring that prioritizes the onboarding queue
  • React / Next.js
  • PostgreSQL
  • Encrypted file storage

Field safety app

JSA App

Job Safety Analyses completed on site, not on paper.

A mobile-friendly app for completing Job Safety Analyses in the field. Crews break a job into steps, identify hazards and controls, and sign off on a phone or tablet. Supervisors review and approve from anywhere, and every completed JSA is stored and searchable.

  • Step, hazard and control builder
  • Crew sign-off on phone or tablet
  • Supervisor review and searchable records
  • React / Next.js

Process

How we build custom applications.

01

Discover

We map the workflow, the users, the data and the rules before any screens get designed.

02

Design

Clickable prototypes your team reviews early, so the app fits the way work actually happens.

03

Build & secure

React and Next.js front end, a real backend and database, with security built in from day one.

04

Launch & support

Training, monitoring and ongoing improvements once real users are in the app.

FAQ

Custom app development questions.

It depends on scope: the number of user roles, workflows, integrations and the level of security required. We start with a short discovery so the estimate is based on your actual requirements, not a guess.
