Full-Stack Web Apps
Custom web applications taken from concept to deployment — Next.js, Supabase, real-time data, auth, and admin dashboards. The same stack we built the Growth Nexus platform and client portal on, applied to your product.

Custom Web Applications
When off-the-shelf software can't do it, a custom app built right will.
A full-stack web app is software shaped entirely around your business — the interface, the logic, the data, and the integrations, all working as one. We build the whole stack: React and Next.js on the front, Node.js and Supabase behind it, deployed and maintained on Vercel.
The benefit is a product that fits exactly, scales cleanly from MVP to enterprise, and is yours to own and grow. We don't just recommend this stack — we run our own platform and client portal on it, so you get tools proven in production, not in a pitch deck.
The Full Stack
Every layer of your app, built in-house
Frontend Development
Fast, responsive interfaces built in React and Next.js — accessible, mobile-first, and pixel-precise. Modern UI that feels instant to use and holds up on every screen, from phone to widescreen.
Backend Development
Robust server logic, authentication, permissions, and the business rules your app runs on — built with Node.js and typed end to end so behaviour is predictable, secure, and easy to extend.
Database Integration
Well-modelled data on Supabase and PostgreSQL — relational structure, row-level security, and real-time updates so your app reflects changes the instant they happen, with data integrity built in.
API Development
Clean REST APIs, webhooks, and third-party integrations — payment processors, email, AI models, and internal systems connected with proper validation, error handling, and documentation.
Deployment & Maintenance
Shipped on Vercel with CI/CD, preview deploys, and monitoring — then kept healthy with updates, performance tuning, and feature work. Your app launches well and stays well past launch day.

Example Builds
The kinds of apps we ship most
A portal that replaces the email chain
Authenticated dashboards where customers track orders, message your team, view files, and pay invoices in real time — exactly the kind of portal we built into the Growth Nexus platform itself.
From idea to a working product
We take a concept and ship a real, usable MVP — auth, billing, core features, and an admin panel — on a foundation that scales, so your first users and your hundredth get the same fast app.
The dashboard your team actually needs
Custom admin tools and data dashboards that pull from your systems, enforce permissions, and turn spreadsheets and manual processes into one clean, reliable internal application.
Case Study · The Growth Nexus Platform
This very platform — and its client portal with auth, order tracking, real-time messaging, file sharing, and invoicing — is a Next.js + Supabase app we designed, built, and run ourselves.
Build Process
From first call to a live, maintained product
Step 1
Discovery
We define the product, users, and core features — turning your idea into a scoped plan with a fixed quote before any code is written.
Step 2
Architecture
Data models, auth strategy, and system design mapped up front so the app is secure, scalable, and maintainable from the first commit.
Step 3
Build
Typed Next.js and Supabase development with code review and CI checks — the same disciplined stack the Growth Nexus platform runs on.
Step 4
Test & QA
Real QA across devices and edge cases, with preview deploys so you see and approve every feature before it reaches production.
Step 5
Deploy & Maintain
Launched on Vercel with CI/CD and monitoring, then supported with updates, performance tuning, and new features as you grow.
Web App Questions
What clients ask before building an app
Have an idea or a rough spec? Tell us about your app and we'll scope it with you.
Next.js and React on the frontend, Node.js for server logic, and Supabase with PostgreSQL for the database, auth, and real-time data — deployed on Vercel with CI/CD. It's the exact stack the Growth Nexus platform and client portal run on, so we build on tools we trust in production every day.
MVPs typically start around $1,200 and scale with scope from there — larger platforms with billing, complex permissions, and integrations run higher. Every project begins with a fixed-scope proposal in writing, and we can phase delivery so you launch a usable product early and expand it as budget allows.
Yes — that's the ideal path. We architect the MVP on foundations that scale, so you ship quickly to validate with real users, then grow the same codebase into a full product without a rewrite. You're never paying twice because we cut corners early.
All of it. Secure auth with role-based permissions, payment and subscription billing, and custom admin dashboards are core to most apps we build. The Growth Nexus client portal includes exactly these — order tracking, messaging, file sharing, and invoicing behind authenticated accounts.
Yes. A typed codebase, sensible data modelling, real-time where it helps, and Vercel's edge infrastructure keep the app fast under load. We design for scale from the start — the same app serves your first ten users and your ten-thousandth without re-architecting.
We do. Every build includes a post-launch support window, and optional care plans cover monitoring, updates, performance tuning, and ongoing feature work. CI/CD and preview deploys mean changes ship safely, so the app keeps improving without risky big-bang releases.
