React developers for day-to-day business tools.
Our senior React developers build the tools people use all day at work: the React console where LeadTrack AI’s customers steer live voice agents, FeelEat’s B2B partner portal, and React Native apps that clock staff in and go with flight crews onto the ramp.
The four stages of a React project.
A free 4-hour workshop
In a free 4-hour workshop we map the workflows the interface has to support: who uses it, under what pressure, and with which data. Only then does anyone open a component library.
A quote based on your product
A written scope and a quote reach you within 3 working days. We price the outcome, the number comes from your real product and its workflows, and it is fixed before any code is written.
A full-stack team by default
The same team builds the React front end and the Node.js/NestJS API behind it, as on LeadTrack AI and the FeelEat portals. When a screen and an endpoint disagree, one team fixes it. Working software ships every two weeks.
Care after launch
The engineers who built your front end stay on after launch for new features, dependency upgrades and performance budgets.
Web, SaaS, mobile and design.
Web platforms & sites
React and Next.js sites that load fast: code-split, cached and checked against performance budgets so they stay fast after launch.
Website developmentSaaS front ends
Multi-tenant dashboards, role-based access and admin surfaces over a real API — the React portal pattern behind FeelEat’s partner and back-office tools.
SaaS app developmentReact Native apps
Cross-platform mobile where it makes economic sense — including hardware-level work like TapTime’s NFC clock-in and Aviatize’s companion app for flight crews.
Mobile app developmentUI / UX design
User research first, then design that engineers review: user journeys, prototyped core flows, usability tests and a design system the React code really uses.
UI / UX designReact interfaces that run live operations.
LeadTrack AI — the console that steers live calls
For LeadTrack AI in Australia we built the React dashboard where sales teams set up their voice agents: persona, scripts and qualifying criteria. Changes reach live inbound calls instantly, and every transcript lands back in the same console. The stack is React and Node.js on AWS.
FeelEat Smart Client Portal — one place for client companies
For FeelEat’s business clients we built a React portal on a React + Node.js + NestJS stack. A client company places special orders, manages its employees, sees the sales from its fridges, creates staff vouchers, sets holidays, changes staff numbers and books tasting events there.
Questions teams ask before hiring React developers
Put it in a brief. A senior engineer reads it and replies within one business day.
What React work has CODT Technologies actually shipped?
Named, linked systems we built: LeadTrack AI’s agent-configuration console, FeelEat’s Smart Client Portal for business clients, the FeelEat admin and recipe portals that run the back office, and the React web surface of RushTix’s ticketed live shows. The case studies are linked from this page, so you can check each one.
Do your React developers cover React Native too?
Yes, including hardware-level work. Aviatize’s React Native companion app follows flight crews onto the ramp, and TapTime’s wall kiosk reads staff badges over NFC, keeps working offline and syncs later.
Do you build front-end only, or full-stack?
Full-stack by default: the shipped pattern across LeadTrack AI and the FeelEat portals is a React front end on a Node.js/NestJS backend, built by one team. If you already have an API team, we integrate against your contract instead — we have done both.
How do you keep a React app fast as it grows?
We set performance budgets at the start. Code-splitting, caching and careful rendering are in place before features pile up, and the budgets are checked as each feature lands. Our website-development service page commits to the same standard.
Can you take over an existing React codebase?
Often. We start with a short code audit and write up a remediation roadmap covering component architecture, state management, performance and test coverage. Then we take over in phases while the product keeps shipping.
Who owns the code and the IP?
You do, 100%. Code, designs and infrastructure configuration transfer to you at delivery. We keep a support copy only with your written permission, and we sign an NDA when you ask for one.
How fast can React developers start?
A senior engineer replies within one business day. We then spend a free 4-hour workshop on the workflows your interface has to carry, and you get a written scope and a quote within 3 working days. If the scope is clear, the quote carries a fixed price; if not, a short paid discovery sprint comes first and is credited in full against the build. The build team starts 4–5 business days after you sign the fixed quote.
