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 paid discovery sprint
First 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. You get a written scope, an architecture and a costed roadmap.
A quote based on your product
You see cost and timeline before development starts. We price the outcome, and the estimate comes from your real product and its workflows.
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 enterprise partners
For FeelEat’s enterprise partners we built a React portal over FeelEat’s core systems: dashboards, orders, subscriptions and live restocking data in one place, on a React + Node.js + NestJS stack. Support call volume fell 68%, restocking accuracy reached 94%, and partner NPS climbed from +38 to +71.
Questions teams ask before hiring React developers
Resúmelo en un brief. Un ingeniero sénior —no un comercial— responde en un día laborable.
What React work has CODT Technologies actually shipped?
Named, linked production systems: LeadTrack AI’s agent-configuration console, FeelEat’s Smart Client Portal for enterprise partners, the FeelEat admin and recipe portals that run the back office, and the React web surfaces of Bizzabo’s event platform and 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 uses React Native’s NFC host-card emulation so staff clock in by tapping a phone — in under a second, offline-safe.
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. Next comes a paid discovery sprint, which ends in a written scope and a fixed quote. The build team starts 4–5 business days after you sign the quote.
