Web application development services

Our web application development services cover design, a React or Next.js front end, a Python and Django backend, QA and support after launch. We have worked on the Zeronest platform since January 2024 and logged 11,220 hours of engineering work so far.

Benefits of custom web app development

A decision made every minute

A web application built around your process removes the manual steps between "we decided" and "it's done." On the Zeronest platform we build, the system re-decides what a home battery should do once every minute, weighing live prices, tariffs and weather data - a decision no person could make by hand for more than 3,000 prosumer storage installations at that pace.

Three modes, one codebase

Custom web application development lets the product change shape as your business does, instead of forcing your business to fit someone else's software. The Zeronest platform now runs in three modes - off, manual and automatic - and serves homeowners, installers and cooperatives from the same codebase, each seeing only what their role needs.

400 screens, 21 landing pages

A web app reaches every device through a browser, without the cost of separate native builds for every platform. In one project cycle for BizBot, an Oslo-based startup automating business administration, we designed 400 screens and 21 landing pages. BizBot went on to raise 6.4 million Norwegian kroner and win a place in the Copenhagen FinTech accelerator.

MQTT, TLS 1.2, EU data residency

A web application that handles client data needs encrypted connections and a clear rule on where the data is stored. The Zeronest platform, which handles home energy data, encrypts device-to-cloud traffic over MQTT and TLS 1.2 behind AWS IoT Core, with client data kept inside the EU.

React development company: what we build with React and Next.js

Order Group builds React and Next.js front ends together with the backend behind them, as part of our custom software development work. Four platforms from our case studies:

  • Zeronest: the web management platform runs on Next.js, MUI and Redux Toolkit, the two mobile apps on React Native, and the backend on Django REST Framework, deployed to AWS.
  • Enerace: a web app in React with TypeScript and Redux Toolkit on a Django GraphQL API. One team builds the web app and the React Native app, and the front end moved to TypeScript in 2023.
  • Skyfri: a React front end on a Python asyncio backend, with a Databricks data pipeline, hosted on Azure.
  • KYOTO: the interface of a SCADA-based system for thermal energy storage, built in React.

Why build with us?

The same team, the same process, project after project.

We stay on the platform after launch

The same team has kept building the Zeronest platform since January 2024 and has logged 11,220 hours of engineering work so far. We count a platform as "done" only while it is still maintained, so there has been no handover, no re-onboarding and no lost context between releases.

Design and build for BizBot and Zeronest

For BizBot we designed 400 screens and 21 landing pages. After that work, BizBot raised a 6.4M NOK funding round and won a place in the Copenhagen FinTech accelerator. For Zeronest we built a platform that covers 16 inverter brands and, as of April 2026, more than 3,000 prosumer storage installations.

We work in short sprints, visible to you

Every sprint on the Zeronest platform has followed the same Scrum rhythm since 2024: one- or two-week sprints, a visible backlog, a demo you can sit in on. That rhythm has held for more than two years and 11,220 hours of logged work.

  • Depending on the type of application, we build with Next.js, React, Python, Django and Node.js, adjusted to your business goals. The Zeronest platform we build runs on Next.js on the web and Django on the backend, deployed to AWS.

  • The project's requirements determine the makeup of each team: a Project Manager, UX/UI Designer, QA Tester, and Front-end and Back-end developers. On the Zeronest platform, the same team has stayed on the project since January 2024.

  • Our process is well documented and outlines every step we take, from brief workshops to releasing the product. We divide the project into smaller sprints and break high-level sections into tasks that act as a roadmap. We used this same process to take Zeronest from a basic monitoring dashboard to a platform now covering 16 inverter brands.

  • We work in one- or two-week Scrum sprints and keep every process and change transparent. That rhythm has run continuously on the Zeronest platform since January 2024, with a demo at the end of each sprint.

  • Yes - for platforms that keep evolving, that is our default model. Zeronest, which debuted at Intersolar Europe in June 2024, is still in active development. On top of the original monitoring app, the same team added a demand-side response module, which lets users sell stored power back to the grid, and, in 2026, subscription billing.

  • The scope depends on the features of the first release, the systems the app has to integrate with and how long it will be developed after launch. Typical engagements run from three months to over a year. Basic discovery is free, and after it we estimate the cost, timeline and team. To start, please contact us.
