Web Applications

We build modern web applications using React, Next.js, and Node.js that are fast, accessible, and built to scale. Whether you need a customer-facing platform, an internal dashboard, or a complex SaaS product, we deliver production-quality software that your users will love.

Our web applications are server-rendered for speed, fully responsive across devices, and optimised for search engines. We build with TypeScript for reliability and use modern tooling to ensure your codebase stays maintainable as your product grows.

From single-page applications to complex multi-tenant platforms, we have the experience to handle projects of any scale.

Technologies we use

  • React
  • Next.js
  • Node.js
  • TypeScript
  • GraphQL
  • PostgreSQL

Mobile Applications

We build cross-platform mobile apps that feel polished and perform brilliantly. React Native is our go-to framework — it lets us share code with your React web app, ship to iOS and Android from a single codebase, and deliver a truly native experience without the overhead of maintaining two separate codebases.

For teams already invested in the .NET ecosystem, we also build mobile apps with .NET MAUI, giving you cross-platform reach while keeping your C# skills and existing backend integrations intact. We help you choose the right approach based on your stack, budget, and timeline.

Every app we build includes offline support, push notifications, and app store submission handled end-to-end. We also provide ongoing maintenance and updates to keep your app running smoothly.

What we deliver

  • React Native apps
  • .NET MAUI apps
  • Flutter apps
  • PWAs
  • App store submission
  • Ongoing maintenance

Cloud & Infrastructure

Every application we build is deployed on robust cloud infrastructure designed for reliability and cost efficiency. We primarily work with AWS but have experience across Azure and Google Cloud to match your existing environment.

We set up CI/CD pipelines, automated testing, staging environments, and monitoring from the start. Your application gets the same infrastructure treatment that enterprise teams expect, regardless of project size.

Post-launch, we provide ongoing support to keep your systems healthy, respond to incidents, and scale your infrastructure as your user base grows.

Included in every project

  • Infrastructure as code. We use Terraform and AWS CDK to define your infrastructure, making deployments repeatable, auditable, and version-controlled.
  • CI/CD pipelines. Automated build, test, and deploy pipelines so your team can ship with confidence multiple times a day.
  • Monitoring and alerting. Full observability with CloudWatch, Sentry, and custom dashboards so you know how your application is performing at all times.

Why Maven - Built to last, delivered on time

We combine two decades of software engineering experience with modern tools and frameworks to deliver applications that stand the test of time.

  • Full-stack expertise. From database design to pixel-perfect frontends, we handle the entire stack. No need to coordinate between multiple agencies or freelancers.
  • Agile delivery. We work in short sprints with regular demos and feedback cycles. You see progress every week and can adjust priorities as your business evolves.
  • Quality by default. Every project includes automated testing, code reviews, and performance benchmarks. We write code that your team can maintain long after our engagement ends.
  • Transparent communication. Daily standups, weekly reports, and direct access to your development team. No account managers filtering information between you and the people building your software.
  • Scalable architecture. We design systems that handle growth gracefully. Whether you go from 100 to 100,000 users, your application will be ready.
  • Post-launch support. We do not disappear after launch. We offer ongoing support, maintenance, and feature development to keep your product competitive.

FAQ - Web & mobile development FAQs

What teams ask us before committing to a build.

Should we build a Progressive Web App or a native mobile app?
PWAs are dramatically cheaper to maintain and ship to one codebase across web and mobile. We recommend native (React Native or Flutter) only when you need deep device integration, App Store discoverability, or the performance of native UI. We will give you an honest recommendation for your use case rather than defaulting to the more expensive option.
React Native or Flutter?
React Native if your team already knows React or you need tight integration with an existing React web codebase. Flutter if you are starting fresh and want best-in-class UI performance without web baggage. Both are production-ready; the decision usually comes down to team skills and design ambition.
Do you handle App Store and Play Store submission?
Yes. We handle the full submission process, including App Store screenshots, descriptions, privacy disclosures, age ratings, and the back-and-forth with Apple and Google reviewers. We have shipped through both stores enough times to know which rejection reasons to pre-empt.
How do you approach accessibility and Core Web Vitals?
Accessibility (WCAG 2.2 AA) and Core Web Vitals (LCP, INP, CLS) are baseline requirements on every project, not extras. We test with screen readers, keyboard-only navigation, and Lighthouse CI in the pipeline so regressions are caught before they reach production.
Can you take over a project from a previous agency?
Yes, and we do this regularly. We start with a 1-week handover audit — review the code, deploy pipeline, third-party integrations, and outstanding tickets — and produce a written plan with risks before we commit to ongoing work. About 40% of our engagements start this way.
