Web app types we deliver.

Every project follows our AI-First methodology - AI-assisted development, automated testing, and intelligence built into the product from day one.

Dashboards & analytics platforms

Real-time operational dashboards, executive reporting tools, and self-service analytics platforms with complex data visualisations. We handle high-frequency data streams and sub-second query performance.

AI features built in

Every web app we build includes an AI assessment in discovery. LLM-powered interfaces, intelligent search, AI summarisation, and agentic workflows are designed in - not added as afterthoughts.

Our web app stack -
chosen for your context.

Frontend

  • React 18 / Next.js 14 - our primary frontend. SSR, SSG, and App Router for performance and SEO.
  • Angular - for enterprise apps where a strong opinionated framework and TypeScript-first development matter.
  • Vue.js / Nuxt - for teams with Vue expertise or projects that benefit from a lighter framework.
  • TypeScript across all JS projects - no exceptions. Type safety reduces production bugs measurably.
  • Tailwind CSS for utility-first styling with consistent design tokens across large teams.

Backend

  • Node.js / Express / Fastify - our go-to for APIs, real-time features, and TypeScript backends.
  • Python / FastAPI / Django - for AI-heavy backends, data processing, and ML-adjacent services.
  • Java Spring Boot - for enterprise systems requiring JVM stability and the Spring ecosystem.
  • .NET Core - for Microsoft-stack organisations or where Windows services are involved.
  • Go - for high-throughput, low-latency API services where Node.js shows limits.

How we choose a stack: We don’t have a favourite. We ask: what does your team already know? What’s your hosting environment? What’s the performance profile? What integrations are needed? The answers determine the stack - not our preference.
