Continuous innovation

Our technology stack

We build robust, scalable solutions on mature tooling — chosen for how it holds up in production, not for how it trends.

Frontend and UI

Fast, accessible, consistent experiences. We prioritise perceived performance and smooth interaction on any device.

  • SEO-ready
  • Instant loads
  • Responsive design
Next.js
Hybrid rendering for web applications that are fast and search-engine friendly.
Angular
A robust framework for large business applications, with strict typing and signals.
Tailwind CSS
A utility-first design system that keeps the interface consistent and maintainable.

Backend and API

The backbone of your application. Secure systems that handle real load and genuinely complex business logic.

  • High concurrency
  • Data security
  • Modular services
NestJS
Modular architecture with dependency injection, validation and documentation built in.
Node.js
The right runtime for real-time applications and event-driven architectures.
Python
Data processing, AI and fast APIs when that is what the problem calls for.

Mobile development

Applications that feel native on iOS and Android, sharing the logic that is worth sharing.

  • iOS and Android
  • Offline-first
  • Store submission handled
Kotlin Multiplatform
Shared business logic with a native interface on each platform.
Ionic and Capacitor
One codebase for web, iOS and Android when time to market comes first.
SwiftUI and Compose
Native interfaces where the experience must be indistinguishable from the system.

Data and persistence

Correct data models from the start, with versioned migrations and verified backups.

  • Versioned migrations
  • Tested backups
  • Caching
PostgreSQL
A dependable relational database, with geospatial extensions when they are needed.
Redis
Caching and job queues with retries and concurrency control.
Prisma
Typed data access and real migrations — never manual changes in production.

Cloud and DevOps

Reproducible, automated infrastructure. We deploy, scale and monitor with practices you can verify.

  • Infrastructure as code
  • Observability
  • Reversible
Docker
Containers so software behaves identically across every environment.
Cloudflare
CDN, WAF and a global network for low latency and protection at the edge.
GitHub Actions
Lint, type, test and deploy pipelines on every change.

AI and integrations

Automation grounded in your own data, with quality evaluation and costs under control.

  • Grounded in your data
  • Measured costs
  • Continuous evaluation
Language models
Assistants and data extraction with clear limits and traceability.
REST and GraphQL APIs
Versioned, documented contracts so integration holds no surprises.
Queues and webhooks
Fault-tolerant synchronisation with retries and idempotency.
Our philosophy

Clean architecture and code that stays maintainable

We don't just write code — we design systems. We follow clean architecture and SOLID principles so your product stays maintainable, testable and easy to evolve as the business grows.

Security by design

Security practices from the first line of code, not as a patch at the end.

Automated CI/CD

Lint, types, tests and build on every change. Frictionless, reversible deployments.

What it looks like inside

A layered architecture with separated responsibilities and explicit boundaries.

  1. Client layer

    Web, mobile and internal panels consuming the same typed API.

  2. API gateway and load balancing

    One entry point handling authentication, rate limits and routing.

  3. Business logic

    Independent domain services: users, orders, payments, inventory.

  4. Persistence and queues

    PostgreSQL as the source of truth, Redis for caching and background jobs.
