Bespoke software,
built to last.

Web apps, mobile, APIs, and backend systems — built on modern stacks, handed over with full source ownership. No lock-in, ever.

What we build

End-to-end custom software

From a single API to a full product — web, mobile, backend, and everything in between. Built properly, documented fully, handed over completely.

Web Applications

SPAs, multi-tenant SaaS platforms, internal tools, and enterprise portals. React and Next.js frontends with NestJS or Node.js backends.

ReactNext.jsNestJSTypeScript

Mobile Applications

Cross-platform iOS and Android with React Native. Shared codebase, native performance, real device testing before every release.

React NativeExpoiOSAndroid

Backend & APIs

RESTful APIs, GraphQL schemas, microservices, and event-driven systems. Documented with OpenAPI, versioned, and rate-limited from day one.

Node.jsGraphQLRESTMicroservices

Database Design

Schema design, Prisma ORM modelling, query optimisation, and migration strategy. PostgreSQL-first with Redis for caching and queuing.

PostgreSQLPrismaRedisMongoDB

Marketplace & Platforms

Two-sided marketplaces, booking systems, insurance comparison platforms — complex multi-tenant architectures with role-based access and payment integrations.

Multi-tenantStripeRBAC

System Integration

Connect your new software to existing ERPs, CRMs, third-party APIs, and legacy databases. We build the integration layer that makes everything talk.

RESTWebhooksERPCRM
Full source ownership
Every line of code is yours from day one. We hand over the repository, documentation, and deployment config — not a black box.
Full documentation
API docs, architecture diagrams, data models, deployment runbooks — delivered with the code, not as an afterthought.
Zero lock-in
No proprietary platforms, no vendor-only tools. Your team can maintain, extend, or hand to any other developer after we're done.
Our capabilities

How we build

We pick the right approach for each layer of your product — frontend, backend, mobile, and data — and build them to work together.

Frontend Development

Interfaces that are fast, accessible, and actually work

We build React and Next.js frontends with performance, accessibility, and maintainability from the start — not bolted on. Every component typed, every interaction tested, every page fast.

React with TypeScript — strict mode, no exceptions
TanStack Query for server state, Zustand for client state
CVA + three-layer CSS token system for design consistency
Next.js for SSR, SSG, and edge rendering where it matters
Playwright E2E and Vitest unit testing coverage

Backend Development

APIs that scale, don't leak, and are documented on day one

NestJS monorepo architecture with modular design — B2C, CRM, and Admin namespaces sharing a single codebase. Every endpoint documented with OpenAPI, every route guarded, every query optimised.

NestJS with TypeScript — Guards, Interceptors, DTOs
Prisma ORM with PostgreSQL — migrations, seeds, type safety
JWT + refresh token auth with role-based access control
OpenAPI / Swagger documentation generated automatically
Redis for caching, BullMQ for background job queues

Mobile Development

One codebase, two stores, native performance

React Native with Expo — shared logic across iOS and Android with platform-specific UI where it matters. We don't compromise on feel just because it's cross-platform.

React Native + Expo — managed and bare workflows
Offline-first architecture where required
Push notifications, biometrics, deep linking
Real device testing on iOS and Android before every release
OTA updates via Expo EAS — no App Store delays for bug fixes

Database Design

Schema design that won't collapse under production load

We design data models that handle the complex relationships your business actually has — not just the simple cases. Proper normalisation, indexes, constraints, and migration strategies from the start.

PostgreSQL-first — relations, constraints, RLS
Prisma schema design with full type inference
Migration strategy — zero-downtime schema changes
Query optimisation and index analysis
Redis for caching — reducing DB load by 60–80%

Architecture & System Design

Systems designed to grow with your business

We design for the traffic you'll have in 18 months, not just the traffic you have today. Modular monolith with a clear path to microservices when you need it — not premature complexity.

Event-driven architecture for async workflows

How we work

From idea to production

We move fast without cutting corners. Every phase produces something working and testable — not just a document.

01

Discovery & scoping

We map requirements, define the data model, agree on the stack, and produce a scoped technical specification before any code is written.

02

Architecture & design

System design, API schema, database model, component library — built in code, not just diagrams. You see it before we build it.

03

Agile build

Two-week sprints with working demos every cycle. Continuous feedback, no surprises, and a staging environment from week one.

04

Handover & support

Full source, docs, and runbooks. Deployment scripted. Team training included. We don't disappear after go-live.

Technology

Modern stacks. No exceptions.

We build on frameworks and tools that have strong communities, long-term maintainability, and proven production records.
