Service

TypeScript Application Development

We build full-stack TypeScript applications from Lambda functions to React frontends — TDD-first, pair-programmed, and designed to be owned by your team.

Deliverables

What We Build

Every engagement produces production-ready, type-safe code your team can maintain, extend, and trust.

SSR, SSG, API routes

Next.js Applications

Server-side rendered and statically generated Next.js apps with optimised API routes, middleware, and edge-ready deployments.

REST / GraphQL APIs

NestJS Backend Services

Scalable, modular backend services built with NestJS — REST or GraphQL, with full OpenAPI documentation and dependency injection.

TypeScript handlers

AWS Lambda Functions

Lightweight, cold-start-optimised Lambda handlers written in TypeScript with proper typing for event sources, responses, and errors.

Monorepo type safety

Shared Type Libraries

Monorepo-ready shared type packages that keep your frontend, backend, and infrastructure contracts in sync across teams.

Jest, Vitest, Playwright

End-to-End Test Suites

Comprehensive test coverage from unit tests with Jest or Vitest through to Playwright browser tests — written before the implementation.

Deployment configuration

CI/CD Pipeline Setup

GitHub Actions workflows, deployment configuration, and environment promotion strategies so every merge to main ships safely.

Stack

The Technologies

A focused, modern TypeScript stack — chosen for type safety, ecosystem maturity, and long-term maintainability.

TypeScript
Next.js
NestJS
Node.js
AWS Lambda
Jest
Vitest
Playwright

Frontend

Next.js

Pages Router or App Router, server components, edge middleware, and seamless Vercel or AWS deployments. We write every page in TypeScript with strict mode enabled.

Backend

NestJS + Lambda

Structured, testable NestJS services for long-lived APIs and lightweight TypeScript Lambda handlers for event-driven workloads — sharing types across both.

Testing

Jest · Vitest · Playwright

Unit, integration, and browser tests written before implementation. Coverage gates in CI ensure the bar never quietly drops between sprints.

How We Work

Engagement Approach

We don't just write code and hand it over. We embed engineering practices that make the codebase yours long after the engagement ends.

1
TDD-First

Tests before implementation

We write failing tests before a single line of production code. This keeps the design honest, eliminates regression fear, and produces a living specification your team can rely on long after the engagement ends.

2
AI-Augmented

Claude Code on every project

We embed AI-augmented development with Claude Code into our daily workflow — scaffolding boilerplate, reviewing edge cases, and accelerating the tedious parts so our engineers spend their time on what matters most.

3
Pair Programming

Humans on the critical paths

Complex business logic, architectural decisions, and security-sensitive code get the eyes of two engineers. Pair programming on critical paths catches problems early and spreads knowledge across the team.

4
Infrastructure as Code

AWS CDK for every deployment

Infrastructure is code too. We define Lambda functions, API Gateway, DynamoDB tables, and IAM roles in TypeScript CDK stacks — version-controlled, reviewable, and reproducible across every environment.
