Web Application Development

What We Build

Web Applications That Are Fast by Design, Not Luck

We build web applications with React and Next.js on the frontend, Node.js or NestJS on the backend — a stack we've refined across 35+ projects to deliver consistent performance, SEO visibility, and developer experience.

Our web applications are tested for performance (Core Web Vitals), secured against OWASP vulnerabilities, optimized for SEO, and deployed with CI/CD pipelines that make future updates predictable and safe.

Whether you're building an internal tool, a customer portal, a complex data-heavy dashboard, or a public-facing product — we architect for the scale you're targeting, not the scale you're at today.

Our Web Stack

Next.js 14+ — App Router, SSR, SSG, API routes

TypeScript — type-safe throughout frontend and backend

Tailwind CSS — consistent design system at speed

Node.js / NestJS — scalable API layer with clean architecture

PostgreSQL — relational data with proper indexing strategy

Redis — caching, sessions, and real-time features

Web App Types

Types of Web Applications We Specialize In

Analytics Dashboards

Data-rich dashboards with real-time charts, filtering, export, and role-based views — for operations, sales, finance, and executive audiences.

Customer Portals

Self-service portals where your customers can manage their accounts, view data, submit requests, and access documents — reducing support load significantly.

Internal Tools & Admin Panels

Powerful back-office tools for your operations team — CMS interfaces, approval workflows, bulk management, and audit logs.

High-Traffic Public Platforms

Consumer-facing web apps with SEO optimization, CDN delivery, caching layers, and architecture designed for sudden traffic spikes.

Engineering Depth

Full-Stack Web Engineering, Proven in Production

We built NextInQue — a multi-tenant queue management SaaS running on this exact stack — so you're not paying for a team learning on the job. Every technology listed below is production-verified.

Frontend

App Router, SSR, dynamic dashboards — built with Next.js 16 and MUI v6 in the NextInQue product.

Backend & API

Express + TypeScript, clustered across CPU cores, Zod-validated, with clean module-level separation.

Database & Caching

PostgreSQL with indexed multi-tenant queries, Redis for pub/sub and session caching — both in active production.

Real-time & Queues

Queue status pushed live to customers via Socket.IO rooms with Redis adapter for multi-worker consistency.

Observability

Full-stack observability stack — metrics, structured logs, and alerting — all self-hosted alongside the app.

DevOps & Infrastructure

Docker Compose multi-service stacks, Nginx reverse proxy, zero-downtime restarts, and automated DB migrations.

Auth & Security

Dual JWT token pairs (tenant + admin), bcrypt hashing, XSS sanitisation, and explicit CORS allowlists.

Testing & Quality

API integration tests against a real database, migration consistency checks, and Playwright E2E — no mocks that lie.
