Service

Web Application Development

Full-stack web applications from landing pages to complex SaaS platforms. React, Next.js, Angular, or Vue on the front. Go, Node.js, or Django on the back. Deployed and production-ready.

What this service covers

We build web applications across the full range: landing pages, SaaS platforms, internal tools, customer portals, and content platforms. Whatever the scope, every project is built for production with real users in mind - not as a prototype that needs to be rewritten once it gets traffic.

The technical approach starts before the first line of code. We define the data model and API contracts first, then design the UI against those contracts. REST or GraphQL depending on the use case. Authentication with JWT or OAuth 2.0. Responsive and accessible UI built to a component design that can be extended without rewrites.

Clients who work with Kalenux on web development work directly with the engineers building their product. They receive the full source code from day one in a Git repository they own. The stack we use is the same one we run on our own live products - proven under real traffic, not assembled from tutorials.

Deliverables and outcomes

Requirements and architecture document

Before development starts, we write down the data model, API endpoints, authentication flow, and component breakdown. This document is yours and serves as the project spec.

Complete source code

Full frontend and backend source, version-controlled in a Git repository. You own the repository and have access from day one.

REST or GraphQL API

A well-structured, documented API with consistent error handling, input validation, and versioning. Endpoints follow RESTful conventions or GraphQL schema design depending on what fits the project.

Admin dashboard

A management interface for your team to create content, manage users, view analytics, and control application settings - built alongside the main application, not bolted on afterward.

Database design and migrations

A properly normalised schema designed for the expected query patterns, with indexed columns and migration scripts that can be run against any environment.

Authentication system

Secure user registration, login, password reset, and session management. JWT-based API authentication or OAuth 2.0 integration with third-party providers (Google, GitHub, etc.) as needed.

Deployment configuration

Docker Compose setup, Nginx configuration, SSL/TLS setup, environment variable management, and a working CI/CD pipeline or deploy script.

Documentation and handover

API documentation, environment setup guide, deployment runbook, and a handover session so your team can operate and extend the application independently.

Our process

Every web project follows a structured sequence: we establish the requirements and architecture before writing code, build frontend and backend in parallel against agreed API contracts, then move through integration, testing, and a staging review before production launch.

Step 1Discovery and requirements - scope, user flows, constraints, and technical decisions documented
Step 2Architecture and API design - data model, endpoint contracts, authentication flow, component breakdown
Step 3Frontend and backend development in parallel against the agreed API contracts
Step 4Integration and testing - end-to-end flows verified, edge cases handled, performance checked
Step 5Staging deployment and client review - full application running in a production-equivalent environment
Step 6Production launch - DNS cutover, SSL, monitoring, and documentation handover
