Web Development

Web applications that stay fast after launch day

We design, build and run web products for startups and enterprises. Senior engineers own your codebase from database schema to the last pixel, so features ship faster and break less.

What we do

What we offer

Custom web apps, SaaS products and enterprise portals built on React, Next.js and .NET, designed to stay fast and maintainable as you grow.

Process

How we deliver

01

Discovery

We map users, workflows and constraints, then agree scope, risks and success metrics in writing.

02

Architecture

We choose the stack and design data models and APIs for the scale you expect, not just day one.

03

Iterative build

Two-week sprints with a working demo at the end of each. You see progress, not status reports.

04

Launch & scale

Load testing, monitoring and a staged rollout. After launch we tune performance with real data.

FAQ

Web Development FAQs

Can't find your answer? Ask us directly.

Which technologies do you use for web development?

Mostly React and Next.js with TypeScript on the frontend, and .NET Core, Node.js or Python on the backend, with PostgreSQL or SQL Server. We recommend a stack based on your team, scale and hiring plans, not on fashion.

Can you take over an existing codebase?

Yes. We start with a one to two week code and architecture audit, share a prioritised list of risks and quick wins, and then take ownership in stages.

Who owns the code and IP?

You do. All code lives in your repository from day one, and IP transfers to you under the contract. We sign an NDA before any detailed discussion.

How long does a typical web application take?

An MVP usually takes 8 to 14 weeks. Larger enterprise platforms are delivered in phases, with the first production release typically within three to four months.
