Web app development
Web application development — SaaS products, portals and platforms
We build web applications that real customers log into and pay for: multi-tenant SaaS products, customer portals and internal web platforms. Authentication, billing, roles and an admin panel are part of the first release, not an afterthought.
Scope
What a web app from us includes
The parts that make a web product usable by paying customers — built in from the start.
Payments & subscriptions
Billing through Stripe or your payment provider: plans, trials, invoices and usage limits.
Admin panel
The back office your team needs to manage users, content and support cases.
Real-time features
Live updates across users with WebSockets — boards, chat, notifications.
APIs & integrations
Documented REST APIs (OpenAPI) and integrations with the tools your customers use.
Performance & SEO
Fast, server-rendered pages with Next.js where search traffic matters.

Delivery
How the project runs
The same four phases on every project. Only their length changes with scope.
1. Discovery · 1–2 weeks
Interviews with the people who will use the system, a map of the current process, a written specification and an estimate. The documents are yours even if you build elsewhere.
2. Architecture · 1–2 weeks
Data model, integrations, infrastructure and a milestone schedule. This is where the scope, price and launch date are fixed in writing.
3. Build · two-week iterations
A working demo every Friday and a staging environment you can open at any time. Changes in scope are priced and agreed before they are built.
4. Launch & support · ongoing
Deployment, handover, documentation and training, then a support arrangement sized to the business.
Pricing

Typical ranges for US clients at 2025–26 senior remote rates. The fixed price is agreed in writing after discovery.

FAQ
Questions we are asked most
How long does it take to build a web app MVP?
Typically 6–10 weeks from the end of discovery to a production launch, with a working demo every Friday along the way.
Which technologies do you use for web apps?
TypeScript across the stack: React or Vue with Next.js on the front end, Node.js with NestJS or Fastify on the back end, PostgreSQL for data, deployed to AWS or Cloudflare.
Can you take over an existing web application?
Yes. We start with a short code and infrastructure review, document what is there, and then extend or stabilize it.
Will the app scale?
We design the data model and boundaries first, so growth means adding capacity, not rewriting. Most products we build run on simple, inexpensive infrastructure until real load requires more.
