Web App Development

WHERE YOU START

Any app with users and real data.

Maybe you need a portal where your clients can see their orders and invoices. Maybe you want to replace an internal process that today runs on shared spreadsheets. Maybe you are building a SaaS product from scratch. They all start from the same place: a well built web app.

Business dashboards

Real time views of the data that matters to you: sales, activity, operational metrics, updated automatically, not entered by hand.

Client portals

A space where your clients log in and see their orders, invoices or project status, without calling or emailing you to ask.

Internal apps for your team

We replace shared spreadsheets and email based processes with an app where your team works with the same data, updated in real time.

Authentication, roles and permissions

Secure login and role based access: each user sees and can change exactly what they are allowed to, and nothing more.

Connection to your own database

We design the data structure that fits your app, rather than working within the limits of a generic product or a standard CMS.

Connection to external APIs

The app talks to external services, payments, email, maps, other platforms, through an API, so data flows automatically without manual copying.

MVPs for SaaS products

We build the first working version of a SaaS product from scratch, designed to be extended later, not a throwaway build for validation.

Payments and subscriptions inside the app

We integrate payment processors for one time or recurring billing, directly inside the app flow, without confusing redirects.

Migration off a no-code product

We take an app built on a no-code tool that has hit its limits and rebuild it on proprietary, scalable code.

Performance and load time

We optimize the app for fast loading and smooth interactions, even with large volumes of data or many concurrent users.

Taking over an existing app

We review code written by someone else, identify what can be kept, and continue development without starting from scratch.

New modules on an existing app

We extend an app you have already built with new features, without breaking what already works for your users.

HOW WE BUILD

What a web app built by us includes.

A web app does not stop at the interface. Authentication, data and integrations matter just as much as what the user sees on screen.

AUTHENTICATION & ACCESS

A secure login, with clear roles from the start.

We build the authentication and role system at the foundation of the app, so each type of user gets exactly the access they need.

Secure login with password reset option

Separate roles: client, administrator, internal team

Sessions and access managed correctly, without common vulnerabilities

DATA & DATABASE

A data structure designed for your app.

We design the database starting from what the app needs to do, not from the limits of a generic product, so data stays consistent as the app grows.

A proprietary data structure, tailored exactly to your app

Real time updates, without page reloads

Backups and data integrity, built in from day one

APIS & EXTERNAL INTEGRATIONS

Your app, connected to the rest of the world.

We connect the app to payment processors, email services, other platforms or internal systems, through an API, without manual flows between them.

Payments and subscriptions integrated directly in the app

Email notifications and automated events

Connections to external APIs or existing internal systems

PERFORMANCE & SCALE

Fast today, fast with 10 times the users too.

We optimize the app and infrastructure so load times stay short, no matter how much the number of users or the volume of data grows.

Optimization for fast loading on web and mobile

Infrastructure ready for growth, without a full rebuild

Continuous monitoring after launch

FREQUENTLY ASKED QUESTIONS

Questions we get asked often.

A marketing website displays information. A web app has an account, authentication, data that changes in real time, and actions the user performs directly inside it, such as a dashboard, an order portal or an admin panel.

We mainly work with Next.js, for good performance and flexibility on both the interface and the backend. We choose the database and infrastructure stack based on the project.

Yes. We build authentication, roles and permissions tailored to your needs, so each type of user, client, administrator, employee, sees exactly what they should see.

A simple MVP with core functionality can be ready in 6 to 10 weeks. An application with multiple modules, roles and external integrations usually takes 3 to 5 months.

Yes, this is one of the main reasons to choose a custom web app over a generic product: we connect it to any external API or internal system you need.

We design the application for scale from the start: the database, infrastructure and architecture are built to withstand growth in traffic and users, not just to work at launch.

Yes. We keep adding modules and new features after launch, as the needs of the application evolve alongside your business.
