Web Apps

Web applications, built across the whole stack

Web apps built front to back — UI, API, and data model

We design and build modern web apps end to end — the front-end your users work in, the API layer that powers it, and the data model underneath. One team across all three.

Overview

How we help

Web Application Development at Mariyano covers the full picture: a responsive interface, a clean API layer, and a data model designed to hold up as the product grows. We build the parts that matter rather than bolting features onto a template.

We work with stacks we know well — React or Next on the front-end, Node or Python on the backend, and SQL or NoSQL data stores chosen to fit the problem. The technology follows the requirements, not the other way around.

This is the same engineering team behind our own products, so you get the standards we hold ourselves to: documented APIs, sensible architecture, and software that stays maintainable long after launch.

Capabilities

What's included

Front-end interfaces

Responsive, accessible web interfaces built with React or Next, designed around the work your users actually do.

Backend APIs

Well-structured API layers in Node or Python that keep business logic clear and the front-end thin.

Data modelling

Data models in SQL or NoSQL designed to fit your domain and stay sound as the application grows.

Integrations

Connect the systems you already run through documented APIs, so data moves between them instead of being re-keyed.

Auth and access control

Authentication, roles, and permissions built in from the start, so the right people see the right data.

Deployment and scaling

Apps shipped to cloud infrastructure with the room to grow as usage and data volumes increase.

How we work

Our approach

Understand the problem

We start with how your users and processes work today, then agree on what the application needs to do before any code is written.

Design the architecture

We shape the data model, API surface, and front-end structure together, choosing the stack that fits rather than a default.

Build in increments

We deliver in working slices you can review, so the product takes shape against real feedback instead of a long silent build.

Ship and support

We deploy to your infrastructure, hand over documented code, and stay available to maintain and extend the application.

Use cases

Where it fits

Internal operations tools

Web consoles and admin systems that replace spreadsheets and manual handoffs with software your team can rely on.

Customer and partner portals

Secure, self-service portals where external users submit, track, and manage their work with your business.

Dashboards and reporting apps

Interfaces that pull data from across your systems into current, actionable views rather than stale exports.

Data-driven products

Customer-facing web products where the front-end, API, and data model all have to work together at scale.

FAQ

Common questions

Which technologies do you build with?

Typically React or Next on the front-end, Node or Python on the backend, and SQL or NoSQL for data, chosen to fit the project. We pick the stack around your requirements rather than forcing one default onto every build.

Do you build the backend and database too, or just the interface?

We build all three — the front-end, the API layer, and the data model. They are designed together so the application is coherent end to end rather than a UI stitched onto someone else's backend.

Can you work with our existing systems?

Yes. We integrate with the systems and data you already run through documented APIs. Tell us about your setup at our contact page and we will talk through the approach.
