[Application development](<https://manitu.si/applications/>)

# Custom web application development

Portals, SaaS products and internal tools that run in a browser.

## What we can build

A customer portal for documents and requests, a SaaS product with subscriptions, or an internal tool to replace manual work across spreadsheets.

## How I plan a web application

We start with the users, their roles and their tasks. Then we define the data model, sign-in, integrations, and the scope of the first usable release. I work with Ruby on Rails on the backend.

## Production experience

As lead developer I built Jetpack Workflow from the start to thousands of daily users. I also develop eternalfriend.io, my platform for artists and makers.

## What application do you need?

Describe the users, the problem and the main features. If an application already exists, include a link and explain what you want to change. Your preferred timing and approximate budget are useful too.
