Django experts for the site you have.

Unlike most developers we specialize in improving and maintaining existing Django sites.

For the business that already has a Django app

You've already been through the process of designing, developing, and launching your site, and now...

  • The Minimum Viable Product you've been patching for months is looking a lot less viable right now.
  • Your development team is frustrated and slowed down by technical debt.
  • It's hard to confidently add new features for your customers.

Wellfire Interactive are the only developers uniquely focused on helping customers like SaaS businesses with their existing or legacy Django applications.

Leverage your existing Django project

You've already been through the process of designing, developing, and launching your site.

The cost of repeating this process combined with the cost of migrating and the risk of losing knowledge baked into your existing app is all too often greater than the cost of renovating an existing site.

For a production site like a SaaS app a rewrite means replacing a working asset.

We can help solve frustrations and keep you, your team, and your business moving along.

What we do

You've already been through the process of designing, developing, and launching your site... greenfield development and legacy work are similar and yet as different as building from scratch is from renovating an existing building.

  • Created a replicable deployment strategy based on continuous integration for a SaaS client taking away the fear of deployments that plagued new feature additions.
  • Identified and validated architectural changes for a health care SaaS with prioritization that let the in-house team focus on meeting on new business requirements.
  • Reduced the test run time by 100x from almost two hours to under two minutes for a SaaS client and designed a strategy for architectural changes that enabled a trebling of feature development.
  • Designed and implemented a microservices strategy for a trade association to add workflow functionality for an existing e-commerce site. This allowed them to avoid using a custom e-commerce platform, saving multiples of the cost of microservice development and costly staff training.
  • Integrated a custom job and candidate workflow Django app for a geospatial intelligence contractor.

We work with clients on one-off projects and long-term engagements based on your technical and business needs.

Comprehensive Roadmap

The comprehensive roadmap builds off of the basic check to provide you with deeper insight into your app and a confident plan for how to attack both technical issues and business features. $5000 fixed project price. Request a review & roadmap.

The goal is to define the scope of the project and its goals to develop a fixed scope, discrete project. Request a free consult.

Ongoing Development

When the scope is vague or your business needs more indeterminate we can work with you on a by-the-week basis. Request a free consult.
