How Theodo Utilised Python for an Investment Bank

As Python experts, we worked with a major french investment manager, who needed a Python development agency to help create innovative asset management solutions.

We produced several specialist apps, allowing advisors to show investment simulations to their clients, and let them play with it. The whole backend for these apps is built upon several Python microservices, each specialised on a certain job, keeping them really simple and easy to work on for several teams. As an example, we got a microservice only handling the huge database and exposing data. Another one is taking care of sending emails for all the apps.

Using Python let us develop these modules rapidly and made it easy to create new backends on the fly. Furthermore, thanks to SQLAlchemy (an open source database library) we had no issue handling the massive database of our clients.

Django and Theodo

"Python is fast enough for our site and allows us to produce maintainable features in record times, with a minimum of developers."
Cuong Do,  Software Architect Developer at
Large developer community: Django has a very large online developer community, constantly improving existing modules and producing exciting new ones.  As software developers, this means we can access component libraries and a community of support to accelerate development for our clients.
Exceptional scientific libraries: Widely used by the scientific community for the past decade, Python is one of the best high level language for mathematical computation and machine learning. Which means if you are into Big Data, it is probably what you are looking for.
Django Philosophy: The Django framework takes care of all the hassle of setting up a web project and provides developers with specialist tools for many use cases (authentication, localisation, geographic data handling).

Why use Python & Django?

Django is a widely used web framework, its design philosophy emphasises rapid development and clean code. It comes battery-included with all the security, authentication and admin interface features you'd expect in a web application. Instagram, the Washington Post, Spotify and other large tech companies use it to power their websites. At Theodo, we've used Django to develop a range of web applications including a customer-facing platform which has been rolled-out nationwide, APIs for the backend of mobile applications, and more.
