Ruby on Rails (ROR) is Fidenz’s primary framework for web application development. Years of expertise enables Fidenz to deliver successful projects via ROR. Our engineers use a fine set of gems to build applications that provide reliability, scalability, easy maintenance, and delivery in complex web solutions
Fidenz has done many ROR based integrations using open standards. We have shared our knowledge of ROR and other platforms by contributing for many open source projects. Our expertise enables us to integrate ROR based custom applications with many different services, to deliver right functionality for products. Over the years, we have deployed our applications to many different hosting environments reliably.

Fidenz History with Ruby on Rails

We have been developing apps via Ruby on Rails since 2013. Prior to ROR, we have used .Net and PHP for backend scripting that were beneficial for web development.

Best practices and discipline surrounding Ruby on Rails convinced us of its superiority. Coding conventions, strict Object Oriented Programming Model, use of ORM, and availability of finely crafted gems (modules for Ruby) encourage our engineering team to learn and master the language, so to rely on ROR for any future projects.

The team spent three to six months on the technology, to come up to speed with it. Our experience with various languages and technologies helped us understand the fundamentals easily and to become productive quickly.

Ruby on Rails Development

Ruby on Rails (ROR) is our preferred language and framework for all our web application developments. Over the last five years, we have delivered solutions for e-commerce, mobile application backend (iOS & Android), admin portals, content management systems, and forums using ROR. Our unique project delivery process complements successful delivery of solutions using ROR. You could find more details of such solutions in our portfolio page.
Our preferred online store engine is SpreeCommerce. Our technical know-how with Ruby on Rails and familiarity with SpreeCommerce lead us to become one of the few technology partners of SpreeCommerce. As their partners, we could work on their Wombat Platform that provides connectivity between different e-commerce related SaaS platforms.

As part of the development related to Wombat, we have the ability to work with globally renowned platforms such as Xero and TradeGecko to develop integrations between such systems and Wombat.

Open Source with Ruby on Rails

As part of the partnership with SpreeCommerce, we have done some open source integration that gave us the opportunity to understand the architecture of Wombat, SpreeCommerce, and other third party platforms.

Noteworthy Open Source Contributions

Ruby on Rails Third Party Integration


This is an integration module to connect any admin portal or CMS with IBM Netsuite Platform. This integration enables the authentication of users, user profile management, membership management, and all types of payment processing.


The integration module to connect Moodel (open source learning platform) with any admin portal or CMS allows user management, single-sign-on (SSO), and synchronization of course details between Moodle and external applications.


For the platforms we develop, our choice of object storage is AWS S3. We have been using S3 for many years and we seamlessly integrate S3 for secure and reliable object storage.

AWS Video Transcoder

We deliver complex video-based online solutions. We have worked extensively on video content, and delivery of such. Our preferred choice is AWS Video Transcoder, which provides wide range of capabilities to produce and deliver video content for a range of devices with different capabilities, using formats such as HLS / RTSP.


Notifications wake up mobile devices. To handle such complex native notification capabilities of iOS and Android, different platforms had sprung up. To integrate these platforms, we use Firebase.

Payment Gateways

Most web portals require payment gateways integrated to the web site. We are experienced in working with multiple payment gateways, catering to customer desires. Considering the volume, average transaction size, and type of targeted customers, we work with our clients to decide on the most suitable payment gateway for their business.

We have integrated different offerings from various payment gateway providers such as PayPal, and FirstData to give the best ROI for our clients.

Ruby on Rails Toolbox

Over the years of Ruby on Rails usage, we have come to like a selected set of gems. These could be reliably used in any solution we develop. We have used these gems multiple times and we dig deep into codebases, to be efficient and well-versed in these.

Ruby on Rails Hosting

Hosting Services

Solutions we have developed using Ruby on Rails have different traffic, storage, processing and memory requirements. To handle these different requirements in a cost effective and reliable manner we have worked with multiple different hosting service providers. We recommend hosting systems in AWS EC2 as that provides many other services within the ecosystem itself. But depending on specific requirements such as simplicity of management and pricing, we host systems on Heroku and DigitalOcean as well.

Hosting Environments

Our prefered hosting server environments for Ruby on Rails application hosting has been Linux based but we do host on multiple flavours of Linux such as Ubuntu, CentOS and AmazonLinux. We recommend using either Apache or Nginx web servers with Passenger for best performance and we used Nginx as reverse proxy with Unicorn
