Mosties - Premier Ruby on Rails and mobile development team
Building digital products since 2009

We're a digital consultancy building products for Web, iOS & Android

Who are we?

Mosties is a team of Ruby on Rails, Swift & Java experts who specialise in delivering custom-built web & mobile applications.

Based in London with additional offices in Riga, Latvia, we use a nearshore development strategy that lets us offer startup-friendly pricing while eliminating the negatives of offshore web development.

Quality & transparency
powered by Agile development

We are an Agile dev team. We build from scratch, develop and maintain existing code base with Ruby on Rails, Swift, Java, Elastic Search, PostgreSQL and MongoDB.

We believe communication is the key element of a successful software development project. Every project has a dedicated manager who will report on project progress each week. You will receive access to the staging site and the code repository hosted on Github, as well as access to Trello which allows you to follow progress. For daily communication we also use Slack channels inviting clients for team discussion - you'll never feel left out.

App Development + Mosties

Our focus is creating custom projects tailored to your technology needs. We build remote development teams, supervise the quality of code, provide advice, and design solutions supporting your business online.

Code Quality & Security

The code created by our programmers contains a layer of automatic tests, which ensures that the application functions smoothly at the each stage of development. The application code, together with a full development history and a backup of data, is stored in GIT - a secure version control system. To provide you with the highest quality of services we use a fully automated process of releasing subsequent software versions.

Code quality control is ensured by an intensive peer code review procedure - each line of code our programmers create has been verified and approved by a second pair of eyes before it is uploaded to the staging server and then migrated to production.

Technologies & Tools

The heart of our web development toolset is the Ruby on Rails framework. We choose Ruby because of its design elegance and the ability to boost our productivity. It enables us to deliver your project on shorter deadlines while maintaining the high quality of our work.

For mobile app projects we rely on native Swift (iOS) & Java (Android). If you'll ask us to work with PhoneGap or other non-native tools, we'll just "no!" :)


Based on the analysis of user feedback and internal arrangements, can continue to employ the Agile web development methodology. The development is based on weekly iterations during which a team of web developers builds the agreed features and fixes potential errors.

We start each iteration with setting the priorities and reporting the project’s progress to you. This stage lasts throughout the whole period of product’s life and development.
