Challenges

Upgradability of Mobile Vikings system to Polish telecom network standard

Outsourcing of development and operations (DevOps)

Development of a mobile native app

As technologies and business markets change practically at the speed of light, Mobile Vikings wanted to get the best professionals from the Polish market who wanted to work on new, even very difficult tasks with tight deadlines. After a few weeks of searching the market and considering many possible options, Mobile Vikings decided to start the cooperation with Ulam Labs in 2016.

Results

Thanks to the efficient development approaches, Mobile Vikings was able to deliver real value to its customers.

The main achievements

reliable Mobile Number Portability

microservices that effectively support the auto top-up process

best in class of a mobile native app

high security transaction system

a work acceleration platform which enhances log aggregation, continuous delivery and implementation

The steps of system upgrading

Creating a structure that would make the system scalable

Implementing a new algorithm that would enable transfer phone numbers automatically

Rewriting the legacy code according to best practice

Testing the application to make sure the improvements within the Mobile Vikings products make the system stable

Key functionalities

Mobile number portability process (MNP)

Technically, MNP process is the facility that helps to switch from one mobile phone network service provider to another in any licensed service area (e.g. a country) while remaining an existing telephone number and avoiding the costs of switching between operators. Mobile Vikings wanted to receive a software module which allows the company to transfer phone numbers both automatically and effectively from other mobile operators.

Payment management system

The basic challenge was to create a seamless payment service with a high transaction security rate.

Ulam Labs has been assisting internal MVs team adding new features to provide better system performance and business edge.

Currently, the team consists of:

5 Ulam’s employees including 3 frontend and backend specialists and 2 mobile app developers,
4 MV’s development engineers, 2 quality assurance specialists, UX, product design and management team.

Deployment environment

MV used to work on Amazon Web Service, however the system had a lot of issues with deploying new platform features. The company wanted to have a stable, easy-use system for testing new features.

Auto top-up

The technology enables your mobile account to be topped up automatically once it gets to a preset limit, involving your credit card only. The challenge was to top-up a user’s account correctly, without potential multiple top-ups.

Mobile App

Mobile Vikings wanted to receive a complete native app, which would have more features and get more powerful interface, and back-end

Used technology

The tech stack:

Besides the mentioned solutions, Ulam Labs also added a new tool - Elasticsearch. The centrally-stored data search and analytics engine helped solve the problem of a growing number of use cases and managing the cases in a proper way. Apart from this, an SQL Database was created based on MySQL and PostgreSQL relations. To create, change, and improve infrastructure, Ulam Labs used HashiCorp Terraform. The open source tool that codifies APIs into declarative configuration files which can be shared amongst team members, treated as code to view current versions, review, and edit.
