RoR & Crystal Programming

Above, we mentioned that Ruby on Rails is great for startups due to its versatility and rapid prototyping. In our experience, there are also examples of successful cooperation with start-ups. 

Olivegrey - a store of designer's women clothing. In addition to Ruby and Ruby on Rails, technologies such as JS and Linux were also used in the development of the site.

Optimize Player - a universal platform for video marketing, which is one of the main directions in modern PR-strategies. Designed and built by us from scratch, the site allows marketing specialists not only to create videos that increase the conversion of leads but also to deal with everything related to protecting their content and processing user feedback.

TwinSlash also has experience in modernizing businesses. Such projects include various tasks, from the modernization of business processes to the implementation of complete CRM systems (we will talk about them later).

FTO is a business consulting company with more than 16 years of experience. During this time, the company was engaged in the implementation of information systems in business based on the 1C platform. TwinSlash developed a server for the FTO and implemented Redmine plugins, expanding their functionality. The operation with tags has been improved and the ability to all users, even those who do not have admin rights, to manage tags has been added. In general, all of Redmine’s operations have been optimized by adding features such as previews of downloadable documents of any format and creating reports on the appropriate parameters and templates.

We at TwinSlash are well aware that the work doesn't end after Ruby on Rails application was successfully launched. Maintaining the correct operating of the application implies a timely response to all emerging problems. Our company has experience managing such issues. We use a separate control panel to log all requests through the ticketing system. This allows us to structure the application support process and respond to fresh challenges on time, arranging them in accordance with their priority.

The second main rule adopted by our company to maintain the operating of applications is the constant update of Ruby on Rails software. Due to the fact that this framework is open source, corrections and bug fixes come quite often. Therefore, to support the application, it is very important to update the software on time.

Creating a product roadmap with constant changes based on the client's feedback completes the list of main directions that are used at TwinSlash to support the high-quality operation of applications.

In modern programming, ongoing code auditing is a fundamental principle of a successful project. Such an audit helps to understand the complexity of the code and holes in its security. Our company understands the importance of such an audit and uses both manual verifications by experienced specialists, as well as tools for automatic verification, with identification of major bugs and inconsistencies.

As for Quality Assurance, we understand that manual testing is ancient history. That is why TwinSlash has QA professionals working on creating code to implement automated testing.

This segment is a huge part of the TwinSlash experience. Of the many works performed in this field, we can recall:

- OpenBasket - a platform for ordering quality and healthy products at wholesale prices. 

- Boomkat - an online platform from Manchester, selling vinyl records and having consumers from more than 100 countries.

- Nimbus Health - a German site for selling medical cannabis to doctors and pharmacists.
And more.

We can also be proud of several projects in the field of logistics:

• Drive Sense is an application created by TwinSlash for the American company Esurance. This application is a management system for fleet cars. Drive Sense deals with everything related to property insurance of organizations and citizens. Using the application, you can track the speed of the car, its chosen route, possible violations of traffic rules, and location details.
• Fleet Management - an almost identical application, with rare exceptions.

We at TwinSlash understand the importance of streamlining documentation circulation and client management. Therefore, our company is engaged in the improvement of ready-made free CRM systems, as well as the creation and implementation of completely new solutions on Ruby on Rails.

We won't dwell on improving free systems. But the development of custom solutions using RoR is interesting. This method has several advantages related to the essence of the framework itself. The CRM systems created on Ruby and Rails are extremely customized, due to the flexibility of the framework. This allows you to add unusual solutions to the system.

We have already discussed the speed of work on Ruby on Rails, and it will also be useful in creating CRM systems. In addition to the fact that the result can be obtained quickly enough, the framework also allows you to rapidly make any adjustments, without risking the safety of your database (which happens, using more heavy-code languages, like Java).

This area helps companies that don't have their own CTOs or cannot hire one. CTO as a service is a kind of relationship when a client-company delegates the tasks usually performed by CTO to another company. In all the other processes you work with a CTO as he’s a part of your internal team. 

As an example, we can introduce you to ISP Telecom. This platform provides telecommunications services (TPP). TwinSlash fully assumed the responsibilities of CTO management by building provisioning and billing systems for the company, implementing AS2 (LNP, WLNP, BLIF) built-in interface, managing integration and interoperability and compatibility testing between ISPT and Bell, Telus, Rogers, and Videotron. 

Security issues are one of the main problems of the digital industry. In a situation where the vast majority of transactions and processes take place online, it would be foolish to expect that no one will take advantage of this. Therefore, the importance of website or application security is hard to overestimate. That is why TwinSlash provides its customers with security audit services.

In general, this process includes a large amount of work in various areas, including assessing the security policy, checking the system for reporting new problems, auditing database and code, creating an artificial load on the site/application, and so on.

At the moment, our company is engaged in a security audit for two new crypto exchanges - Hermesus (US market) and Hobit (world market). As you know, the issue of security in the crypto industry is the most important area. TwinSlash creates mechanisms to provide security for personal data of exchange customers, including their payment data, crypto-wallets, and so on.

Sometimes, the most useful action in a situation where it seems that nothing is possible to improve is to ask for opinions from the outside. Such consulting allows you to evaluate the product with a fresh look, which often helps to identify problems and deficiencies that weren't visible with a blinded eye. Our clients value our opinion and we are happy to provide our recommendations regarding any issues that don't require in-depth research.

In this section, we are talking about the development of highly loaded systems that must cope with a huge number of users and constantly updated data.

As an example of work in this direction, we can cite:

Dynamic Network Administration - a platform that in real-time collects and processes a huge amount of data from various devices, including telephones and modems. The system developed by us allows our clients to track any changes and the amount of information transmitted over a selected period of time. This system was created for several large American companies using corporate tariffs from the international telecommunication company Sprint.

Working on architecture for your future project requires the attention of software architects or senior developers' attention, since it might impact a project’s growth, overall delivery time as well as complexity of its maintenance. With our team’s experience building 135 projects for 14 industries we can avoid majority of architectural mistakes, some of those we’ve learned ourselves.

Another area of our great interest, as we believe that online learning is the future. Our company had the opportunity to participate in the development of platforms in this segment, for example:

Language Learning Platform dedicated to the study of the Ukrainian, Polish, Chech, Hungarian and Romanian languages. The peculiarity of the approach is that this resource uses the karaoke-style transcriptions in video lessons. Thus, language learning becomes more interactive - users listen and remember the pronunciation of new words.

Connection between two or more applications, via their APIs, that lets those systems exchange data. API integrations power processes throughout many high-performing businesses that keep data in sync, enhance productivity, and drive revenue. We have experience integrating 3rd party systems, like payment gateways, CRMs or task tracers using their existing API with the applications we build. In the same time we’ve created APIs for those projects that might need to be integrated to other systems, like APIs for logistics tracking systems for further integration with various ERP solutions.
