Our cooperation with Simbirsoft began with a single front-end developer. Literally in a month we made sure that the level of Simbirsoft developers' professional skills is very high and extended cooperation, involving additional specialists into other web-projects and later we also employed their testing service and mobile development. In a year of cooperative working Simbirsoft turned out to be a highly professional front-end and mobile development team and performed high-quality service. Thanks to their participation we implemented 6 large-scale projects that are very important to our company. It's worth noting that interaction established between ABBYY LS and Simbirsoft project leads as well as between developers had a very positive influence on further communication and improved mutual understanding, revealing common grounds in project development. All the managers setting tasks for SimbirSoft get full access to task accomplishment and time spending reports. Well-organized reports ensure deadline meeting and avoid budget overrun and provide online project implementation monitoring. Without any doubt Simbirsoft is a company to recommend for long-term partnership in software development sphere. Puha E., project manager Abby Language

Over the past 3 months we have been tightly collaborating with SimbirSoft while developing a website for the charity project “{Всем”. SimbirSoft team kindly took into account all our suggestions on the workflow. The development team showed us the current version of the project weekly, which allowed us to follow the progress and make course corrections in time. And collaborative planning and agility in task solution during the development process let us achieve our stated goals. Additionally, I would like to underscore the interest of the team in the result. Our colleagues from SimbirSoft developed the functionality according to our requirements, but also approached the process in a very responsible way: they suggested alternative realization options given time and budget. Flexibility, agility and willingness to do business are the qualities of SimbirSoft. Now we have a new collaborative project and we are sure we will have effective cooperation and a quality result. A. Protopopov, administration manager

We have engaged two specialists from SimbirSoft in the BACKLOG project development. We would like to thank your employees for their high professional qualities. The team is working in 2-week sprints. The first sprint began in early March. As a result of the seventh sprint, we got a fully functional solution launched in operation. All the tasks are implemented at a very high technical level. We have not had a single system error during the eight sprints of our cooperation which is the best evidence of high quality. All the wishes of the product owner (including the most audacious ones) are implemented in the GUI. The visualization is perfect. The colleagues take active part both in the arrangement of a high-quality workflow and in the development of the product improving its business value. In spite of certain difficulties and limitations, the accomplishment of tasks continues; the search for variants brings the desired result. The determination to push the matter through is their characteristic feature. We are delighted with the highly responsible approach to the tasks demonstrated by our colleagues: their proactivity is pleasantly surprising especially in those cases when they could have expected us to take the initiative. The constructive communication is established between all the project participants: they speak openly about the problems and advise respectfully. The work is flawless. For the other teams, we point out the specialists of SimbirSoft as a model to emulate. Their passion for the profession is the benchmark for the creation of a good team and development of a high-quality product meeting all the deadlines. Whenever necessary we are ready to tell you about the merits and accomplishments of SimbirSoft specialists. We are really happy with such a work proving the excellent quality of the outsource software development services provided by SimbirSoft. Alexander Bobrov, COO, the owner of the BACKLOG product

We would like to thank SimbirSoft Ltd for their excellent work, high level of professionalism and their assistance in developing Travelry mobile app. SimbirSoft specialists literally helped us save our projects, which another development team failed to develop. We began our cooperation in a critical moment when the previous development team committed a series of errors and then admitted they couldn't finish the project. In this situation we were searching for professionals with high level of expertise who could not only improve the app, but also deal with a number of challenges the project inherited from the previous development team. And we made the right decision by choosing SimbirSoft. At all the development stages we saw the professionalism and determination to get the best result within the shortest possible time. Their working process is very clear. The work schedule was elaborately discussed with the project manager who always provided instant solutions of emerging business issues. Before each stage specialists thoroughly studied the tasks, after each stage we received accurate and timely reports. A lot of tasks were done before deadline which reflects team's high level of professionalism. Thanks to this, we managed to implement more tasks than we initially expected. We are glad to cooperate with SimbirSoft and are planning to continue our collaboration, developing our project and putting new ideas into practice.

We are very happy to develop SmartCAT together with SimbirSoft! SmartCAT is a startup platform for translation automation. It means a lot for us and we pay much attention to its development. SmartCAT successfully advances on its life with the SimbirSoft Ltd help, to be more specific - we raised an investment round A, and won Skolkovo foundation grant in 2016. Good job! What we appreciate is agile development and ability to introduce the best user experience possible through modern technologies adoption. Our company keeps abreast of what`s going on in the software development world and, fortunately, SimbirSoft team shares our values and helps us to do so. Together we tried Polymer for our project and we were the first who did it in Russia! Even though we have finally settled with React JS technology, we were able to try different approaches and select the most appropriate ones, not just technologies we`re familiar with. So, what is the best in SimbirSoft? I would say expertise and good organization. High-qualified front-end specialists helped us to implement the best tools and practices in SmartCAT. We just relied on their expertise and got brilliant results. Project management is just another strong point in SimbirSoft`s offering. The development process is agile and well organized. To tell the truth, we have never used an outsource development service before. We thought that it is ineffective before SimbirSoft allayed our suspicions. We just posted a task and received the result we expected. Many thanks to the Simbirsoft team. We are looking forward to having other collaborative projects! Vladimir Gusakov, SmartCAT CTO&Co-ownner

PROGNOZ and SimbirSoft began cooperation in 2011. At different times SimbirSoft teams helped us to develop from 2 to 4 projects simultaneously. One should mention a remarkable experience of SimbirSoft in iOS and Android development as well as high proficiency in C#, Java, JavaScript and PHP. In 2015 we've chosen SimbirSoft as one of our contractors to develop a federal-financed project. We've developed an information system for Federal Accreditation Service (Rosakkreditatsiya). SimbirSoft acted as core developer and engaged a dedicated PHP team including developers and other specialists. They were working at a high pace and we deeply appreciate SimbirSoft’s understanding of our inside business process and maximum adaptation of all the participants to meet these requirements. Particularly noteworthy were the developers and testers team leads assuming coordination not only between themselves but also between other contractors and helping to resolve a number of unexpected situations. We recommend SimbirSoft as a worthy partner for complicated and very important state level projects! Istomina М. project manager

For seven years of cooperation, SimbirSoft has completed a variety of project for us, including desktop applications, cloud server and web applications. When we had a task to make a high-load web application we entrusted it to SimbirSoft to develop as they always possess required professional teams for us, their long-term customer. We were happy that SimbirSoft team managed to get into the subject area required: extension of the team due to specifics of our project or implementation of our immediate ideas the team was prompt enough to keep the promised timelines. We, at Gehtsoft USA, are very satisfied with SimbirSoft team collaboration. Elizaveta Gekht, Product Manager, GehtSoft USA LLC

We are happy to cooperate with SimbirSoft as they have proven to be a reliable partner.

We have been very much impressed by SimbirSoft’s ability to literally read our minds and deliver a state of the art prototype that perfectly symbolizes our vision of an upcoming product and conveys the stylish, elegant and modern image we needed to sustain the development of our multiplatform solution. The quality and a delivery of that prototype are exceeded our expectation. We look forward to working with SimbirSoft on all our upcoming projects.

I have worked with SimbirSoft for over 7 years. We worked together on a large, enterprise class SaaS application with a team of 10-20 people as well as smaller projects with only 1-2 developers. I have visited the team on numerous occasions and personally know the founders and the management staff. SimbirSoft has managed to hire and retain a very qualified and disciplined team that is being constantly challenged to learn new technologies, improve business and project management processes and to deliver to the customer the project within the timeline and the budget that were agreed upon. SimbirSoft not only listens to what the customer wants, but thinks creatively about the best way to achieve the customer's goals, proposes and defends alternative solutions. The engineers, both development and quality assurance, are highly qualified and engaged in their projects, whether augmenting a US team or being the only developers and testers on a project. I would highly recommend SimbirSoft to any US-based company that may be contemplating offshore development.

We had a great experience working with you guys.
