Solution Architects
  • Design of secure, modifiable, extensible, and fault-tolerant software architecture
  • Assessing the system architecture currently in place and working with the technical staff to improve it
  • Assessing the business impact that certain technical choices have
  • Proven experience in high-load multi-component systems
  • Superior knowledge of back/front-end technologies, modeling methods, programming languages (C#, Scala, Java, etc.)
  • Technical mentoring, technical QA

Igor Sheverov

Chief Technical Officer, Partner

"Hiring a solution architect is feasible to create a complex system or to run the system audit on a regular basis and improve the software. We often recommend employing a part-time architect for the maximum efficiency."

Back-End/Full-Stack Developers
  • Proficient knowledge of back-end programming languages and frameworks
  • Understanding of front-end web technologies (HTML, CSS, JavaScript, React, Angular, etc.) or good experience in the essential front end (for full-stack guys)
  • Wide experience with databases, caching (Oracle, PostgreSQL, Redis, etc.)
  • Ability to design and develop integration APIs, experience with business process management tools
  • Hosting environment management (clouds, Linux, nginx, Apache, etc.)
  • Knowledge of accessibility and security compliance

Igor Sheverov

Chief Technical Officer, Partner

"There are development tasks that full-stack specialists can handle efficiently. Yet, for most cases, both back-end and front-end software development is required as it allows achieving more balanced teamplay and high performance, especially if your project team is a large one."

Front-End Developers
  • Implementation of the front layer of an application, participation in API design
  • Superior experience with front-end technologies and frameworks (JavaScript, CSS, LESS, React, etc.)
  • Experience with RESTful services and APIs
  • Responsive and mobile design, cross-browser development
  • Ability to work with content management systems (Umbraco, etc.)
  • Knowledge of microfrontends

Igor Sheverov

Chief Technical Officer, Partner

"We recommend hiring dedicated front-end developers for the software products requiring a dynamic and complex user web interface. Our front-end experts stand for quality and hands-on expertise, so we know pretty well how to deliver the best software solutions for our clients."

Mobile Developers
  • Good knowledge of Swift, Objective-C or Java & Kotlin
  • For cross-platform development — experience in React Native, Xamarin, etc.
  • Hands-on experience with mobile development SDKs and tools
  • Understanding of mobile platform design & deployment guidelines
  • Wish to optimize app performance and size, network traffic, etc.
  • Close collaboration with UI/UX designers
  • Good knowledge of APIs and software integration techniques
  • Good knowledge of offline apps, caching, etc.

Igor Sheverov

Chief Technical Officer, Partner

"Mobile development needs specific talents. The core advantage (and disadvantage) of a mobile app is that millions of users can install it. One can't compromise the reliability or user-friendliness of an app, as these directly affect the mobile app success."

DevOps Engineers
  • System build & deployment activities
  • System maintenance, hosting management
  • Implementation of CI/CD processes and their automation
  • Software monitoring and emergency response

Igor Sheverov

Chief Technical Officer, Partner

"We do our best to achieve ultimate automation of our development and software delivery processes, maintenance and software updates. Our DevOps experts can stay on the project as full-time members of your software development team or join as required."

QA Engineers
  • Understanding of how to break software
  • Test automation activities
  • Skills of deep-diving into software requirements
  • Thorough reporting and detailed analysis of cross-dependencies in software solutions

Igor Sheverov

Chief Technical Officer, Partner

"There's an opinion among some business leaders that software developers should test their code themselves. We do agree with this statement. However, a full test coverage, as well as efficient QA management are only possible when QA specialists are engaged."

Project Managers
  • General team management activities
  • Progress monitoring, team performance, KPIs, reporting
  • Delivery management (budget and timeline control)
  • Risk identification, development of mitigation strategies
  • Close collaboration with all project stakeholders

Igor Sheverov

Chief Technical Officer, Partner

"Employing a PM will show its best for large teams or in case the development process implies frequent meetings, detailed discussions, harmonizations, etc. to save the time and efforts of the engineers for their immediate duties. Sometimes, a tech lead or a leading analyst may assume the PM's duties."

System Analysts
  • Elaboration and specification of functional and non-functional requirements
  • Ample BA toolkit (role maps, use cases, context charts, decision trees, RTM, etc.)
  • Identification of integration points, specification of the integration part of business features (calls, etc.)
  • Deep understanding of UX design, close work with CX and UX designers, wireframing
  • Description of business processes and business logic
  • Understanding of software architecture (web/mobile app, client-server, etc.)

Igor Sheverov

Chief Technical Officer, Partner

"We advise taking a system analyst onboard in almost 100% of cases, even if you may think that all the details are clear and evident for rendering software development services. A system analyst is an investment that allows us to significantly improve communication processes and dramatically affects software quality. Often, hiring a SA is the crucial condition to deliver solutions on time."

UI/UX Designers
  • Customer experience design (CX)
  • UI flow design, navigation design (user journeys)
  • Logical page structure development
  • Excellent experience in prototyping systems (Figma, Photoshop, etc.)
  • Good understanding of system requirements, good knowledge of the engineering team's needs
  • Emotional bond between the business and its target audience

Igor Sheverov

Chief Technical Officer, Partner

"A good designer is not the one capable to do great visuals. The key skills of the UX/UI design master are system thinking, interface knowledge, and the ability to see design bottlenecks that can show up during the implementation stage."

Business Analysts
  • Subject matter experts for certain business domains
  • Multi-year business experience in the sphere

Igor Sheverov

Chief Technical Officer, Partner

"Qulix has a strong grasp of world-class technologies to build stunning Fintech and banking solutions. Contact us to hire our experts in the areas. If necessary, we can engage outside subject matter experts for a detailed consideration of the client's requirements."

Cooperation Models

We offer three different cooperation models for our clients. Choose the one that suits you best.


We will extend your team with a number of our own resources making them aligned with your existing processes, tools, and approaches. We have a special process that defines the onboarding method to make sure the team extension goes transparently and smoothly. Task management can be on your or on our side.


The additional efficiency of the development process is guaranteed through onboarding tightly-knit engineering teams where team members have worked together on a number of projects and are well aware of each other's strengths and weaknesses. Established internal engineering processes and know-how, alongside deep domain experience, can also bring significant value to your software solutions.

Development Center

We are ready to establish a fully-functional engineering center for you in case you need additional security, separate room space, special HRM/engineering processes, branding, or anything that will make your outsourced project feel like an in-house one. The option is available under special financial conditions and applies to large teams (30+ members).

Agile Process Framework

Our teams apply well-tested and efficient notions and practices of the best custom software development companies, combining Scrum, Kanban, or SAFe in their project activities.

Scrum and Kanban are our standard process frameworks. Generally, we form project teams of 5-8 players (a BA, an architect or a team lead, a PM, developers, testers). For such a scenario, Scrum and Kanban are perfect methodologies to ensure an efficient software development process.

For large-scale projects, especially for those involving product development services, we use the SAFe methodology. To apply SAFe in the right manner, we assign our certified SAFe managers to achieve the best results.

We use

sprints/iterations for delivery planning

daily/weekly standups

team discussions (project progress, bottlenecks, risks, etc.)

dashboards for progress monitoring

regular builds and streamlined CI/CD
