Leo-Source provides architectural services for both new and existing systems. For existing systems we can do architecture review, identify bottlenecks, and come up with proposed changes. When designing systems we follow the latest technologies and trends, ensuring at the same time that the design conforms to your organization's established technology standards and practices. We will work with you to document system requirements and provide analysis and effort estimation in order to help you gain a sense of what it will take to fully realize a solution. Leo-Source specialists can create detailed UML or similar models that fully describe a system. Models can be delivered at any desired level of detail, from high-level logical organization to detailed class-level or method-level design. We can also evaluate existing system designs for opportunities to simplify or enhance systems.


Leo-Source follows Agile software development methodologies. We live in a constantly changing world. A business decision that worked perfectly in the past may not be good in the present. We thoroughly test every iteration to ensure that our services meet the client`s exact needs at a given moment and to promptly respond to changes in the environment, business logic, or higher priorities. We use commonly used tracking tools such as Redmine, PivotalTracker, Asana, Basecamp, Microsoft TFS and several others.


Here at Leo-Source, we value the importance of quality of the final product or service we provide. Every activity we do, every product we deliver, and every service we offer are checked thoroughly. We have a great team of quality assurance engineers with working experience of one year to five. Leo-Source provides major types of software testing, including manual, automated, semi-automated, functional, load, stress, security, usability testing and other types.


The keystone of each project is a clearly defined scope, which is mostly defined through continuous business analysis for each product. Our team has extensive experience of collaboratively defining the most suitable solution for each particular use case of a final product. Business analysis will be performed for your project as an iterative process. As the first step, we will review and discuss with you all your requirements to form a vision, goals, and use cases for the product. Then project scope will be defined (adjusted), and the main priorities of development will be established. Next, the project plan will be adjusted to meet the most recent requirements. During the development of the project, we will track progress and manage updates. We take great care to thoroughly analyze your requirements to offer you the best possible solutions.


Effective project management can help you achieve even the most demanding objectives. Offering IT project management services, we will help you save a great deal of time. Our project managers will handle the most difficult part of the software development process: coordinating work on implementing your idea. Our managers understand the importance of effective communication and visibility. With Leo-Source, you always know where your project is at, always get your emails promptly replied to, and can always count on high quality. Here is a list of professional project management services provided by Leo-Source:

    • Creating and maintaining project documentation
    • Organizing and conducting team building and evaluation

We provide our clients with pixel perfect HTML. We can use latest technologies when developing HTML such as jade, scss, haml. Our team is experienced in creating CMS themes, email templates, responsive and mobile compatibility, and auditing of existing markup. The only input we need for the conversion is the source files (a .psd, .ai, .pdf, or .png file of the HTML) or a link to the existing site. As a result, you will get markup packages and a test report from our team. We can also provide you with a detailed audit description, recommendations, and any other information that is needed for your project.


Nowadays marketologists can not imagine a successful marketing email campaign without mobile and social media. Yet, not all emails are displayed equally well in various email services, browsers, on different devices and operation systems. The principles of designing emails and doing responsive or flexible email markup development as well as testing are completely different from those of web design and development. Our team possesses the necessary skills and expertise to design custom emails, email templates, convert PSDs provided by customers into responsive markup and thorough testing of the emails created for you and your customers.

Engagement Models


We handle your project requests by assigning appropriate specialists and charge you for the actual time spent.

This way the project is handled mostly on our side under our company's supervision and you are expected to provide overall direction, timely feedback and information on priorities changes (if any), while we do most of the heavy lifting for you.

To implement smooth processes a Project Manager on our side is assigned to every project and account and is a central point of communication. A Project Manager's job is to foresee and predict problems rather than just solve existing issues, also be responsible for estimation, planning, reporting, tracking, demos and presentations, feedback exchange, and generally making sure the progress is being made in the correct direction and everything functions efficiently.


We provide a seamless virtual extension to your in-house development staff by dedicating specialists on our side solely to your projects for 8 hours a day and 40 hours a week on continuous basis for ongoing engagement. Our specialists collaborate with your team on a daily basis via various media channels, receive priorities, instructions and directions, participate in regular status updates, and contributing to your overall success.

You maintain full control over the dedicated team, and we can provide additional supervision of the team for greater efficiency - where a Project Manager on our side oversees successful collaborations or acts as an integral part of your management scheme.

You can start with a single professional and then expand to a full-fledged development center located at Leo-Source over time by involving specialists in other technologies and directions.
