Leobit Executive Interview

We offer our clients both long-term and short-term engagement options for team extension, outstaffing, or outsourcing services.
As a proof of excellence in delivering software product development services, Leobit was recognized as one of the top .NET companies in Ukraine by Clutch, and was listed among top 10 Mobile Application consulting/services companies in 2020 by CIO Advisor. Our company is a Microsoft Gold Certified Partner with a competency in application development.
I’m also proud that for over three years in a row we’ve retained the position of the best IT employer in Lviv, Ukraine. This recognition is based on our employees’ reviews on DOU.ua. We believe this is a natural result of our strong company culture and the values we live by: Smart, Flexible, Open, Efficient, and Caring.
Therefore, I decided to build a company that can make the overall experience of IT outsourcing better and more transparent, as a way to build strong relationships with clients through the values of dedication and trust.
In addition, I noticed that tech companies, especially mobile application startups, are frequently overly focused on the technology side. However, such important aspects as the end-clients’ needs and experience, analysis of the customer business, and plans for software product’s further scaling & growth were sometimes overlooked.
Here at Leobit, we strive to consider every angle and explore every client’s business to identify the right model, the right processes, and the right people that can bring the most value specifically for this customer.
We are extremely flexible. There are tech people of all seniority levels in our team, which is perfect in terms of accommodating a variety of customer requirements for team size and composition, technology stack, project duration, and staffing time. We can offer our clients both full-cycle development or just a single part of product development.
I think that our internal tech mentorship program also adds value to our clients. Even though it was created to foster the professional growth of our engineers, the clients can be sure that there is an experienced developer of the Tech Lead / Architect level behind every project.
We have clients that have stayed with us from the very first days of the company’s existence. And for the projects that are already finished, they recommend us to their friends and industry contacts, so that’s the best proof for me that our customers are satisfied with the services that Leobit provides.
Normally, the full software development life cycle at Leobit begins from the discovery phase. At this stage, our developers gather all requirements to understand the client’s business needs. Our seasoned team decides what tech capabilities are suitable for this specific case and sets realistic time frames. In some cases, the time frame can be determined by the technical side, when some tasks/parts cannot be paralleled and one task can be started only after another one is finished.
For a short-term project with simple, straightforward requirements and all functionality running on a single server, I can assume the back-end and the front-end would demand equal efforts, 50/50.
In the case of a large-scale project, the complexity of the back-end is inevitable. As the number of servers increases, we need to add more tools and processes, i.e. the database, data synchronization, universal API, and so on. As a result, the back-end demands more time and effort. Meanwhile, if the front-end doesn’t need much scaling or adjustments, it requires less time and resources for the development (65% to 35% BE and FE respectively).
However, if you aim to wow the users with an outstanding and complex interface, the front-end could still take up to half of the project resources.
- Project requirements and tech fit. At the very beginning, we identify the unique business and technical requirements that might call for a particular language and framework. The choice might be also influenced by the client's current software ecosystem or their preferences.
- Development and maintenance costs, including the cost of hiring experienced software developers. It would vary based on the technologies they work with. Also, the client should be aware that even after the product has been successfully released, there will always still be a need for updates, fixes, additional features requested by the end-users, and overall improvements. As the business environment changes and the project evolves, the additional maintenance will become a must: to modify, improve, or enhance a software solution.
- Time to market. This factor heavily depends on the technology stack the client chose for the project and the team composition. I would advise making sure the preferred tech stack has enough libraries, etc. to add value to the project; can be seamlessly integrated with third-party solutions; and there is a large enough pool of available developers for current and future needs.
- Security: it is wise to select a framework that is less prone to vulnerabilities, where you can ensure the required level of data security and compliance, if needed.
For web application development, we also advise to use Angular, React or RoR. For native Android platform apps, we recommend Kotlin and Java. For iOS application development (for iPhone, iPad, and other Apple devices), we would suggest Swift and Objective-C.
For a Dedicated Team cooperation model, we calculate expenses based on the number of FTE (full-time employees) and their seniority level.
The dedicated team model is the most attractive for the customers from the pricing standpoint as it allows the customer to extend their organization by a team of highly-skilled professionals, at the best price / quality ratio.
Budgeting on the Time & Materials basis means that we offer hourly rates. For projects that require licenses and materials outside of the standard list, we also calculate the cost of these additional materials that were used (both software and hardware).

Review Summary
Describe your project in brief
Leobit had been tasked with designing and implementing business apps for an IT service company. These apps were expected to transcribe files, manage CO2 credits for the client, and more.
What is it about the company that you appreciate the most?
Overall, we have been and continue to be extremely pleased with Leobit and Kate's work. Above all, their willingness to dig deep into the subject matter allows them to autonomously come up with truly meaningful and well-thought-out solutions that would otherwise require the help of a dedicated system analyst.
We got good advice from their project manager, and all levels of communication were very good.

Mobile App and Web Development for Real Estate Company
What is it about the company that you appreciate the most?
I’ve been impressed by their openness. They always explain what they can and can’t do and why. As we tackle new challenges, they explain how they are going to go about it as well. They listen to what I really want and provide several suggestions based on my input. So far, I’m happy with their work. When we reviewed the app, I identified glitches and assessed how smooth and native the app felt. I found very few issues, but Leobit was quick to resolve them.
What was it about the company that you didn't like which they should do better?
The iOS development seems to lag behind the Android development. Whenever we do demos, the Android seems to be a little more polished and more advanced. Then when we went through the iOS version, I ask them to mirror the Android application.
The service is great and the deliverables are nearly bug-free.
