Our team always tracks CPA/CPC/LTV from the first day and knows how to climb to the top of search results. We deliver comprehensive web development services with a clear development process.

MVP Development

The OQTACORE team has developed more than 50 MVPs, and we know the importance of building fast. We build MVPs that have basic functionality to better work on the idea, spot specific needs within a target audience, test the Client’s market fit, and get to the seed round as quickly as possible. It increases the chances to get investment because fast startups are always preferred by investors.

Ecommerce & Marketplace Development

Our team follows the latest industry trends to build custom platforms for buying and selling products online. We do not just build marketplaces, but we also know what makes the gears turn under the hood. OQTACORE understands how to automate all business processes: order management, content management, price management, warehouse management, logistics, billing, and many more. We can design most of the modules of a marketplace on our own, while the Client concentrates on the creative parts of the business.

Enterprise Development

Our team has developed and implemented 3 large software platforms with 20k+ users each, which are still used by top companies. We fully understand the importance of product acceptance by employees of the Client, so we work individually with key users (regular staff, supervisors, C-level management): we collect business requirements, analyze them, get approval from the Client, and implement them. The main priorities are software performance, compliance with established business practices, security from external and internal attacks and threats.

Steps of software development with OQTACORE

Schedule a call

Signing NDA

Either before the first consultation or immediately after it, we will sign an NDA so that we can ask and find out details that are important for the project, which may constitute a trade secret.

Initial consultation

At the initial consultation, you can get to know the leaders of our team, and we, in turn, will get to know your product, its current needs, and goals.

In-depth study of your business and market research

We conduct market research, analyze trends and best practices. Then we come up with solutions and decisions that will empower your product for success. You can choose to accept or not accept each individual proposition.

Commercial offer

Based on your vision and decisions taken, we estimate the scope of work, the timing, and the cost, and come up with a commercial offer.


If you are satisfied with our offer, we will ask for a 33% prepayment and get down to work.


We usually break product development work into two-week sprints that minimize the amount of up-front planning. We always prioritize items in the backlog at the beginning of each sprint. Thereafter, our development team starts building the required functionality, which is then tested against bugs by our QA engineers before release.

OQTACORE was recommended by one of our partner companies. We worked with many development companies for comparison. The best part of a partnership with the OQTACORE team is that in addition to exceptional quality specialists, the founders Dmitriy and Saveliy, take care of all the details and let me focus on strategic thinking. I give them the main direction and they tackle how the product should look and feel. The quality of their specialists and the price that we are paying for that quality is fair.

The OQTACORE team built for me a web phycological freelance platform that brings together psychologists and clients. On this platform, they can call each other, chat, schedule appointments, and so on. This is a huge project that we are working on right now. OQTACORE shows a very high level of quality. I really like the management - we are always on the same page. We often have phone calls on weekends if I need them. We started small, and it is important that OQTACORE has used a scalable architecture for future growth since we expect hundreds of thousands of users in the coming years. I am also planning to create an application with them for iOS and Android.

The OQTACORE team has done a great job, and their work has received positive feedback from our investors and third-party partners. The team is very professional and has shown a good quality of development. The most impressive has been the flexibility they have shown us during the project. Dmitriy and Saveliy truly invested in our project, so we call them our business partners. They believe in what we’re trying to accomplish.

The OQTACORE team built for me a cloud mining platform. This is the second project that we are conducting together with OQTACORE. The team has done miracles in terms of the speed of developing the first working MVP. After two months, we have seen the first registrations of real users and the first revenue. An important detail - the MVP was built so that it could be scaled and extended upon with new functionality to become a fully functional enterprise-level system without refactoring.

OQTACORE proved to be an excellent value for the money. Our company has two separate offices, one in the USA and one in Hong Kong. We had our internal platform for communication between offices, but it was simple without any useful features. We decided that we need an intranet platform like Facebook where we could share our information and keep everyone across the globe involved. Saveliy at OQTACORE took our problem very seriously, came up with all kinds of features that we needed, and it took just 10 months to get a working product that we use now. I am pretty sure that we will contact OQTACORE again!

Now we have a platform that will let us expand our work more quickly than what would have been previously possible.
