Software Development

We provide a solution for Tissue Engineering researchers throughout the world. The solution consists of a high-end 3D bio-printer capable of handling a wide range of biomaterials and BioInks, consumables and a software solution for designing the desired print. To be able to offer the best quality, we needed to increase our internal software development team and were looking to extend it with experts in C# .NET development who could join and integrate a team. The CSHARK team participate in building the front- and backend of the system. The knowledge brought by CSHARK boosted the development rate and quality to an extremely high-level. The code quality increased drastically by reaching an 80% code coverage in just a few months of work, while the amount of feature implemented more than doubled since the arrival of the CSHARK development team. Throughout the different internal reviews that we often have, a unanimous feeling of wonder at the development has been expressed. The most impressive thing about CSHARK is their ability to react quickly and efficiently. When requirements changed, the developers were quick to adapt and implement the changes, and the managers were also quick to propose solutions to project management challenges.

Software Development

They collaborated with our team to create a product that complied with our needs and made future maintenance easy. As a solution, they designed a trifold database concept. Through this database, we can quickly migrate to an elastic environment, which is required for predictive maintenance, machine learning and other future tech. They also designed a microservices system using Docker that would enable data exchanges through the cloud or in on-premise deployments. We’ve made some ergonomic improvements that have enhanced UX and workflows. Overall, the platform’s architecture exceeded our expectations. They are exceptionally reliable. However, they aren’t afraid to suggest new ways to approach challenges. They’re willing to adapt to our requirements, but they won’t continue to work on something that won’t be effective. I’ve been in the business for 25 years, and I’ve never worked with a company with this level of professionalism.

HTP J-1 Visa Programs places exchange visitors from all over the world in internships, training programs and teaching opportunities in the US. We carefully screen exchange visitors, interview them, review documents and make sure they meet all regulatory requirements. We help them prepare for their stay in the US, and provide ongoing support while they’re here. CSHARK developed custom software using C#. The software includes a number of different user modules, including an admin module that has various user dashboards and registration wizards. It’s extremely pleasant to work with CSHARK team, all the way from initial contact with CEO, through business development and onboarding. Excellent transition and knowledge transfer process from the previous developer. CSHARK has strong, detailed operating processes for managing the project. This includes a heavy focus on QA. Our strong project manager ensures that the project stays on track. The developers are detailed, knowledgeable and think three steps ahead. The impact of the engagement is the accelerated progress of project.
