      We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs. Talentica was brought on board to test and refine the concept from both functional and engineering perspectives, and later to build a Minimum Viable Product (MVP) aligned with the agreed specifications and constraints.

      For several years, the team was composed entirely of Talentica contractors. Since January 2022, I have been directly managing them. The Talentica team handled the admin tooling backend, which included multiple Python Flask services with Postgres and Elasticsearch. These services operated in a service-oriented architecture deployed on Kubernetes, using Istio for service mesh and Spinnaker for deployments.

      Bryan Pratt's Review Sourced from Google

      Mystic Media has been excellent to work with, offered great value, and their expertise and project management has been evident throughout the development process. We hired Mystic to take an idea and concept drawings through UI/UX and graphic design, programming and development, all the way to the market. They have met or exceeded all milestones, even with significant additions to scope along the way. We're currently in beta testing before release, and we are very satisfied with the entire experience. Mystic has earned my unqualified endorsement for anyone looking to develop their first app with them, as we have done.

      Software Development Review from Liudmyla Osadcha

      From wireframes to production release, INC4 built all of our user-facing products. The initial concept validation, design, and prototyping was created by our organization, but INC4 helped us to refine our interfaces and ensure the application logic was solid. As a result, we have collectively built and released four interconnected user-facing software applications that all are integrated with blockchain technology.This suite of applications is integral to our business. INC4 made our software products world-class in terms of usability, functionality, and reliability. Working with INC4 ensured our products were built and released on time and on budget.INC4 has a multitude of world-class project managers that make our work easy and fun. The project manager's excellence in communication, technical mastery, and expectation management ensure our project's delivery is of minimal concern. Delivery roadmaps are always communicated clearly and met without fail. The only time deadlines shift are when we (the clients) introduce new development criteria or features that take more time to build. However, even when this happens, the INC4 team are unflinchingly eager to accommodate our changes and adjust delivery processes accordingly. INC4 is efficient, agile, and thorough.The most impressive aspect of INC4 is how they seek to become truly invested in the development and success of each project they work on. They go beyond what is typically expected in this relationship, and are true partners who want to see our company grow. This provides a deep sense of security and trust for us as their clients.We never have to even consider INC4 taking shortcuts during the development journey because that kind of behavior is so opposed to their core organizational ethics. No matter what obstacles this organization faces, they adjust their development capacity accordingly and keep working with consistency & happy attitudes.
