Software Development Review from Anonymous
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.

Software Development Review from Anonymous
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.

Software Development Review from Jimmy Carlisle
We needed an in-depth upgrade of the legacy auditing system. We chose Itransition because they swiftly responded to our project requirements and had relevant expertise. The team helped us decide on the solution’s tech stack and designed the new architecture, migrated legacy data, developed new features, and customized the software with extensions. We got a powerful and user-friendly auditing system and were very impressed with the Itransition’s dedication and attention to detail.

Software Development Review from Shoshana Parker
We enjoyed working with Itransition. We needed a solution for transferring health records from our EHR into the data warehouse without losses. We chose Itransition for their experience, portfolio, and past clients’ references, and the team fully met our expectations. They built a custom ETL tool that increased our visibility into clinical data and helped us spot inefficiencies in patient workflows. Needless to say, they also delivered it on time and budget.

John Andesilich's Review Sourced from Google
I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.
