      Software Development Review from Michael S.

      We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

      Cross-Platform Review from Awital Ifrah

      Masa came in with a pretty loose idea and AppMakers helped turn it into something solid. What I appreciated most is they didn't overcomplicate it or try to make it into some giant monster platform. They listened, asked smart questions, and helped us focus on what would actually matter for alumni and current participants. The end result felt thoughtful and realistic. I'd definitely work with them again.

      Startup Review from Moishi Stern

      We create live events. We wanted a site that shows what we do without making people dig. AppMakers listened, trimmed the fluff, and gave us pages that read fast and look good on a phone. The quote form asks the right things and our team can update galleries without calling a developer. They stayed on schedule and answered messages the same day. The whole process was calm and clear. We already see better inquiries. It feels like a real upgrade, even before the full rebuild.

      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.
