      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.
