WHY ORGANIZATIONS CHOOSE US
Discover the cutting-edge benefits our clients enjoy from the global Toptal network.
Authentia partners with Toptal to revolutionize gem tracing with a first-of-its-kind blockchain solution.
Challenge: Bruno Scarselli, a third-generation diamond dealer, needed to create a platform that could issue cryptographic titles of authenticity, origin, and ownership for gems. He was unsure of the technical requirements, particularly around blockchain development, and faced a complex path to execution.
Solution: The team followed a rigorous project management timeline focused on rapidly delivering Scarselli’s most needed features, delivering a working MVP in just 14 weeks. The platform leverages a React/Node.js infrastructure to support an Ethereum-based blockchain protocol. The system uses a robust AWS infrastructure, including IAM, S3, CloudFront, Lambda, Aurora Serverless, KMS, SES, CloudFormation, EKS, and EC2 to ensure scalable, secure, and efficient service delivery.
Outcome: Thanks to the team’s rapid execution, Scarselli attracted his first 50 diamond-industry customers mere months after ideating on his product vision. For technology startups, this rapid speed to market is critical for both short- and long-term success.
This collaboration has not only streamlined our operations, but partnering with Toptal has given life to entirely new industry standards for transparency.
