The Challenge

Verifying candidates is slow, manual, and costly

Hiring processes face a recurring and costly problem: verifying candidate information. Studies indicate that approximately 57% of resumes contain false or incomplete data, forcing recruitment teams to dedicate significant time and resources to manual checks.

A group of consultants with backgrounds at organizations like Accenture, PwC, and IBM identified this gap and set out to invert the logic: allow candidates to pre-validate their credentials before entering selection processes.

What the platform had to be

  • Secure and scalable
  • Integrated with multiple data sources
  • Able to run automated verifications without compromising sensitive data protection
“BIX has been an excellent partner, attentive to our needs and fundamental in building functional software based on a robust architecture that prioritizes security, scalability, and cost-effectiveness. They brought in the right technical experts and their flexibility in adapting to changing requirements has been invaluable.”
Charles Blechman, Chief Technology Officer, Valid8

The Solution

A microservices platform on AWS

BIX Tecnologia developed a comprehensive solution based on a microservices architecture on Amazon Web Services (AWS):

  • Frontend: Next.js
  • Backend: FastAPI (Python)
  • Database: DynamoDB
  • Infrastructure: provisioned via Terraform and hosted on AWS Amplify and ECS Fargate

Ten independent microservices

Each microservice has a defined responsibility: identity and document verification, work authorization, employment history, educational validation, criminal records, and protection of sensitive data (SSN, passport, driver's license). All sensitive data is stored in a private subnet with encryption via AWS KMS.

Integrations, security, and quality

  • Integrations: AU10TIX for facial recognition and real-time ID validation; InfoMart for criminal, educational, and employment background checks.
  • Security: authentication managed by Auth0 (with MFA), protected by AWS WAF and AWS Shield, with continuous monitoring via Snyk and Sentry.
  • Quality Assurance: CI/CD pipelines including unit tests (Jest), end-to-end tests (Cypress), load testing (JMeter), and accessibility checks (Axe).

Results

Verified profiles, faster and safer hiring

Verification

Before: Recruitment teams dedicate significant time and resources to manual checks

After: Candidates validate their information before entering hiring cycles, creating verified profiles for recruiters

Hiring decisions

Before: Decisions exposed to false or incomplete resume data

After: HR teams decide faster and more securely, with more reliable data

  • Reduced operational costs for HR teams
  • Expanded BIX Tecnologia's expertise in Event-Driven Architecture and cloud security, in an international collaboration involving teams in Brazil, the United States, and Australia
