Nextcheck, the KYC Platform

Pharos Production partnered with Nextcheck to replace outdated, manual onboarding with a secure, automated KYC/AML platform. Built on AWS, Kubernetes, Istio, Elixir, RabbitMQ, PostgreSQL and NextJS, the platform provides real-time biometric and document verification, risk assessment and compliance reporting.

  1. The Challenge: Replacing Legacy KYC with a Scalable Platform

The client’s existing KYC infrastructure was built on outdated legacy systems that could not keep pace with regulatory changes or growing transaction volumes. Manual onboarding workflows frustrated customers and created compliance blind spots. Specifically, the system faced:

  • Average onboarding time exceeding 48 hours due to manual document review
    • Legacy architecture unable to meet updated AML directives across multiple jurisdictions
    • No horizontal scaling capability, limiting throughput to under 500 verifications per day

These constraints were costing the client customers and exposing the business to regulatory risk.

  1. Objectives

Our goal is to develop a next-generation KYC solution that:

  • Automates document and biometric verification
    • Complies with international standards (EU AML directives, FATF and local regulations)
    • Reduces onboarding time from days to minutes
    • Scales globally with cloud-native infrastructure

We aim to deliver a secure, regulation-ready platform that is simple for users and powerful for compliance teams.

  1. Our Engineering Approach

We delivered the project end-to-end with a team of backend engineers, frontend specialists and DevOps architects. Our approach included:

  • Cloud-first architecture designed for high availability and fault tolerance from day one
    • Frontend and backend optimized specifically for compliance-heavy workflows
    • Third-party integrations with biometric verification, document scanning and sanctions list providers
    • Real-time admin dashboards with automated compliance reporting
    • Continuous security testing and performance optimization throughout the delivery cycle

This methodology enabled Nextcheck to launch a modern, scalable KYC platform built for global growth.

  1. Technology Stack

A contemporary, enterprise-grade stack was chosen to ensure reliability and high performance:

  • Backend: Java, Spring Boot, Microservices, Kafka

  • Frontend: Next.js, React

  • Infrastructure: AWS, Kubernetes, Relational & NoSQL databases

  • Tools: CI/CD pipelines, observability, GDPR/AML security frameworks

This well-designed foundation supports rapid growth and regulatory compliance flexibility.

  1. How We Transformed KYC Performance

We engineered the platform to turn compliance from a bottleneck into a competitive advantage:

  • We reduced document verification time from 48 hours to under 15 minutes
    • Our OCR pipeline achieves 99.8% accuracy across 40+ document types
    • We delivered 5,000+ verifications per day capacity with sub-3-second response times

  1. How We Reduced Manual Compliance Work by 70%

  • We automated 70% of manual review tasks through intelligent document classification and risk scoring
    • Our team built configurable rule engines that adapt to 12+ jurisdictions without code changes
    • We integrated real-time sanctions screening that processes watchlist updates in under 60 seconds

  1. How We Accelerated Client Growth Through Faster Onboarding

  • We reduced sign-up abandonment by 45% through a streamlined verification flow that takes under 2 minutes
    • We built a white-label API that our client uses to onboard B2B partners in days instead of weeks
    • Our platform now supports 100% regulatory compliance across all target markets with zero audit failures

Project Outcome

Automated KYC verification for 5,000+ documents daily with 99.8% accuracy
