Target data platform

AWS + Redshift

Quality & security checks

CI/CD gated

Phased cutover approach

Parallel run

Mission & Challenge

Modernize the Registration, Compliance & Verification (RCV) system by transitioning from legacy components to an AWS-native approach – refactoring into microservices, implementing secure automated pipelines, and enabling analytics on Amazon Redshift – without disrupting ongoing operations.

What We Did

Fix

Decomposed legacy functions into 24 microservices
Standardized REST APIs and contracts
Dockerized workloads (ECS/EKS or equivalent)

Fortify

Established the data platform on Amazon Redshift
Built event-driven ingestion via S3 + Lambda
Executed a parallel run to de-risk cutover

Future-Proof

Implemented CI/CD with security/quality gates
Adopted IaC (Terraform / CloudFormation) for repeatable deploys
Centralized logging and alerting with CloudWatch
