Project: CIG Canonical API Platform (partyApi, claimsApi, policyApi, exposureApi). The CIG (Canonical Insurance Gateway) Platform is a cloud-native microservices ecosystem designed to provide a normalized and unified API layer between Guidewire ClaimCenter and downstream enterprise systems. The platform exposes domain-driven canonical APIs for claims, parties, policies, exposures, incidents, and service requests, enabling seamless integration, standardized data access, and real-time insurance claim processing.

The platform follows an API-first and contract-driven architecture using OpenAPI specifications, ensuring consistency, scalability, and maintainability across services. Each microservice acts as a stateless façade over Guidewire APIs, transforming and normalizing data for middleware and external consumer applications.

Client: Standard Chartered Bank – SCB.

Project: GNSRT (Global Name Screening - Real Time).

Global Name

Screening (GNS) will provide functionality to perform periodic name screening, On-Demand Batch Name Screening and Alert management. Name screening applications are used to match customer and related party names against Sanctions and Due Diligence (PEP +Adverse Media) lists to identify any sanctioned or high risk individuals or entities that require further investigation or enhanced due diligence. Customer screening currently takes place at two distinct stages in the customer life cycle: First, the Account Opening Check (AOC) is performed in near real-time prior to account opening. Second, the Customer Match Report (CMR) periodically rescreens customer against the watch lists to ensure that existing customer has not been added to watch list.

Global Name Screening

Real-time (GNS RT) aims to provide bank with solution to screen new to Bank customers and related parties against watch list in real-time. The GNSRT Endeavour's to replace current on-boarding system (Detica AOC) with FircoSoft Screen & Keep (FSK) on boarding screening solution.
