PaySecure Payment Platform

A financial services company required a secure, compliant processing platform to serve merchants directly rather than through third-party providers.

Compliance requirements, sub-second authorisation latency and fraud patterns that change weekly — all with zero tolerance for data loss.

A gateway with tokenised card handling, an event-sourced ledger, a machine-learning fraud model scored in real time and a merchant portal for onboarding and settlement.

Merchant onboarding was cut from a multi-day document exchange to a guided flow that most merchants complete in one sitting.

Event streaming with Kafka, isolated services for tokenisation and scoring, PostgreSQL ledgers with strict auditing, and infrastructure designed for the compliance audit from the start.

Security reviews at every milestone, chaos testing on the ledger, and staged rollout by merchant segment.
