Pleenk. Secure Payments Platform

Pleenk set out to develop a payment platform that prioritizes speed, security and operational transparency. In a market where payment failures, fraud risks and scalability limitations can significantly affect revenue, the goal was to create a system that reliably processes high volumes of transactions while adhering to strict security standards.

The team aimed to:

• Process payments and settlements in real time with low latency.
• Provide built-in fraud detection and risk monitoring.
• Offer secure APIs for merchants and digital platforms.
• Ensure compliance readiness and auditability across all transactions.

Pleenk needed a technology partner with a strong background in developing high-load financial systems that meet stringent reliability and security standards. Pharos Production offered extensive experience with event-driven architectures, real-time data processing and cloud infrastructure. This expertise enabled them to build a payment platform that can scale globally while ensuring consistent performance and reliability.

The backend is built on Java and Spring Boot, providing a stable, extensible foundation for payment workflows, transaction processing and API services. Apache Kafka streams payment events and state changes, while Apache Flink processes these streams in real time to handle validations, risk assessments and transaction status updates. This architecture ensures that payments are processed accurately and without delay.

Pleenk offers a modern web interface built with React and Next.js. Merchants can access dashboards for transaction monitoring, reporting and reconciliation, while administrators manage risk controls and system configuration through secure web tools.

PostgreSQL and Apache Cassandra store transactional data, account states and audit logs at scale. Redis provides low-latency caching for active sessions and authorization data. Apache Pinot supports real-time analytics for transaction monitoring and performance metrics. The entire platform runs on Kubernetes with Istio for traffic management and is deployed on AWS to ensure elasticity, high availability and fault tolerance.

Pleenk processes transactions in real time with integrated validation and monitoring, ensuring a fast user experience and accurate management of financial state.

The platform continuously analyzes transaction patterns and events to detect anomalies and reduce fraud risk.

Well-documented, secure APIs enable businesses to integrate Pleenk payments into their web and mobile applications easily.

Pleenk provides a reliable payment infrastructure that can handle high transaction volumes without sacrificing service quality.

Real-time monitoring and comprehensive audit trails enable businesses to maintain control, minimize risk and meet compliance obligations.

With its cloud-native, event-driven design, Pleenk scales seamlessly across regions, supporting business expansion and accommodating increasing transaction volumes.
