Sample project to explain about resilient patterns for integration distributed services
Splitr is a lightweight, Spring Boot-based library designed to implement the Request-Response pattern over Kafka. It allows microservices to execute synchronous, typed queries across distributed boundaries while maintaining idempotency and high performance.
Quondam is a highly available microservice that helps to track idempotence keys in an effort to make things happen 'only once'
Document Registry with gRPC API, Versioning, Tracing and Idempotency
Idempotency library for Java
Scalable Distributed Ledger System implementing Hexagonal Architecture & DDD. Features optimistic locking, idempotent financial transactions, and double-entry bookkeeping using Java 21, Spring Boot 3, Kafka, and PostgreSQL.
A high-performance Payment Gateway API built with Spring Boot 3 to solve concurrency race conditions and guarantee idempotency using Redis and PostgreSQL Pessimistic Locking.
business center handles all logic operations from the user, validates and checks request, before publishing intent to account center for transfer and top up requests, and listening to result to send a webhook request for frontend. Also calls user center for password verification and JWT token validation
A saga-orchestrated microservices banking MVP designed to ensure consistency, fault tolerance, and correctness in distributed financial workflows.
A Spring Boot backend that demonstrates offline UPI payments routed through a simulated Bluetooth mesh network. Imagine you're in a basement with no connectivity
Transaction orchestration microservice for handling idempotent money transfers between accounts in a distributed payment platform.
A Spring Boot event ingestion API with idempotent writes, JSONB payload storage, and Liquibase-managed schema migrations, built to model real-world backend reliability patterns.
High-throughput distributed payment system built with Java and Kafka, implementing idempotency, outbox pattern, and fraud detection via event-driven architecture.
