PROJECTS

01 — Order Orchestration

ORDERFLOW

Saga-pattern microservice coordinating multi-step order workflows across bounded contexts. Transactional outbox for guaranteed message delivery, idempotency keys for exactly-once processing under partial failure.

Outbox + Idempotency
Transport
Apache Kafka
Each service publishes domain events to Kafka topics. The outbox table guarantees events are never lost even when the broker is temporarily unavailable — written atomically with the local transaction.
02 — Real-Time Messaging

NEXUS

WebSocket-based collaborative chat with Kafka fan-out for horizontal scaling. STOMP protocol, topic routing, persistent message history.

Kafka Fan-Out
Multi-broker Kafka fan-out enables thousands of concurrent WebSocket sessions without a coordination bottleneck.
03 — AI-Augmented Gateway

GATEAI

Reverse proxy in Go with JWT auth, Redis token-bucket rate limiting, and async anomaly detection via Gemini API. Sub-millisecond routing on standard traffic paths.
