Distributed Rate Limiter Service
June 17, 2026 – Present
Built a standalone rate-limiting microservice implementing sliding window and token bucket algorithms, consumable by any backend service via REST. Used Redis for distributed counter storage, ensuring accurate rate enforcement across multiple instances without a single point of failure. Designed a pluggable rule engine allowing per-client, per-endpoint rate limit configuration dynamically without redeployment.

Designed an event-driven notification service handling email, push, and SMS delivery using RabbitMQ for asynchronous message processing. Implemented retry logic with exponential backoff and dead-letter queues to guarantee at-least-once delivery with zero message loss. Built a delivery tracking system in MongoDB enabling real-time visibility into notification success and failure rates across all channels.
Backend Observability Dashboard
June 17, 2026 – Present
Architected a centralized logging and monitoring system to track API performance, error rates, and overall system health in real time. Implemented structured JSON logging across all services, enabling efficient querying, filtering, and alerting via OpenSearch. Built Kibana dashboards visualizing key SLA metrics – P95 latency, error rate, and throughput – actively used by the team for incident response.
