•Designed and implemented distributed task processing pipelines capable of handling millions of asynchronous jobs per week, improving system throughput and reliability •Built event-driven architectures using message brokers (RabbitMQ, Kafka, AWS SNS/ SQS), enabling loosely coupled services and scalable data processing workflows •Developed high-concurrency systems leveraging async programming (Python asyncio, FastAPI) to efficiently manage I/ O-bound workloads •Implemented horizontal scaling strategies using load balancing, auto-scaling groups, and stateless service design to support traffic spikes and ensure system resilience •Designed fault-tolerant systems with retry mechanisms, circuit breakers, and graceful degradation strategies to ensure high availability •Optimized API performance and latency through caching strategies (Redis), query tuning, and response compression, improving system efficiency under heavy load •Built and maintained data pipelines and processing workflows for large-scale data ingestion, transformation, and storage •Collaborated with engineering and product teams to define and implement scalable system design patterns, improving development velocity and system maintainability •Led backend performance tuning initiatives, identifying bottlenecks through profiling and monitoring tools and improving system response times significantly •Developed secure and scalable authentication and authorization systems, integrating OAuth 2.0, JWT, and fine-grained RBAC policies •Automated infrastructure provisioning using Infrastructure as Code (Terraform / CloudFormation) to ensure reproducibility and environment consistency •Implemented observability best practices, including structured logging, distributed tracing, and real-time monitoring using Prometheus, Grafana, and ELK stack •Designed systems with idempotency, data consistency, and eventual consistency models, critical for distributed and event-driven architectures
