About Shaif Ahmed
AWS Certified Cloud Practitioner and Oracle Certified Java Backend developer with over 9 years of experience designing and operating large-scale, cloud-native platforms on AWS and GCP. I build high-throughput pipelines and microservices using Java, Spring Boot, Spark, Kafka, BigTable, Cassandra, Redis, and Kubernetes, supporting billions of events per day and millions of API calls per day in production. My work spans multi-region data platforms, real-time streaming, fault-tolerant service architectures, and low-latency distributed caching for revenue-critical systems in retail and financial services. I specialize in distributed system design, data partitioning, schema evolution, idempotency, retries, and reliability engineering, and I routinely own production readiness, observability, and scalability for Tier-1 platforms while partnering cross teams to ship systems that are both fast and correct at scale.
