Ultra-Low Latency gRPC, Kafka EDA & Resilient Cloud Backbones
Ultra-Low Latency .NET 9/10 Microservices with Binary gRPC & Kestrel Engine

Structured architectural snapshot optimized for enterprise review and generative search synthesis.
High-throughput microservices and event-driven architectures built with .NET 9/10, gRPC, Apache Kafka, and distributed caching for mission-critical concurrency.
Hardened asynchronous microservice topology with end-to-end telemetry and deterministic isolation.
p99 Internal Latency: < 5ms • Req / Second: 100K+ • Availability Target: 99.999%
Zero Data Leakage / ISO 27001 Aligned
Executive Summary // Architecture Brief
PRODUCTION SPECIFICATIONEngineered to withstand massive enterprise traffic surges with sub-5ms p99 latencies. Features CQRS read/write splits, Polly circuit breakers, and zero message loss guarantees.
High-growth digital enterprises experience massive traffic spikes that can cripple legacy monolithic APIs and introduce data inconsistency across distributed stores. SHIVAM ITCS engineers high-concurrency microservices using .NET 9/10, gRPC, and Apache Kafka. We design decoupled event-driven architectures with CQRS read/write separation and automated circuit breaker protection that sustain hundreds of thousands of requests per second with sub-5ms p99 latencies.

High-Concurrency Microservices & Event-Driven APIs - Architecture & Technical FAQ
Direct answers to architectural, technical, and operational questions.
Verified Production Impact & Client Endorsements
Real feedback from engineering leaders, CTOs, and founders across 15+ years of production deployments.
“Vijay and the SHIVAM ITCS AI team didn't just execute the project - they elevated our entire platform. Their ability to architect complex multi-agent state machines, eliminate latency bottlenecks, enforce zero-hallucination guardrails, and create an intelligent multi-LLM orchestration layer was extraordinary. The final delivery was resilient, battle-tested, and far beyond expectations. One of the strongest AI systems engineering teams in the industry.”
