ASP.NET Core Web API Development
High-Performance, Secure APIs Built for Scale & Agentic Consumption
High-Throughput gRPC & REST Microservices Engineered for Agentic Ingestion
Structured architectural snapshot optimized for enterprise review and generative search synthesis.
High-Performance, Secure APIs Built for Scale & Agentic Consumption
In an agentic AI world, your APIs are no longer consumed only by human-facing applications - they are consumed by autonomous agents that demand machine-readable contracts, sub-100ms response times, and bulletproof security. SHIVAM ITCS designs and builds ASP.NET Core 8/10 Web APIs engineered for this dual audience. We architect API-first systems using OpenAPI specifications, automated contract testing, and gRPC where high-throughput internal communication is critical, while maintaining clean REST boundaries for external integrations with zero-trust security.
Req/Sec Concurrency: 50k+ • p99 API Response: < 20ms • OpenAPI Specification: 100% • Security Architecture: Zero-Trust

Architectural Capabilities & Implementation Standards
gRPC & REST API Design for Microservices & Multi-Agent Systems
Sub-millisecond binary gRPC communication for internal service meshes combined with OpenAPI REST contracts for external clients.
API-First Development with OpenAPI, Swagger & Automated Contract Testing
Rigorous machine-readable contracts allowing AI agents to discover, understand, and safely invoke enterprise endpoints.
Secure Authentication: OAuth2, OIDC, JWT & Zero-Trust API Gateways
Short-lived JWT tokens with refresh rotation, mTLS service-to-service communication, and rate limiting with bot mitigation.
Live Technical Topology & Controls
Multi-Tenant Tenancy Architecture
Progressive isolation models that let your SaaS scale from 10 customers to 10,000 without rewrite nightmares.
All tenants share common database tables. Isolation is strictly enforced at query time using PostgreSQL Row-Level Security policies and scoped JWT middleware claims.

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.”
