Transform VB6, ASP.NET WebForms & WCF into .NET 10 Microservices
Legacy systems are not just technical debt - they are competitive anchors. SHIVAM ITCS specializes in enterprise .NET modernization that migrates VB6, ASP.NET WebForms, WCF, and monolithic .NET Framework applications to cloud-native .NET 10 microservices without the downtime and disruption that kill traditional rewrite projects. Our approach follows the proven 7 R's framework, utilizing automated dependency discovery and the Strangler Pattern to incrementally replace legacy modules while keeping the system operational. With 20+ years of Microsoft stack expertise and co-founder Ajay Paliwal's deep architectural leadership, SHIVAM ITCS turns legacy liabilities into modern, maintainable, scalable assets.
Production Downtime: Zero • Throughput Speedup: 4.8x • Infrastructure Spend: -58% • Microsoft Stack Heritage: 20+ Yrs

Architectural Capabilities & Implementation Standards
The 7 R's of Modernization: Retire, Rehost, Replatform, Refactor, Rebuild
We do not default to risky rebuilds when refactoring or replatforming delivers 80% of enterprise value at 30% of risk.
Strangler Pattern Migration with Zero Production Downtime
Incrementally strangle legacy modules via API gateways and shadow routing, keeping core operations live without a single second of downtime.
AI-Assisted Code Transformation & Automated Dependency Mapping
Surface the 30-40% of hidden database links and undocumented rules using AI-assisted code parsing, generating parallel regression test suites.
Live Technical Topology & Controls
Security & Regulatory Topology
Production-validated compliance architecture designed for high-concurrency regulated environments.
Core Architectural Safeguards (HIPAA & NABH (HealthTech))
Encrypted PostgreSQL tablespace & blob store with rotating KMS keys.
Every chart access and prescription modification logged with user ID & timestamp.
Strict segregation between doctors, nurses, billing, and lab staff.
Zero patient data sent to public cloud LLM APIs; runs on local Ollama/vLLM.
Guarantees PHI data protection, automated clinical access audits, and zero-leakage local AI processing for hospitals and telehealth platforms.
Core Ecosystem Technologies
100% Type-Safe & BenchmarkedEnterprise Engineering Endorsements & Track Record
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.”
