Fifteen years of .NET architecture, Angular frontends, AI integration, and security-first design. Network-Ideas delivers senior-level engineering for organizations that need systems built right the first time.
.NET 10 and ASP.NET Core paired with Angular 21. Architecture through deployment — greenfield builds, API design, and production-hardened frontends.
Production RAG systems, custom MCP server development, prompt architecture, and vector search with pgvector. Practical AI that solves real problems.
HashiCorp Vault integration across secrets engines, penetration testing with OWASP ZAP, CSP nonce architecture, and zero-trust design patterns.
Zero-allocation optimization, cross-language benchmarking against native C++, multi-tier caching strategies. Every millisecond measured and accounted for.
Docker, Terraform, NGINX, and Kubernetes. Bare metal through cloud-native across AWS, Azure, and GCP. Infrastructure as code, always.
ASP.NET Web Forms through modern .NET 10. Database migration, incremental rewrites, and strangler-fig patterns that keep production running.
Full-stack production reference with HashiCorp Vault across four secrets engines, JWT authentication, and Cloudflare Turnstile integration.
RAG + MCP pipeline spanning 13 repositories with 33,000+ embeddings and a custom MCP server exposing four semantic search tools.
Angular 21 SSR with production security hardening, OWASP ZAP penetration testing, and 532+ tests across the application.
17-project .NET solution with automated architecture testing, domain-driven design, and multi-tier caching throughout.
OpenAI integration as a Stripe-gated premium feature with parallel async orchestration and encrypted storage.
Near-native C++ performance in managed C#, evaluating ~180–210 million hands per second through zero-allocation optimization.
John Belthoff has operated as an independent software engineer and architect since 2017. Prior roles include positions at defense-adjacent companies working across multiple security domains, with a prior U.S. Secret Security Clearance and experience in DoD data handling.
Before software, John spent decades as an Emmy Award-winning broadcast and audio engineer in New York City television studios — national broadcasts, live production, real-time systems where failure wasn't an option. That background in production-critical infrastructure and zero-downtime operations directly informs every architecture decision today.
