I have a great passion for solving problems and can help people with various programming languages, databases, information systems, software related projects.
I help developers and product teams solve difficult .NET backend problems, improve architecture, and turn prototypes into secure, production-ready applications.
I have 14+ years of software engineering experience, including technical leadership, ASP.NET Core, C#, EF Core, distributed systems, Clean Architecture, DDD, cloud deployment, and AI/LLM integration.
I can help with:
• Debugging complex .NET and backend issues
• Architecture and code reviews
• Refactoring AI-generated or legacy code
• ASP.NET Core APIs, authentication, and EF Core
• MCP, RAG, LLM APIs, and AI-agent integration
• System design and production-readiness reviews
• CV, GitHub, interview, and career mentoring for .NET developers
My sessions are practical and outcome-focused: we inspect the real problem, identify the root cause, implement or plan the solution, and leave you with clear next steps.
I build production AI agents for real businesses: LangGraph, MCP servers and RAG pipelines on top of .NET and Python. 21 years of .NET (1.0 to .NET 10); most recently Solutions Architect for a 1,800-person advisory firm.
Stuck on an agent, a RAG pipeline, or getting Claude Code or Cursor to write better code? Let's fix it live.
What I help with:
• AI agents & orchestration: LangGraph, LangChain, Claude Agent SDK, OpenAI Agents SDK, Microsoft Agent Framework (Semantic Kernel + AutoGen)
• Model Context Protocol (MCP): building and debugging MCP servers in C#, TypeScript and Python
• RAG: pgvector, chunking, retrieval quality, evaluation
• Production AI: observability, LLM cost tracking, prompt-injection defense
• AI coding workflows: Claude Code, Cursor, OpenAI Codex, GitHub Copilot, Google Antigravity
• Adding AI to existing .NET apps without a rewrite
• Blazor Server & WebAssembly, ASP.NET Core, ASP.NET Zero / ABP
• C# debugging, performance, EF Core & SQL Server
• Architecture and code reviews, Azure deployment & CI/CD
Open source I maintain: .NET Agent Framework, AgentWire (LLM/MCP gateway), CostWire (LLM cost dashboard), MCP Server Template, CKEditor5-Blazor.
Anthropic certificates (2026): Building with Claude API · Model Context Protocol · Agent Skills · Sub-Agents.
Past work includes platforms for The New York Times and Walmart. My style is hands-on: we find the root cause, fix it together, and make sure you understand the fix.
If you're stuck, let's get you unstuck.

Hello! My name is Yogi Grantz and I began my career in software development long before the era of .net as a mainframe programmer for the State of Ohio. I then worked for the San Diego County Office of Education in 2003, when object oriented programming and .net framework just started to bloom. Since then, I have grown significantly as a developer and I am now working intensely with various types of .net 6 & .net 8 solutions: class libraries, console, winform, mvc, webapi, razor, blazor, and started R&D in .net MAUI. I have developed many algorithms and architecture components such as class library, sample code, proof of concept, and prototypes. I have also upgraded and optimized a number of legacy c# applications, completed several full stack applications, as well as a number of utilities.
I hold Master of Science degrees in Aerospace Engineering and Industrial Engineering from Mississippi State University. I love to solve problems and create algorithms and functionalities. I hope to contribute my expertise to help those who are developing c#-based software.
Hi, I'm Nicolas, a backend engineer with 7+ years of experience building Java/Spring Boot services for banking, automotive certification, IoT and media companies.
I'm product-minded: I like owning features end to end, understanding why users need them, and challenging requirements when a simpler flow serves them better. On an IoT smart-locker platform, for example, I pushed for auto-logout after borrowing and a multi-item rental cart; on a film-production tool, I proposed a .docx export so clients could customise their own reports instead of us maintaining one template per client.
Highlights:
\- Banking: replaced a third-party tool handling international transfers and migrated the architecture to the cloud; parallelised legacy payment-file conversion, cutting processing time from 60 to ~10 minutes.
\- Automotive certification: lead backend developer on vehicle valuation and repair-cost estimation; coordinated an offshore team and mentored two junior developers.
\- Code quality: brought critical Sonar issues on a project from 80 down to 0.
Certified Kubernetes Administrator, Azure Fundamentals and CAPM. French native, fluent in English and Spanish. Based in Valencia, Spain, open to remote full-time and freelance roles.
