I am starting a new project that revolves around ASP .NET Core 8 (C# 12). The priority is pure backend work: designing and coding a robust API layer that will let intelligent agents plug into our existing business systems in real time. The heart of the job is the “connexion d’agents IA” aspect. You will be creating MCP-compliant services that expose context, receive agent actions, and safely persist results. While the immediate focus is this AI bridge, your code must stay clean and extensible so we can later hook the same backbone to front-end interfaces or even an eventual Sage 100 connector. To move forward I need a detailed project proposal outlining: • the architecture you would follow for an MCP server under ASP .NET Core 8 • the way you will secure, test and document each endpoint • milestones with clear success criteria and the metrics you will use to prove the agent connection works (latency, throughput, error rate) Please draw on any past similarities, but keep the proposal concise and specific to this use-case. French is our working language; remote collaboration is fine as long as communication stays smooth. I will review proposals that show concrete technical depth and an execution roadmap I can track from day one.

Les rejouements d’actions MCP ne doivent jamais créer de résultats en double. Je structurerai l’API ASP.NET Core 8 en couches séparant contrats MCP, logique métier, adaptateurs des systèmes existants et persistance SQL Server. Les tools/resources exposés resteront indépendants du transport et du futur connecteur Sage 100. Chaque action sensible utilisera validation stricte, autorisation par politique, journal d’audit, idempotency key et gestion claire des timeouts. Le suivi se fera en trois jalons : cadrage des contrats et flux MCP avec tests d’acceptation ; implémentation sécurisée avec tests unitaires, intégration et scénarios d’échec ; validation en charge et documentation OpenAPI/MCP. Les critères incluront connexion agent démontrable, persistance vérifiée, p95 de latence, débit soutenu et taux d’erreur mesuré. Communication et livrables seront en français. Votre agent utilisera-t-il MCP via Streamable HTTP uniquement, ou faut-il aussi prévoir un transport local stdio ?

Hi! This is something we can handle without problem. One thing before I put together a proper proposal: the brief mentions a future Sage 100 connector as a likely next step — how firm is that? It changes some design decisions early on (how we model the context layer, how we structure the service boundaries), so I'd rather account for it now than retrofit it later. On the technical side: we'd build the MCP server as a set of ASP .NET Core 8 minimal API endpoints, secured with JWT + scoped API keys per agent, documented via OpenAPI, and tested with a mix of unit and integration tests against a real SQL Server instance. For the metrics you mentioned (latency, throughput, error rate) we'd wire in structured logging from day one so you can track agent interactions without any guesswork. The budget range shown is quite wide for what's described — once I understand the Sage 100 scope and how many agent actions/tools you're planning to expose in this first phase, I can give you a realistic number. Happy to keep going on this over messages. Gustavo & the DoTheCode team

Hi, I read your post for "Backend .NET AI Integration" and it lines up closely with the AI / ML work I do day to day. How I would approach it: 1. Agree the success metric before any modelling starts -- accuracy, latency, or cost per call -- so "done" means the same thing to both of us. 2. Stand up a small end-to-end baseline first. You see real output on your data early rather than at the end. 3. Iterate on the baseline, and hand over evaluation scripts plus notes so the numbers are reproducible on your side, not just mine. Directly relevant to your listed skills: .NET, .NET Core, AI Integration, API Development, ASP.NET, Backend Development, C# Programming, Microsoft SQL Server, Model Context Protocol (MCP), Software Architecture. My bid is $213 against your $30-250 range, and I can start straight away. Let's connect to discuss this further -- happy to walk you through the approach and cover anything you want nailed down before you decide. Thanks for reading. Best regards, Ashish & Team

Hi, I’ve reviewed your ASP .NET Core 8 backend AI integration brief closely, and I can design a clean MCP-compliant API layer that connects intelligent agents to your business systems securely and in real time. This project aligns well with my experience in Software Architecture and Web Services, including backend API design, system integration, and extensible service layers built for future connectors. I would structure the ASP.NET backend around clear service boundaries, secure endpoint contracts, action validation, persistence workflows, and measurable observability for latency, throughput, and error rate. I can also define testing, documentation, and milestone-based delivery so you have a roadmap you can track from day one, while keeping the codebase ready for future frontend or Sage 100 integration. I can start by outlining the architecture and milestone plan, then move into implementation and validation within 14 days. Do you already have a defined MCP protocol contract and agent action schema, or should I design both from scratch? Best regards, KANIKA

★•══•★ Hi client ★•══•★ I’m excited about building your ASP .NET Core 8 API layer for intelligent agent connections. My approach focuses on designing a clean, modular MCP-compliant service architecture that’s easy to extend later for front-end or Sage 100 integration. Security will be top priority with token-based authentication and input validation. I’ll cover thorough testing—unit, integration, and load tests—to keep latency low and error rates minimal. Documentation will be clear and automated for every endpoint. I’ll break the work into milestones: architecture design with diagrams, secure API implementation, testing & performance tuning, and final delivery with metrics on throughput and reliability. I’ve done similar backend projects connecting AI services where reliability and clean code were critical. Communication in French won’t be an issue; I’m all about keeping things smooth remotely. What’s the main business system this API needs to plug into? Best regards, Rico

Hi, I am a .NET backend developer with 8 years of rich experience in software development, with a background in API architecture, AI integration, and business-system connectivity. I am familiar with ASP.NET Core 8, C# 12, .NET Core, REST APIs, Model Context Protocol (MCP), Microsoft SQL Server, authentication/authorization, automated testing, logging, and AI agent integration. For your backend, I would structure the MCP layer as a clean ASP.NET Core service exposing controlled context/resources and agent actions through well-defined endpoints, with validation, permission checks, audit logging, and persistence separated from the transport layer. I can also define measurable acceptance criteria around latency, throughput, error rate, endpoint coverage, and successful agent round-trips so each milestone is easy to verify and the same architecture can later support frontend clients or a Sage 100 connector. I'm an individual freelancer and can work on any time zone you want. Please contact me with the best time for you to have a quick chat. Looking forward to discussing more details. Thanks. Emile.
