Senior Backend .NET Developer — Palermo, Italy

20+ years designing and building high-reliability backend systems in C#/.NET: REST APIs, SQL Server performance tuning, asynchronous messaging and CI/CD automation, in regulated and business-critical environments. Here I publish libraries, tools and experiments — with a focus on performance, code quality and AI engineering applied to .NET.

• CSharp.Essentials — helper library for C#, published on NuGet: zero-dependency plugin architecture bootstrapped via ModuleInitializer (no reflection scans at startup); HTTP middleware built on ArrayPool that avoids ~256 KB of LOH allocations per request
• github-projectpulse-mcp — Model Context Protocol (MCP) server in TypeScript
• Csharp.Essentials.Extensions — extensions for the CSharp.Essentials ecosystem

C# · .NET · ASP.NET · SQL Server · PostgreSQL · Redis · EF Core · Dapper · RabbitMQ · Kafka · Docker · Azure DevOps · Elasticsearch · OpenTelemetry · xUnit · TypeScript · MCP · LLM integration

• ~25× faster development of new services through a shared core-hub architecture
• 300 concurrent transactions with 7–8 ms average processing time on SQL Server
• Simultaneous deployment of ~25 services automated through a custom Azure DevOps extension (Node.js)
