José Manuel Guerrero Rodrigues

Freelance software engineer specializing in .NET / C# backend. Design and develop custom solutions for companies: systems architecture, APIs, application modernization, and process automation. Work end-to-end, from client analysis to production deployment, with a focus on maintainable, scalable, and well-documented code.

Backend and technical leadership in parking and meter management systems: a product environment with a high volume of events from field devices.

I technically led the evolution of the TEMPO Enterprise system, from requirements gathering and client interaction to coordinating development and supporting critical production incidents. I defined the stack and architecture for a new deployment tool and migrated a legacy solution to .NET 8 and .NET MAUI in six months, covering the entire cycle: analysis, design, stabilization, and production deployment in real environments.

On the cloud side, I developed and maintained the backend of the Lince system with ASP.NET Core Web API, EF Core, and microservices, applying DDD and CQRS in the design. I implemented structured logging with NLog to improve traceability and incident diagnosis. I acted as a technical reference and mentor for junior and mid-level profiles, promoting code maintainability and quality.

Full-stack development on ProDX, a platform from the Werfen group, a world leader in clinical diagnostics and laboratory medicine. Object-oriented backend (.NET) and frontend with AngularJS, covering analysis, development, and incident resolution with agile methodology (Scrum), in an environment with the reliability demands of the clinical sector.
