.NET developer needed for SaaS project - scope for .NET full stack engineer
We worked with Vic as .NET developer on troubleshooting our SaaS platform, and overall the experience was outstanding. He quickly got a good understanding of our product and was able to find and fix issues that had been affecting performance for a while. As a full stack developer, he handled both backend and frontend work, including also Angular, and API-related tasks, without overcomplicating things. Communication was steady and clear, and we always felt informed about progress and next steps. He didn’t just patch issues but actually improved how parts of the system work, which made a noticeable difference for us. Overall, a dependable .NET developer who clearly knows what he is doing and can be trusted with complex tasks.
