Hi, I’m Ivan Tsarev, a backend .NET developer with 6+ years of experience building and maintaining business logic for client interfaces and external APIs (REST, gRPC, WCF). I led the migration of an API service to Core WCF, reducing memory usage and improving stability, and I designed a reporting service that generates PDF and DOCX documents while integrating with storage and delivery systems. I enjoy delivering robust, scalable software and keeping architectures clean and maintainable. I value continuous learning, code reviews, and clear communication. I’m based in Stuttgart, Germany, and in my spare time I enjoy electronics, chess, guitar, drawing, and hiking.…Hi, I’m Ivan Tsarev, a backend .NET developer with 6+ years of experience building and maintaining business logic for client interfaces and external APIs (REST, gRPC, WCF).
