You will get Performance Optimization for Your .NET / ASP.NET Core API
Rising Talent
Project details
Your .NET API is slow, timing out, or struggling under load?
I can help identify the root cause and optimize it for stability and performance. Because after 13+ years of backend engineering experience and 27+ enterprise systems delivered, I specialize in diagnosing performance bottlenecks in production APIs and implementing scalable solutions.
I help improve:
• Slow API response times
• Database query bottlenecks
• Inefficient backend logic
• Memory and CPU performance issues
• Poor API architecture and scalability
Typical improvements include:
1-Query optimization (SQL Server / mySQL/PostgreSQL)
2- Async and thread optimization
3-API response time improvements
4-Caching strategies (Redis / in-memory)
5-Clean refactoring for maintainability
My focus is identifying the real performance bottleneck and implementing clean, scalable fixes that keep your system stable as it grows.
