About Me

I’m Rajasekar Su, a .NET engineer with years of experience building APIs and backend systems.

Over the years I’ve worked through real problems, performance issues, EF Core gotchas, API design decisions made under deadline - to know what actually matters versus what just sounds good in blog posts. This blog is where I document that.

When I’m not writing code, I’m farming - a completely different kind of problem-solving.

What This Blog Is About

Most .NET content online is either too basic or too abstract. This blog sits in the middle - practical, day-to-day .NET development focused on what you actually encounter when building and maintaining internal applications.

You’ll find content on:

• .NET Web API and C# : patterns that work in everyday codebases
• SQL Server and Entity Framework Core : including the parts that quietly hurt performance
• API design decisions : trade-offs, not just theory
• Monolith applications : because that’s what most teams are actually building and shipping

No hype. No over-engineered solutions. Just things that work.

Who This Is For

If you’re building or maintaining .NET backends and want honest, experience-backed content - this is for you. Junior, mid-level, or senior. The goal is always to be immediately useful.
