Small tools that actually do the job.
A handful of free, no-nonsense developer utilities — built by a backend and database engineer, not generated marketing filler. Real analysis, real processing, no accounts.
SQL Query Doctor
Paste a SQL Server query (and optional execution plan) for an instant static-analysis report — non-sargable predicates, missing indexes, cursors, and more.
Live 📄PDF Toolkit
Merge multiple PDFs into one, split a PDF into separate pages, or convert images into a PDF — all processed and returned instantly, nothing kept.
Live 🔍API Schema Analyzer
Paste a JSON API response for a review of naming consistency, null handling, leaking internal fields, and pagination/versioning red flags.
Live 🏗️.NET Architecture Checker
Paste a C# class or Program.cs/Startup.cs for anti-pattern detection — sync-over-async deadlocks, async void, God classes, empty catch blocks, and more.
Built by Abdur Rahim — a Software Engineer working in .NET, ASP.NET Core, and SQL Server. These tools exist because they're genuinely useful, and because if one of them saves you real time, the underlying problem is often worth fixing properly — that's what the consulting work is for.
