I will diagnose and optimize aspnet core and mssql performance

Sobre este Serviço
Are server crashes and slow APIs costing your business thousands?
Stop paying for expensive Azure/AWS scale-ups to mask bad code. I specialize in rescuing failing enterprise systems. As a 19-year veteran managing platforms with 2.4M+ monthly visitors, I know true performance requires surgical precision. I diagnose and stabilize your infrastructure to scale your bottom line.
WHAT I SOLVE:
- Unexplained IIS Recycles & 500/504 Errors
- Severe MSSQL CPU/Memory Spikes (>95%)
- Sluggish APIs & EF Core Query Bottlenecks
- Cascading Failures & "Double Faults"
MY PROVEN RESULTS (See Portfolio):
- Prevented a $45K+ monthly loss by resolving a critical architecture loop.
- Reduced enterprise API load times by 63% via strategic indexing.
THE APEX PROCESS:
1. Diagnostic Audit (Basic): Telemetry analysis & C-Level Prescription Report.
2. Surgical Fix (Standard): Targeted, zero-disruption code & DB optimizations.
3. Architecture Rescue (Premium): Full system refactoring & load testing.
*Strict Read-Only Safety & NDAs respected.*
PLEASE CONTACT ME BEFORE ORDERING to discuss your specific bottlenecks.

Perguntas frequentes
Do you need full access to my production database and source code?
For the Basic Diagnostic, I only require read-only access to logs and telemetry. If we advance to Standard/Premium surgical fixes, I work under strict enterprise NDAs and prioritize deploying all refactored code to your staging environment first to ensure system stability and security.
Will your optimization work cause downtime for my active users?
I engineer non-disruptive solutions with a focus on zero downtime. Database optimizations use online operations to avoid table locks, and all refactoring is validated in staging to ensure a seamless transition for live traffic.
What exactly will I receive in the Diagnostic Audit Report (Basic Package)?
I provide a C-level PDF report that pinpoints exact code lines and inefficient queries causing bottlenecks. It includes a root cause analysis, architectural data flows, and a phased, actionable plan to stabilize your system, going far beyond generic automated scans.
