You will get Stabilize your .NET backend and fix production issues
Project details
I help SaaS teams stabilize .NET backends by resolving critical production issues with a clear, low-risk process. If you are dealing with recurring errors, unstable APIs, slow endpoints, or fragile releases, I can diagnose and fix high-impact problems quickly.
Starter includes diagnosis and a fix plan for one issue. Standard and Advanced include implementation of confirmed fixes, validation notes, and deployment/rollback guidance. I focus on practical engineering outcomes: fewer incidents, better performance, and safer releases.

About Carlos
Senior .NET Backend Engineer | Backend Reliability, SQL Performance
Ovar, Portugal - 11:29 pm local time
Most of my production experience is in .NET backend systems, especially APIs, SQL-heavy workflows, background processing, and incident-driven debugging. The work I do is usually in existing systems where failures are expensive to leave unresolved: recurring production incidents, slow endpoints, fragile releases, data inconsistency, and hard-to-reproduce bugs.
Typical work includes:
- Root-causing backend incidents and recurring failures
- Investigating slow SQL queries and API bottlenecks
- Fixing data inconsistency across services, jobs, and databases
- Delivering controlled fixes for risky regressions and release-blocking issues
What you can expect:
- Clear diagnosis and a prioritized fix plan
- Targeted implementation with validation notes
- Pragmatic communication and predictable delivery
Core experience:
C#, .NET / ASP.NET Core, SQL Server, REST APIs, Redis, Azure
Also comfortable with:
Python for backend and data-oriented work, especially when it supports debugging, automation, or data-intensive services
I work best with teams that need rigorous debugging, technically sound fixes, and someone who can step into an existing codebase and make progress quickly.

After purchasing the project, send requirements so Carlos can start the project.
Delivery time starts when Carlos receives requirements from you.
Carlos works on your project following the steps below.
Revisions may occur after the delivery date.
Kickoff and access review
I review access, architecture context, environment, and issue details to confirm scope and priorities.
Issue triage and reproduction
I analyze logs and code paths, reproduce the issue when possible, and identify the most likely root cause.
