Luis Sanchez
À propos de ce service
Having trouble with a Python script, FastAPI backend, SQL query, or API that is not working as expected?
I will diagnose the issue, identify the root cause, and implement a focused fix based on the agreed scope.
I can help with:
Python errors and exceptions
FastAPI endpoint issues
REST API debugging
SQL and PostgreSQL query problems
Backend logic and data validation errors
Database-related bugs
Failed or incorrect data processing
Testing and verification after the fix
My approach is diagnosis first. I review the error, expected behavior, relevant code, logs, and technical context before making changes.
Package scope:
Basic: 1 small reproducible issue
Standard: up to 2 related issues
Premium: up to 3 related backend issues
You will receive the corrected source code within the agreed scope and a clear explanation of what was fixed.
Please message me before ordering if the issue involves a large codebase, deployment, authentication, third-party services, major database changes, security, new features, or unclear requirements.
New development, major refactoring, full application recovery, and functionality outside the agreed issue are not included by default and may require a custom of

FAQ
1. What do you need from me before starting?
Please provide a clear description of the problem, the expected behavior, the actual behavior, any error messages or logs, and the relevant code or files. If possible, include the steps required to reproduce the issue.
2. Should I contact you before placing an order?
Yes, especially if the issue involves a large project, multiple components, databases, external APIs, authentication, deployment, or unclear technical requirements. I can review the scope first and confirm which package is appropriate.
3. What counts as one issue?
One issue is a specific, reproducible technical problem with a defined expected behavior. Multiple unrelated bugs, new features, or problems in different systems may require a larger package or a custom offer.
4. Do you guarantee that every technical issue can be fixed?
No technical issue should be guaranteed before it is properly diagnosed. I first review the available evidence, code, logs, dependencies, and environment. If the problem cannot be resolved within the agreed scope, I will clearly explain the findings and the next recommended steps.
5. Are new features or complete application development included?
No. This Gig is focused on diagnosing and fixing existing Python, FastAPI, SQL, database, and API issues. New features, major refactoring, complete applications, complex deployments, security work, and large migrations require separate scope and pricing.
