About this gig
Struggling with a JavaScript, React, NodeJS, or API bug? I will debug and fix it, delivered at a fixed price with a written explanation of what was wrong and what changed.
WHAT I FIX
Frontend: broken layouts, CSS rendering bugs, JavaScript errors, React state issues, broken forms, responsive failures
Backend: broken endpoints, failed API calls, NodeJS crashes, incorrect data mapping, auth and token errors, webhook failures
Integrations: REST and GraphQL errors, CORS failures, fetch and axios issues, payload parsing bugs
WHAT I NEED FROM YOU
A specific bug with steps to reproduce it, access to the relevant code (repo or files), and the environment where the fix should be verified.
NOT INCLUDED
Vague investigations with no reproducible steps, multiple bugs in one order, refactoring, new features, or bugs in stacks outside HTML, CSS, JavaScript, NodeJS, Python, REST APIs.
HOW IT WORKS
1. You describe the bug with repro steps and share code access
2. I investigate, apply the fix, and test it in your environment

I build landing pages, n8n automation workflows, and targeted bug fixes - defined deliverable, defined price, no retainers.
Background: 9 years as a backend and full-stack engineer, including 6 years at Salesforce building internal tooling and integrations.
Three fixed-scope services: landing pages (HTML/CSS/JS), n8n automation workflows connecting your tools via API, and bug fixes for frontend, backend, and integration issues.
You get a clear scope, a fixed quote, and working code. No retainers, no vague estimates.

FAQ
Do you need the full codebase or just the relevant files?
Just the relevant files — the specific component, endpoint, or integration where the bug lives. You don't need to share the entire codebase. A repo link with instructions on where to look works fine too.
What if you can't reproduce the bug?
I'll let you know before touching anything. If I can't reproduce it from the steps provided, I'll tell you what additional information I need. I don't charge for a fix I can't confirm is resolved.
Do I own the fixed code?
Yes. It's your code — I'm applying a fix to it. Everything delivered is yours. No license, no ongoing dependency on me.
What if you find additional bugs while investigating?
I'll flag them and quote separately. This gig covers the specific bug described — not a general audit of the surrounding code. Additional issues discovered are out of scope unless separately agreed.
What stacks do you work in?
Frontend: HTML, CSS, JavaScript. Backend: Node.js, Python, REST APIs. Integrations: n8n workflows, webhooks, OAuth flows, third-party API connections. Mobile native, WordPress/Elementor, Shopify themes, and C++ are outside my lane.
What's your revision policy?
Revisions cover the original bug only. If the fix doesn't resolve the stated issue, I'll fix it within the revision count for your tier. New bugs, changed requirements, or issues outside the original scope are quoted separately.
