You will get Your API and FrontEnd bugs fixed and security improvement.
Project details
Are broken APIs or mysterious security errors blocking your launch?
I am a Full Stack Engineer specializing in "emergency" bug fixes for modern stacks. I don't just patch the symptoms; I find the root cause in your architecture to ensure the bug never returns.
What I can solve for you TODAY:
Security & Auth: Fixing broken JWT flows, OAuth issues, and high-priority CORS errors.
Backend (Node/Python): Resolving 500 Internal Server Errors, middleware crashes, and slow database queries.
Frontend (Vue/React): Fixing reactivity bugs, state management loops, and responsive UI breaks.
Deployment: Repairing Dockerfile configurations and Railway/Vercel deployment failures.
How it works:
You provide repo access and the error log.
I reproduce the issue locally and apply the fix.
I push the clean code and provide a brief explanation of the change.
Stop guessing why your code is broken. Let’s fix it now.

Node.js, Vue & React Expert | API Repair, Web Security & Docker Fixes
Tangier, Morocco - 9:01 pm local time
As a Full Stack Engineer, I specialize in identifying and resolving critical issues in Express.js, Vue.js, React, and Python (Flask) environments. I don't need long onboarding calls—I just need access to the error logs and the code.
My Workflow:
You provide Repo access (GitHub/GitLab).
I reproduce the bug or security vulnerability locally.
I push the clean, tested fix directly to your branch.
My Core Solutions:
API & Backend Repair: Fixing errors in Express/Flask, optimizing slow SQL queries, and debugging broken middleware.
Web Security: Patching CORS errors, fixing JWT authentication failures, securing headers, and preventing Injection/XSS attacks.
DevOps & Containers: Resolving Docker container crashes, writing clean Dockerfiles.
Frontend Debugging: Solving Vue.js reactivity issues, React hook loops, and state management (Vuex/Redux) bugs.
My Guarantee: I am focused on speed and precision. If I can't fix the issue, you don't pay.
Available to start immediately. send me the error log, and let's get your system running again.
Steps for completing your project
After purchasing the project, send requirements so Salman can start the project.
Delivery time starts when Salman receives requirements from you.
Salman works on your project following the steps below.
Revisions may occur after the delivery date.
Codebase Access & Bug Reproduction
Once the project starts, you will provide access to your GitHub or GitLab repository. I will clone the codebase and set up the environment locally to reproduce the specific bug or security vulnerability you reported.
Debugging & Implementation
I will identify the root cause of the issue. I will then write the clean, optimized code to fix the problem without breaking other parts of your architecture.
