About this gig
Stuck on a Stubborn Bug? Let's Fix It.
Hi there, I'm Langesh.
I'm a full-stack developer with 5 years of hands-on experience. I've spent a large part of my career untangling messy code and resolving critical server failures. Whether your frontend is glitching, your backend keeps crashing, or your cloud deployment is failing, I know exactly where to look.
I Can Fix Issues In:
Frontend:
- React JS
- Next JS
- Redux, state management
- Responsive UI glitches
Backend:
- Node.js server crashes
- Express API routing errors
- Middleware issues
- Optimize backend logic
Databases:
- MongoDB
- PostgreSQL
- Prisma ORM
- Slow query optimization
Infrastructure:
- AWS/GCP/DigitalOcean/Hostinger/VPS deployment errors
- CI/CD pipelines
- Web Server & Nginx/Proxy
- SSL Issues
Why work with me?
I don't just patch things up temporarily. I write clean, documented code so the bug doesn't come back. I take pride in delivering reliable work, and I can usually turn around critical fixes within 24 hours.
Please message me with your error log or a brief description of what's broken before you place an order! Let's get your app running smoothly again.

FAQ
What do you need from me to get started?
To fix your bug quickly, I will need a clear description of the issue or the error log. Depending on the bug, I may also need access to your source code (via GitHub, GitLab, or a zip file) and server access (SSH, AWS IAM, or hosting panel) if it's an infrastructure issue.
How long does it take to fix a bug?
For most frontend glitches or minor backend errors, I deliver within 24 hours. If it is a complex database optimization or a severe server infrastructure issue, it might take a bit longer. Please message me first so I can give you an exact timeframe!
I don't know what is causing the error. Can you still help?
Absolutely! You don't need to be a technical expert. Just tell me what you are experiencing (e.g., "my website is loading very slowly" or "users can't log in") and I will diagnose the root cause and fix it.
Will my source code and server credentials be safe?
Yes, 100%. I treat your data and code with strict confidentiality. I only use your credentials to fix the specific issue, and I highly recommend you create temporary access passwords that you can revoke or change as soon as the order is completed.
Do you also add new features, or just fix bugs?
I am a full-stack developer, so I can definitely build new features, integrate APIs, or develop full applications from scratch! If you need custom development, please send me a message, and I will create a custom offer for you.
