You will get expert bug fixing, performance optimization, and code refactoring

Project details
Is your API slow? Is your server crashing randomly? Or is your code just a mess that needs cleaning?
Bugs and slow performance kill user experience. If you are stuck with a "500 Internal Server Error" or a database query that takes forever to load, you need a Senior Engineer to look under the hood.
I am a Node.js & NestJS Expert who specializes in debugging and performance tuning. I don't just put a band-aid on the problem; I find the root cause and fix it permanently.
Why choose me? I have debugged high-scale production systems. I know how to track down memory leaks, optimize event loops, and secure APIs without breaking existing functionality.
Don't let bugs slow you down. Order now to get your app running smoothly again.

Frequently asked questions
About Obi
Senior Fullstack Developer | NestJS, React & Microservices Expert
Lagos, Nigeria - 1:48 am local time
Most clients come to me when their product needs more than just features. They need clean APIs, predictable performance, and an architecture that can grow without constant rewrites. I focus on building systems that are easy to maintain, easy to extend, and safe to scale.
My work is centered on backend-heavy full-stack development, with a strong emphasis on API design and application structure.
What I typically help with:
✅Designing and building REST APIs using NestJS and Node.js
✅Developing scalable backend architectures with PostgreSQL or MongoDB
✅Building clean, responsive dashboards and admin panels with React and Next.js
✅Integrating third-party services such as payments, authentication, and external APIs
✅Improving existing codebases by fixing performance issues and restructuring poorly designed systems
I value clear communication and steady progress. You will always know what is being built, why it is being built, and what comes next. I do not disappear mid-project, and I do not overpromise.
If you are looking for a developer who understands both the technical and practical side of building real products, I am ready to help.
Send a message with a brief description of your project, and I will respond with clear next steps.
