You will get expert bug fixes and code review for your Node.js or Next.js project
Project details
Stuck on a bug? Need a second pair of eyes on your code? I'll dig in and fix it properly not just patch over the symptom.
I'll review your codebase, identify the root cause, and fix the issue with clean, documented code. Or if you want a code review before launching, I'll go through your repo and give you actionable feedback on architecture, performance, and maintainability.
What's included:
• Root cause analysis (not just quick patches)
• Clean, documented fix with explanation
• Code review with written feedback
• PR-ready commits or detailed recommendations
• Quick turnaround
Tech I work with: Node.js, Next.js, React, TypeScript, PostgreSQL, AWS, .NET/C#.
My background: Nearly 3 years debugging and refactoring high-traffic iGaming platforms tracking down race conditions, fixing performance bottlenecks, and reviewing code from teams of 9+ developers.
Good fit for: Developers stuck on a tricky bug, teams wanting a pre-launch review, or founders who inherited messy code and need help making sense of it.
Message me with details and I'll confirm if I can help.

About Simon
Full Stack Developer with specialisation in AWS
Guaruja, Brazil - 11:34 am local time
I'm a full-stack developer specializing in AWS and Next.js, with a focus on solution architecture. That means I think beyond just writing code: I design systems that are maintainable, cost-effective, and built for growth.
My background includes backend development, microservices, containerization, and leading technical projects across gaming and web platforms. I've optimized systems under heavy load and mentored engineering teams along the way.
What I typically help with:
* AWS infrastructure design and deployment
* Full-stack development (Next.js, Node.js, TypeScript)
* API design and backend architecture
* Migrating or modernizing existing systems
Currently pursuing AWS Solutions Architect certification to formalize expertise I've been applying in practice.
If you're weighing technical options or need someone who can both architect a solution and build it, let's talk.
Steps for completing your project

Review the codebase and reproduce the issue
I'll clone your repo, get it running locally, and reproduce the bug (or start the code review). I'll message you if I need more context.
Identify root cause and fix
I'll track down the actual problem and implement a clean fix or complete the review and document my findings.
