I will review your nestjs or typescript backend architecture
Christodoulos L
About this gig
The problem with most backend code reviews: They focus on syntax. They miss the bigger picture.
I'm a Senior Software Engineer and Engineering Team Lead with hands-on experience building production microservices at scale TypeScript, NestJS, Node.js, PostgreSQL, AWS. I've led engineering teams, designed microservice architectures from scratch, and shipped real products under real pressure.
What I actually look at:
- Module structure & separation of concerns
- Dependency injection patterns & coupling risks
- Database query efficiency & ORM anti-patterns
- API design, DTOs, validation, and error handling
- Authentication/authorization architecture
- Scalability bottlenecks before they become production fires
- Missing abstractions that will hurt you later
What you get: A structured written report delivered within the agreed timeframe no fluff, no vague advice. Just clear findings ranked by priority with concrete recommendations you can act on immediately.
Who this is for:
- Startup founders building their first serious backend
- Junior/mid devs who want a senior eye before going to production
- Teams inheriting legacy NestJS codebases
- Anyone who wants honest feedback, not validation
Who this is NOT for:

Senior Software Engineer and Engineering Team Lead with 7+ years building production backend systems.
I specialize in TypeScript, NestJS, and Node.js microservices — designing systems from scratch, leading engineering teams, and shipping real products under real pressure. Most recently at Instashop, one of the MENA region's leading delivery platforms.
I work async-first. No unnecessary calls, no fluff — just solid engineering delivered on time.
FAQ
How do I share my code with you?
GitHub repo access (private is fine), a ZIP file, or a shared drive link. Whatever works for you.
Do we need to get on a call?
No. Everything is async. You share the code, I deliver a written report. Simple.
What if my project uses a custom NestJS setup?
Send me a message first with a quick description. I'll confirm whether I can help before you order.
Can you also review the frontend?
My focus is backend only. I won't pretend to be a frontend expert.
Is my code kept confidential?
Yes. I don't share, store, or reuse any client code. Happy to sign an NDA for the Premium package.
