Node/PostgreSQL Backend Optimization Audit

We are looking for an experienced Backend Consultant with strong expertise in Node.js and PostgreSQL to review and improve our existing backend system.
This is not a basic development role — we need someone who can think like a system architect and help us optimize, scale, and refine our backend.

Scope of Work

You will work closely with our team to:

1. Architecture & Code Review
Review current backend architecture and folder structure
Identify design flaws and suggest scalable improvements
Recommend best practices for modular and maintainable code

2. API & Flow Optimization
Analyze request/response flow
Improve API structure (REST standards / performance)
Suggest better error handling, validation, and middleware usage

3. PostgreSQL Optimization
Review database schema and relationships
Optimize queries and indexing strategies
Suggest improvements for performance and scalability
Ensure proper normalization (or intentional denormalization)

4. Code Quality & Best Practices
Identify anti-patterns and inefficiencies
Suggest improvements in:
Code structure
Naming conventions
Reusability
Security practices

5. Strategic Guidance
Suggest better approaches where needed
Help us build a scalable backend for future growth

Required Skills
Strong experience with Node.js (Express or similar frameworks)
Deep understanding of PostgreSQL
Experience in backend architecture & system design
Knowledge of:
REST API best practices
Authentication & authorization
Performance optimization
Experience working with scalable SaaS or CPaaS systems is a plus

Project Type
Short-term consulting (with possibility of long-term engagement)

What We’re Looking For
We are specifically looking for:
Someone who can analyze and improve, not just build
Someone who can challenge our current approach
A developer who thinks like a product + system owner
