You will get a role-based access control system for your Node.js backend
Project details
I'll replace your scattered permission checks with a centralized RBAC system — governed, consistent, and easy to extend as your team grows.
Scope of work:
• Role and permission architecture design
• Middleware-based route protection
• Admin, user, and custom role support
• Clean TypeScript implementation
• Dynamic permission assignment (Premium)
• Audit logging for sensitive actions (Premium)
I led a platform-wide RBAC rollout that governed every protected route across a system serving 7,000+ institutions. I'll bring that exact approach to your codebase.
Basic: 2 roles + route guards
Standard: 4 roles + granular permissions
Premium: Dynamic RBAC + audit log + full TypeScript
Message me before purchasing to discuss your existing role structure.

Ahsan delivered a high-quality full-stack application very quickly with excellent communication and clear understanding of requirements. Highly recommended.
About Ahsan
Senior Backend Engineer | Node.js | API Design & Payment Integrations
Sylhet, Bangladesh - 2:53 pm local time
with a high-traffic backend that is slowing down under real load?
I am a Senior Backend and Full-Stack Engineer specializing in production-grade
Node.js and Next.js systems. Over the past two years, I have engineered
multi-tenant architectures for software platforms serving 1,000,000+ students
across 7,000+ institutions — handling $100,000+ in monthly revenue at 99.9%
uptime.
When you hire me, you are not hiring someone to write code. You are hiring an
engineer focused on business outcomes, data integrity, and cost efficiency.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT I DO BEST
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
▸ Payment & Billing Infrastructure
Unified processing layers across Stripe, Paddle, and Xendit — with
fail-safe webhook architecture that eliminates double-charging and
partial-write data corruption.
▸ Database Optimization
I rescue slow APIs. Through composite indexing, query rewrites, and
schema redesign, I consistently reduce MySQL response times by 10–30%
on the highest-traffic production endpoints.
▸ SaaS & Multi-Tenant Architecture
Secure Role-Based Access Control, real-time connection-pooled services,
and multi-tenant systems designed for scale from day one.
▸ Cloud Cost Optimization
Migrated transactional email infrastructure to AWS SES and moved asset
storage to AWS S3 — reclaiming 14+ GB of production database storage
and cutting ongoing vendor costs.

PRODUCTION METRICS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✔ $100,000+ monthly revenue handled at 99.9% uptime
✔ 1,000,000+ users across 7,000+ institutions on a single platform
✔ 14+ GB of database storage reclaimed via S3 migration
✔ Real-time services stabilized under thousands of concurrent connections

CORE STACK
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Backend → Node.js, Adonis.js, Django, REST API, Webhooks, Redis
Frontend → React.js, Next.js, Redux, TypeScript
Database → MySQL (Atomic Transactions, Composite Indexing), Redis
Cloud → AWS SES, AWS S3, Docker, Linux
Other → Codeforces Specialist (1400+ rating) — strong algorithmic
problem-solving background

If you need an engineer who takes full ownership of your backend, understands
real-world scalability, and ships systems that survive production traffic —
let's talk.
Steps for completing your project
After purchasing the project, send requirements so Ahsan can start the project.
Delivery time starts when Ahsan receives requirements from you.
Ahsan works on your project following the steps below.
Revisions may occur after the delivery date.
Role & Permission Architecture Mapping
I review your existing authentication setup, map out your desired system capabilities, and define a relational schema structure to handle role-to-user mappings cleanly
Policy & Centralized Middleware Layer Setup
I create the core authentication and authorization middleware handlers in TypeScript to intercept incoming API traffic and parse user permissions efficiently
