👨‍💻 Manar Hasan – Backend Developer Portfolio

Hi, I’m Manar – a software engineer with 4+ years of professional experience across backend and fullstack roles. My background includes event-driven architectures, complex REST APIs, scheduling systems, and integrations with payment providers like Cybersource. Below are select examples of projects I’ve contributed to.

📆 Paleat – Food Delivery Platform Backend

Stack: NestJS · MongoDB · Swagger · Heroku · Firebase

A scalable food delivery backend powering vendors, drivers, and customers. Developed RESTful endpoints and role-based guards to support admin, manager, and user access. Worked on category handling, cart system, inventory, and order management.

🔐 Admin Dashboard API (NestJS)

Guard-based route protection (AdminGuard, ManagerGuard, UserGuard)
Integrated Cybersource for payment processing and refund flow
Used MongoDB for flexible schema and document-based tracking

🏢 Gamiphy – Loyalty & CMS Backend

Stack: NestJS · MongoDB · RabbitMQ · Firebase

Contributed to a modular backend system supporting gamification mechanics, CMS features, and loyalty rewards. Supported multiple enterprise clients through tenant-aware services and asynchronous job flows.

Used RabbitMQ for event/message propagation between services
Firebase integration for real-time user data and auth sync

🕒 Job Scheduling System

This custom NestJS scheduler uses dayjs.tz for timezone-aware triggers. It handles retries, in-progress states, failure recovery, and emits events that are expected to update their own runAt timestamps.

🌎 3YS – Event Management Platform

Stack: NestJS · PostgreSQL · React (Vite) · AWS · TypeScript

Modernized and expanded a previously broken project for a Dubai-based events company. When inherited, the system could only read data via Postman. It now features a clean, fully functional admin panel.

Built out new backend endpoints and restructured models to support complete CRUD functionality
Designed and implemented a new admin dashboard in React from scratch
Integrated secure user access and added quality-of-life features for operational flow
Migrated infrastructure to multi-stage AWS environments

🎨 Tactical RPG 2.5D (Godot Game Development)

Stack: Godot (GDScript), 2.5D Tile System, Custom UI

A personal passion project exploring tactical combat in a 2.5D grid environment.

Developed character movement and attack systems
Turn-based round logic, job system, and stat balancing
Focused on gameplay mechanics and AI behavior over visuals

📅 The Real TPL (Django Bootcamp Project)

Stack: Django · PostgreSQL · HTML/CSS · JavaScript

Bootcamp capstone project, created during the Coding Dojo program.

User authentication, admin tools, and blog-like content management
REST API exposure with Django REST framework
Good demonstration of early understanding of clean MVC structure

📖 Additional Projects
