I build complete web products—from clear interfaces to reliable backend systems.
Computer Science graduate with a backend-leaning full-stack focus. I build with TypeScript, Next.js, Node.js, and ASP.NET Core—turning business rules into usable, production-minded web products.

About
Full-stack range. Backend depth.
I care about how a product behaves under real rules—not only how its screens look.
I work across the full product path: understanding the workflow, shaping the data model, building the API, connecting the interface, and validating the result. My strongest area is backend engineering, while my full-stack range helps me make practical decisions across the whole system.
Interfaces & APIs
Architecture & data
- 01
Model the workflow
I turn real multi-step journeys—booking, handover, reporting, and moderation—into explicit states and rules.
- 02
Protect the boundaries
I pay attention to authentication, authorization, validation, data exposure, and consistency between operations.
- 03
Verify what ships
Type checks, automated tests, end-to-end coverage, CI, and production diagnostics are part of the build.
Technical capabilities
A practical stack across product layers.
Every item below is supported by the CV, repositories, or the implementation inside Aoun and UniEvents.

Featured full-stack product
Aoun
Arabic in-kind donation coordination platform
A full-stack platform for listing donated items, publishing needs, matching offers, managing bookings and waitlists, coordinating safe handovers, and handling communication and moderation.

The problem
In-kind donations are often scattered across separate posts, messages, and handover arrangements. Aoun brings that journey into one role-based system.
My contribution
Built the product end to end across a Next.js frontend and a TypeScript Native ESM backend. I designed the workflows, API boundaries, authorization, real-time communication, transaction-sensitive booking logic, and operational safeguards.
Product capabilities
- Item listings, search, filters, bookings, and waitlists
- Need requests and donor offer workflows
- Safe-hub and direct handover confirmation
- Real-time chat, notifications, ratings, reports, and appeals
- Role-based admin controls and configurable platform policies
01
Authentication & access
JWT access and refresh tokens with rotation and reuse detection, HMAC-hashed OTP verification, RBAC, secure cookies, and Redis-backed rate limiting.
02
Data consistency
MongoDB transactions and per-user locks protect booking and quota operations; atomic queries prevent duplicate waitlist and offer states.
03
Realtime & operations
Socket.IO powers chat and notifications, with Redis adapter support, a durable outbox worker, managed indexes, and liveness/readiness checks.
04
Architecture & quality
Layered controllers, services, repositories, and DTOs with TypeScript checks, automated tests, Playwright E2E coverage, and GitHub Actions CI.

The problem
Manual university event registration makes capacity, cancellations, attendance, and waiting lists difficult to coordinate consistently.
My contribution
Built the ASP.NET Core MVC application using C# controllers, Razor views, Entity Framework Core, and SQL Server, including the student and admin workflows from booking through check-in.
Product capabilities
- Session-based authentication and Student/Admin role separation
- Capacity-aware booking with duplicate booking prevention
- FIFO waitlist promotion after cancellation or capacity expansion
- PDF ticket generation, verification, and attendance check-in
- Admin analytics and Excel booking exports
01
Booking state machine
Bookings move between active, waiting, cancelled, and checked-in states based on capacity and user actions.
02
Automatic waitlist
The earliest waiting booking is promoted when a confirmed attendee cancels, and additional places are filled when capacity increases.
03
Operational tooling
Administrators can verify tickets, record attendance, view booking summaries, and export event registrations to Excel.
